935,000,000,000 YBN | 4) There is a pattern in the universe. Light particles move from highly dense volumes of space to volumes of less density. In low density volumes, light particles slowly accumulate to form atoms of Hydrogen and Helium which exist as gas clouds (like the Magellanic Clouds or Orion nebula). These gas clouds, called nebulae continue to accumulate trapped light particles. At points of high density planets and stars form and the cloud is eventually dense enough to become a galaxy of stars. The stars emit light particles back out to the rest of the universe, where the light again becomes trapped and forms new clouds. Around each star are many planets and pieces of matter. On many of the planets rotating around stars, living objects evolve that can copy themselves by converting matter around them into more of them. Living objects need matter to replace matter lost from the constant emitting of light particles (decay). Like bacteria, these living objects grow in number, with the most successful organisms occupying and moving around many stars. These advanced organisms then move the groups of stars they control, as a globular cluster, away from the plane of the spiral galaxy. As time continues, all of the stars of a galaxy are occupied by living objects who have organized their stars into globular clusters, and these globular clusters together, form a globular galaxy. The globular galaxy may then exist for a long time living off the matter emitting from stars, in addition to the accumulation of light particles from external sources. So free light particles are trapped into volumes of space that grow in density first forming atoms, then gas clouds, then stars, a spiral galaxy, and finally a globular galaxy. Stars at our scale may be light particles at a much larger scale, just as light particles at our scale may be stars at a much smaller scale. This system may go on infinitely in both larger and smaller scale. |

Lynds' Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only easily seen in long telescopic exposures of the region. LDN 1622 lies near the plane of our Milky Way Galaxy, close on the sky to Barnard's Loop - a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of Orion. But the obscuring dust of LDN 1622 is thought to be much closer than Orion's more famous nebulae, perhaps only 500 light-years away. At that distance, this 1 degree wide field of view would span less than 10 light-years. PD source: http://apod.nasa.gov/apod/image/ 0705/ldn1622_carboni.jpg | |

Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023, this is not the only nebula in the sky to evoke the imagery of flowers. Still, this beautiful digital image shows off the Iris Nebula's range of colors and symmetries in impressive detail. Within the Iris, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the dusty clouds glow with a faint reddish photoluminesence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula may contain complex carbon molecules known as PAHs. As shown here, the bright blue portion of the Iris Nebula is about six light-years across.

M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the constellation Sagittarius. The wave-like patterns of gas have been sculpted and illuminated by a torrent of ultraviolet radiation from young, massive stars, which lie outside the picture to the upper left. The glow of these patterns accentuates the three-dimensional structure of the gases. The ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds. The warmed surfaces glow orange and red in this photograph. The intense heat and pressure cause some material to stream away from those surfaces, creating the glowing veil of even hotter greenish gas that masks background structures. The pressure on the tips of the waves may trigger new star formation within them. The image, roughly 3 light-years across, was taken May 29-30, 1999, with the Wide Field Planetary Camera 2. The colors in the image represent various gases. Red represents sulfur; green, hydrogen; and blue, oxygen.

4,370,000,000 YBN | 40) A protein can copy RNA. This protein is called an RNA polymerase, and may be more efficient than RNA itself, at copying other RNA molecules. |
[1] RNA is a versatile molecule. In its most familiar role, RNA acts as an intermediary, carrying genetic information from the DNA to the machinery of protein synthesis. RNA also plays more active roles, performing many of the catalytic and recognition functions normally reserved for proteins. In fact, most of the RNA in cells is found in ribosomes--our protein-synthesizing machines--and the transfer RNA molecules used to add each new amino acid to growing proteins. In addition, countless small RNA molecules are involved in regulating, processing and disposing of the constant traffic of messenger RNA. The enzyme RNA polymerase carries the weighty responsibility of creating all of these different RNA molecules. The RNA Factory RNA polymerase is a huge factory with many moving parts. The one shown here, from PDB entry 1i6h, is from yeast cells. It is composed of a dozen different proteins. Together, they form a machine that surrounds DNA strands, unwinds them, and builds an RNA strand based on the information held inside the DNA. Once the enzyme gets started, RNA polymerase marches confidently along the DNA copying RNA strands thousands of nucleotides long. Accuracy As you might expect, RNA polymerase needs to be accurate in its copying of genetic information. To improve its accuracy, it performs a simple proofreading step as it builds an RNA strand. The active site is designed to be able to remove nucleotides as well as add them to the growing strand. The enzyme tends to hover around mismatched nucleotides longer than properly added ones, giving the enzyme time to remove them. This process is somewhat wasteful, since proper nucleotides are also occasionally removed, but this is a small price to pay for creating better RNA transcripts. Overall, RNA polymerase makes an error about once in 10,000 nucleotides added, or about once per RNA strand created. Poisoning Polymerase Since RNA polymerase is absolutely essential for the life of the cell, it is a sensitive target for poisons and toxins. The most powerful of these poisons is alpha-amanitin, a small circular peptide created by the death cap mushroom. Eating even one of these mushrooms will lead to coma and death in a manner of days, as the poison attacks RNA polymerase throughout the body. Surprisingly, it binds on the back side of RNA polymerase, away from the active site and away from the binding site for the DNA and RNA. It does not physically block the active site, like most inhibitors, but instead jams the mechanism of the enzyme. RNA polymerase is a highly mobile enzyme, that flexes and changes shape as it performs the sequential steps of binding to DNA, unwinding it, and then building the RNA strand. As seen in PDB entry 1k83, the poison binds between two subunits of the protein, gluing them together and blocking these essential motions.

[1] These simple DNA polymerases are shaped roughly like a hand. Both are from bacteria: on the left is the enzyme from Escherichia coli, PDB entry 1kln, and on the right is the enzyme from Thermus aquaticus, PDB entry 1tau. A cleaved version of the E. coli enzyme was studied: the missing part, which you will not find in the PDB file, is shown with a green outline. The space between the ''fingers'' and the ''thumb'' is just the right size for a DNA helix. But surprisingly, DNA actually fits into the palm when the enzyme is at work. In these pictures, the template strand is colored purple and the new strand is colored green. The enzyme contains three separate active sites. The polymerase site, near the top in these pictures, synthesizes the new strand by adding nucleotides. The 3'-5' exonuclease site, near the center in the E. coli polymerase, proofreads the new additions. The polymerase from Thermus aquaticus does not have this proofreading ability--perhaps the heat in which it lives performs the same function. At the bottom is the 5' exonuclease site that later removes the small RNA fragments that are used to prime DNA replication. These illustrations were created with RasMol. You can create similar pictures by clicking on the accession codes, and then hitting ''View Structure.''

PD source: http://upload.wikimedia.org/wiki pedia/commons/d/dc/Urzwerg.jpg [2] Figure 1) Changing views of the tree and timescale of life. a) An early-1990s view, with the tree determined mostly from ribosomal RNA (rRNA) sequence analysis. This tree emphasizes vertical (as opposed to horizontal) evolution and the close relationship between eukaryotes and the Archaebacteria. The deep branching (>3.5 Giga (109) years ago, Gya) of CYANOBACTERIA (Cy) and other Eubacteria (purple), the shallow branching (approx1 Gya) of plants (Pl), animals (An) and fungi (Fu), and the early origin of mitochondria (Mi), were based on interpretations of the geochemical and fossil record7, 8. Some deeply branching amitochondriate (Am) species were believed to have arisen before the origin of mitochondria44. Major symbiotic events (black dots) were introduced to explain the origin of eukaryotic organelles42, but were not assumed to be associated with large transfers of genes to the host nucleus. They were: Eu, joining of an archaebacterium host with a eubacterium (presumably a SPIROCHAETE) to produce an amitochondriate eukaryote; Mi, joining of a eukaryote host with an alpha-proteobacterium (Ap) symbiont, leading to the origin of mitochondria, and plastids (Ps), joining of a eukaryote host with a cyanobacterium symbiont, forming the origin of plastids on the plant lineage and possibly on other lineages. b) The present view, based on extensive genomic analysis. Eukaryotes are no longer considered to be close relatives of Archaebacteria, but are genomic hybrids of Archaebacteria and Eubacteria, owing to the transfer of large numbers of genes from the symbiont genome to the nucleus of the host (indicated by coloured arrows). Other new features, largely derived from molecular-clock studies16, 39 (Box 1), include a relatively recent origin of Cyanobacteria (approx2.6 Gya) and mitochondria (approx1.8 Gya), an early origin (approx1.5 Gya) of plants, animals and fungi, and a close relationship between animals and fungi. Coloured dashed lines indicate controversial aspects of the present view: the existence of a premitochondrial symbiotic event and of living amitochondriate eukaryotes, ancestors of which never had mitochondria. c) The times of divergence of selected model organisms from humans, based on molecular clocks. For the prokaryotes (red), because of different possible origins through symbiotic events, divergence times depend on the gene of interest. source: http://www.nature.com/nrg/journa l/v3/n11/full/nrg929_fs.html | |

Trees constructed with other genes are generally similar, although they may place some early-branching groups very differently, thanks to long branch attraction. The exact relationships of the three domains are still being debated, as is the position of the root of the tree. It has also been suggested that due to lateral gene transfer, a tree may not be the best representation of the genetic relationships of all organisms.

This intersection is the model initial composition for the samples at 2800 Ma. The position above the growth curve indicates that the samples evolved with high μ (238U/204Pb) values of 22 during the time span from 3700 to 2800 Ma.

(a) 207Pb/204Pb versus 206Pb/204Pb for eight samples of >3700 Ma pelagic sediment from Isua, West Greenland, shown with open diamonds. Analytical uncertainty is less than the size of the symbols. The Stacey and Kramers growth curve for average crustal Pb [24] is shown for comparison. The age of the errorchron which has a MSWD=52 is calculated using Isoplot [23]. The high MSWD value indicates that the Pb isotopic composition of the sample suite was not perfectly homogeneous at 2800 Ma. (b) Pb isotopic data for the whole rock samples shown in panel a and their HCl leachates and leach residues in the range 206Pb/204Pb=0–75 and 207Pb/204Pb=10–25 (filled circles). The full dataset is shown in the inset. In open circles are data for banded iron formation and metabasalt samples from the same supracrustal segment as the carbon-rich metasediments. These samples plot along a parallel reference isochron, but originate at the Stacey and Kramers growth curve, which indicates that they evolved with ‘normal’ μ (238U/204Pb) values during the time span from 3700 to 2800 Ma. (c) Close-up of the region near the Stacey and Kramers growth curve showing the intersection of the errorchron defined by the metasediment samples and an isochron defined by all possible Pb compositions at 2800 Ma of systems derived from the Stacey and Kramers growth curve at 3700 Ma. This intersection is the model initial composition for the samples at 2800 Ma. The position above the growth curve indicates that the samples evolved with high μ (238U/204Pb) values of 22 during the time span from 3700 to 2800 Ma. (d) 206Pb/204Pb versus 208Pb/204Pb for the sample suite. The samples show some scatter about a regression line, which passes to the right of the Stacey and Kramers growth curve. This indicates that the metasediments evolved with low Th/U ratios. At the initial 206Pb/204Pb composition derived from panel b, the 208Pb/204Pb value at the regression line is 31, which is less radiogenic than the Stacey and Kramers model value at 3700 Ma. This indicates that the samples evolved with virtually no Th during the early Archaean. (e) 206Pb/204Pb versus 208Pb/204Pb for whole rock samples, HCl leachates and residues. The residues are highlighted in filled diamonds, and are characterized by low thorogenic Pb and a shallow array indicative of a low Th/U ratio, while the leachates shown in open circles are extremely radiogenic, with high Th/U evolutions. Whole rock samples are shown with crosses. The model initial Pb composition at 2769 Ma is shown as the open square at the apex of the fan-shaped data array to the right of the Stacey and Kramers growth curve.

Researchers have found L. monocytogenes in at least 37 mammalian species, both domesticated and feral, as well as in at least 17 species of birds and possibly in some species of fish and shellfish. Laboratories can isolate L. monocytogenes from soil, silage, and other environmental sources. L. monocytogenes is quite hardy and resists the deleterious effects of freezing, drying, and heat remarkably well for a bacterium that does not form spores. Most L. monocytogenes are pathogenic to some degree. source: http://en.wikipedia.org/wiki/Ima ge:Listeria.jpg [2] These are bacteria (about 0.3 µm in diameter) that do not have outer walls, only cytoplasmic membranes.

2,730,000,000 YBN | 80) Endo and exocytosis. Cells can now eat other cells. In endocytosis the plasma membrane folds inward to bring substances into the cell. In Exocytosis substances contained in vesicles are discharged from the cell. |
[1] Endocytosis and Exocytosis: For example, this electron micrograph is showing the process of exocytosis . The process begins by fusion of the membranes at the peripheral pole of the granule. Then an opening is created which widens to look like an omicron figure. This opening allows the granular material to be released. The membrane is now part of the plasma membrane and any proteins carried with it can be incorporated into the plasma membrane. Note that there is no coating on the membrane. This figure was taken from Alberts et al, Molecular Biology of the Cell, Garland Publishing Third Edition, 1994 In contrast, this micrograph shows a figure which looks something like an omicron, however, this view is showing receptor mediated endocytosis of virus particles. In both cases, the membrane is coated with clathrin and these represent classical receptor mediated endocytosis profiles. Most ligands cannot be visualized by themselves, like a virus particle. Therefore, the cytochemist must attach label to the ligand. Alternatively, the cytochemist could immunocytochemically detect the receptor with antibodies that recognize the extracellular domain. This figure was taken from Endocytosis, Edited by Ira Pastan and Mark C. Willingham, Plenum Press, N.Y., 1985 COPYRIGHTED source: http://www.cytochemistry.net/cel l-biology/end7.jpg [2] Pinocytosis In the process of pinocytosis the plasma membrane froms an invagination. What ever substance is found within the area of invagination is brought into the cell. In general this material will be dissolved in water and thus this process is also refered to as ''cellular drinking'' to indicate that liquids and material dissolved in liquids are ingested by the cell. This is opposed to the ingestion of large particulate material like bacteria or other cells or cell debris. source: http://academic.brooklyn.cuny.ed u/biology/bio4fv/page/endocytb.htm | |
2,700,000,000 YBN | 60) Eukaryotic cell. The first cell with a nucleus. The first protist. The nucleus may develop from the infolding of plasma membrane. In prokaryotic cells the DNA is not membrane enclosed while in eukaryotic cells most of the DNA is contained in a nucleus. Eukaryotic cells are generally much larger than prokaryotic cells. Unlike prokaryotic cells, eukaryotic cells have a cytoskeleton. Eukaryotic cells may have mitochondria and plastids, which prokaryotic cells lack. DNA in prokaryotic cells is usually a single circular chromosome, while DNA in the nucleus of eukaryotes contains linear chromosomes. Like prokaryotes, this cell is probably haploid (a single unique DNA), most eukaryotes are diploid (having two sets of DNA). All protists, fungi, animals and plant cells descend from this common eukaryotic cell. |

2,690,000,000 YBN | 208) The eukaryote flagellum and cilia evolve. |
[1] Cilia and flagella are projections from the cell. They are made up of microtubules , as shown in this cartoon and are covered by an extension of the plasma membrane. They are motile and designed either to move the cell itself or to move substances over or around the cell. The primary purpose of cilia in mammalian cells is to move fluid, mucous, or cells over their surface. Cilia and flagella have the same internal structure. The major difference is in their length. This figure shows a cross section of a cilium next to a longitudinal section. Below, we will see how the microtubules are organized in the core (shown in the cartoon in this figure). Also shown is the centriole or basal body that organizes the formation and direction of the cilia. COPYRIGHTED source: Description Transmission electron microscope image, showing an example of green algae (Chlorophyta). Chlamydomanas reinhardtii is a unicellular flagellate used as a model system in molecular genetics work and flagellar motility studies. This image is a longitudinal section through the flagella area. In the cell apex is the basal body that is the anchoring site for a flagella. Basal bodies originate from and have a substructure similar to that of centrioles, with nine peripheral microtubule triplets(see structure at bottom center of image). The two inner microtubules of each triplet in a basal body become the two outer doublets in the flagella. This image also shows the transition region, with its fibers of the stellate structure. The top of the image shows the flagella passing through the cell wall. Date 20 September 2007 Source Source and public domain notice at http://remf.dartmouth.edu/imagesindex.ht ml Author Dartmouth Electron Microscope Facility, Dartmouth College PD [2] This figure shows an electron micrograph of a cross section of a cilium. Note that you can see the dynein arms and the nexin links. The dynein arms have ATPase activity. In the presence of ATP, they can move from one tubulin to another. They enable the tubules to slide along one another so the cilium can bend. The dynein bridges are regulated so that sliding leads to synchronized bending. Because of the nexin and radial spokes, the doublets are held in place so sliding is limited lengthwise. If nexin and the radial spokes are subjected to enzyme digestion, and exposed to ATP, the doublets will continue to slide and telescope up to 9X their length.

If DNA is pictured as a twisted ladder, its sides, made of sugar and phosphate molecules, are connected by (c) rungs made of chemicals called bases. DNA has four bases—adenine, thymine, guanine, and cytosine—that form interlocking pairs. The order of the bases along the length of the ladder is the DNA sequence.

The sediments are essentially rust-free. After the late Proterozoic, sedimentary deposits often have reddish colors and are called red beds due to the presence of iron-oxide coatings between sand grains.

[1] Figure 1: Figure 1. Eukaryote phylogeny integrating ultrastructure, sequence trees, gene fusions and molecular cladistic markers. The unikont topology is established, but the branching order of the six bikont groups remains uncertain. The single enslavement [12] of a red alga (R) to create chromalveolates is supported by a plastid glyceraldehyde phosphate dehydrogenase (GAPDH) replacement [13]. Whether there was a single enslavement of a green alga (G) to form cabozoa or two separate enslavements (asterisks) to form Cercozoa and Excavata is uncertain [12], as is the position of Heliozoa [14]. Polyubiquitin [15] and EF-1α[16] insertions strongly support the clades core Rhizaria and opisthokonts.

The times for each node are taken from the summary times in Table 1, except for nodes 1 (310 Ma), 2 (360 Ma), 3 (450 Ma), and 4 (520 Ma), which are from the fossil record [25]; nodes 8 (1450 Ma) and 16 (1587 Ma) are phylogenetically constrained and are the midpoints between adjacent nodes. Nodes 12–14 were similar in time and therefore shown as a multifurcation at 1000 Ma; likewise, nodes 21–22 are shown as a multifurcation at 1967 Ma. The star indicates the occurrence of red algae in the fossil record at 1200 Ma, the oldest taxonomically identifiable eukaryote [12]. Hedges et al.

[1] Fig. 2. The tree of life based on molecular, ultrastructural and palaeontological evidence. Contrary to widespread assumptions, the root is among the eubacteria, probably within the double-enveloped Negibacteria, not between eubacteria and archaebacteria (Cavalier-Smith, 2002b); it may lie between Eobacteria and other Negibacteria (Cavalier-Smith, 2002b). The position of the eukaryotic root has been nearly as controversial, but is less hard to establish: it probably lies between unikonts and bikonts (Lang et al., 2002; Stechmann and Cavalier-Smith, 2002, 2003). For clarity the basal eukaryotic kingdom Protozoa is not labelled; it comprises four major groups (alveolates, cabozoa, Amoebozoa and Choanozoa) plus the small bikont phylum Apusozoa of unclear precise position; whether Heliozoa are protozoa as shown or chromists is uncertain (Cavalier-Smith, 2003b). Symbiogenetic cell enslavement occurred four or five times: in the origin of mitochondria and chloroplasts from different negibacteria, of chromalveolates by the enslaving of a red alga (Cavalier-Smith, 1999, 2003; Harper and Keeling, 2003) and in the origin of the green plastids of euglenoid (excavate) and chlorarachnean (cercozoan) algae—a green algal cell was enslaved either by the ancestral cabozoan (arrow) or (less likely) twice independently within excavates and Cercozoa (asterisks) (Cavalier-Smith, 2003a). The upper thumbnail sketch shows membrane topology in the chimaeric cryptophytes (class Cryptophyceae of the phylum Cryptista); in the ancestral chromist the former food vacuole membrane fused with the rough endoplasmic reticulum placing the enslaved cell within its lumen (red) to yield the complex membrane topology shown. The large host nucleus and the tiny nucleomorph are shown in blue, chloroplast green and mitochondrion purple. In chlorarachneans (class Chlorarachnea of phylum Cercozoa) the former food vacuole membrane remained topologically distinct from the ER to become an epiplastid membrane and so did not acquire ribosomes on its surface, but their membrane topology is otherwise similar to the cryptophytes. The other sketches portray the four major kinds of cell in the living world and their membrane topology. The upper ones show the contrasting ancestral microtubular cytoskeleton (ciliary roots, in red) of unikonts (a cone of single microtubules attaching the single centriole to the nucleus, blue) and bikonts (two bands of microtubules attached to the posterior centriole and an anterior fan of microtubules attached to the anterior centriole). The lower ones show the single plasma membrane of unibacteria (posibacteria plus archaebacteria), which were ancestral to eukaryotes and the double envelope of negibacteria, which were ancestral to mitochondria and chloroplasts (which retained the outer membrane, red).

[1] Volvoxcell differentiation. The pathways leading to germ cells or somatic cells are controlled by genes that cause cells to follow one or the other fate. Mutations can prevent the formation of one of these lineages. http://www.devbio.com/chap02/link0204.sh tml Although all the volvocaceans, like their unicellular relative Chlamydomonas, reproduce predominantly by asexual means, they are also capable of sexual reproduction, which involves the production and fusion of haploid gametes. In many species of Chlamydomonas, including the one illustrated in Figure 2.10, sexual reproduction is isogamous (“the same gametes”), since the haploid gametes that meet are similar in size, structure, and motility. However, in other species of Chlamydomonas—as well as many species of colonial volvocaceans—swimming gametes of very different sizes are produced by the different mating types. This pattern is called heterogamy (“different gametes”). But the larger volvocaceans have evolved a specialized form of heterogamy, called oogamy, which involves the production of large, relatively immotile eggs by one mating type and small, motile sperm by the other (see Sidelights and Speculations) UNKNOWN source: http://www.ncbi.nlm.nih.gov/book s/NBK10031/bin/ch2f12.jpg [2] Description English: Four Different Species of Volvocales Algae.

[1] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes.

The cells are cylindrical with a rounded anterior and tapered posterior. The chloroplasts are well-developed, bright green, and sometimes have pyrenoids. They are often discoidal in shape but can also be ovate, lobate, elongate, U-shaped, or ribbon-shaped. Some researchers use the structure and position of the chloroplasts to divide the group into three subgenera. Even though they are able to photosynthesize, Euglena cells also have a phagotrophic ingestion apparatus. Euglena has one long, protruding flagellum and a shorter flagellum that is not usually visible. The euglenoids can glide and swim using their flagella, or can ooze along a substrate with an undulating, shape-changing, contraction motion called metaboly. The cytoplasm of Euglena and other euglenoids contains many paramylon starch storage granules. The euglenoid cells are covered by a pellicle composed of ribbonlike, woven strips of proteinaceous material that cover the cell in a helical arrangement from apex to posterior. Freshwater euglenoids have a contractile vacuole. Euglenoids sense light using a red pigmented eyespot or stigma and the paraflagellar body located at the base of the emergent flagella.

Cytokinesis does not usually follow mitosis, so the cells retain multiple nuclei. The thallus has cross walls only where gametes or zoospores were produced, and may be branched. The cytoplasm of Vaucheria is pushed to the cell periphery by large vacuoles, and contains many nuclei and discoid plastids. The plastids can change their orientation in response to changes in light levels. The large cells rely on cytoplasmic streaming to move materials around as needed. Researchers have found fossils in one billion- year-old Siberian deposits that are very similar to Vaucheria, indicating that the genus has been evolving for quite some time.

The stages include (1) spore at ''resting'' stage, (2) germinating spore, (3) hyphal stage. It is believed that there are two forms of Ichthyophonus, both belonging to one genus. One of them is known as the ''salmon'' form, occuring in freshwater and cold-preferring sea fishes: this form is characterized by its ability to produce long tubulose germ hyphae. The other is called the ''aquarium fish'' form, typical of the tropical freshwater fishes. This form is completely devoid of hyphae. Developmental cycle of Ichthyophonus hoferi: 1-5 - development of ''daughter'' spores, 7-11 - development of resting spore from the ''daughter'' spore, 12-19 - development of resting spore by fragmentation.

[1] FIG. 2. The tree of life based on molecular, ultrastructural and palaeontological evidence. Contrary to widespread assumptions, the root is among the eubacteria, probably within the double-enveloped Negibacteria, not between eubacteria and archaebacteria (Cavalier-Smith, 2002b); it may lie between Eobacteria and other Negibacteria (Cavalier-Smith, 2002b). The position of the eukaryotic root has been nearly as controversial, but is less hard to establish: it probably lies between unikonts and bikonts (Lang et al., 2002; Stechmann and Cavalier-Smith, 2002, 2003). For clarity the basal eukaryotic kingdom Protozoa is not labelled; it comprises four major groups (alveolates, cabozoa, Amoebozoa and Choanozoa) plus the small bikont phylum Apusozoa of unclear precise position; whether Heliozoa are protozoa as shown or chromists is uncertain (Cavalier-Smith, 2003b). Symbiogenetic cell enslavement occurred four or five times: in the origin of mitochondria and chloroplasts from different negibacteria, of chromalveolates by the enslaving of a red alga (Cavalier-Smith, 1999, 2003; Harper and Keeling, 2003) and in the origin of the green plastids of euglenoid (excavate) and chlorarachnean (cercozoan) algae-a green algal cell was enslaved either by the ancestral cabozoan (arrow) or (less likely) twice independently within excavates and Cercozoa (asterisks) (Cavalier-Smith, 2003a). The upper thumbnail sketch shows membrane topology in the chimaeric cryptophytes (class Cryptophyceae of the phylum Cryptista); in the ancestral chromist the former food vacuole membrane fused with the rough endoplasmic reticulum placing the enslaved cell within its lumen (red) to yield the complex membrane topology shown. The large host nucleus and the tiny nucleomorph are shown in blue, chloroplast green and mitochondrion purple. In chlorarachneans (class Chlorarachnea of phylum Cercozoa) the former food vacuole membrane remained topologically distinct from the ER to become an epiplastid membrane and so did not acquire ribosomes on its surface, but their membrane topology is otherwise similar to the cryptophytes. The other sketches portray the four major kinds of cell in the living world and their membrane topology. The upper ones show the contrasting ancestral microtubular cytoskeleton (ciliary roots, in red) of unikonts (a cone of single microtubules attaching the single centriole to the nucleus, blue) and bikonts (two bands of microtubules attached to the posterior centriole and an anterior fan of microtubules attached to the anterior centriole). The lower ones show the single plasma membrane of unibacteria (posibacteria plus archaebacteria), which were ancestral to eukaryotes and the double envelope of negibacteria, which were ancestral to mitochondria and chloroplasts (which retained the outer membrane, red). source: http://aob.oxfordjournals.org/cg i/content/full/95/1/147/FIG2 [2] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria. The tree shown is based on a consensus of molecular (1-4) and ultrastructural (16, 17) data and includes a rough indication of new ciPCR ''taxa'' (broken black lines) (7-11).

[1] FIG. 2. The tree of life based on molecular, ultrastructural and palaeontological evidence. Contrary to widespread assumptions, the root is among the eubacteria, probably within the double-enveloped Negibacteria, not between eubacteria and archaebacteria (Cavalier-Smith, 2002b); it may lie between Eobacteria and other Negibacteria (Cavalier-Smith, 2002b).

[1] English: This diagram is showing the difference of the two major types of coelomates: the protostomes (molluscs, annelids, arthropods, ...) and deuterostomes (echinoderms, vertebrates, ...). These groups differ in several characteristics of early development; In deuterostomes blastula devisions is called ''radial cleavage'' because it occurs parallel or perpendicular to the major polar axis. In protostomes the cleavage is called ''spirale'' because division planes are oriented obliquely to the polar major axis. During gastrulation, protostomes embryos' mouth was given first by the blastopore while the anus was formed later and vis versa for the deuterostomes. As examples : Squids are protostomes. Sea urchins are deuterostomes.

(B) Schematic view of a transverse section of the late planula of the anthozoan Euphyllia rugosa. The larval stage represented in A and B is constituted of an outer monocellular layer, the ectoderm, within which is an inner endodermal layer with various mesenteric folds and immature septa. This complicated bilayered structure is typical of anthozoan late planula larvae. Note the individual cells visible in the ectodermal layer at lower left in A, where it has separated from the endodermal layer. (Scale bar, 100 μm.) (C and D) Putative fossil gastrula of hydrozoan medusa; (C) Bright field; (D) Polarized light.

Individual zooids can crawl about freely within the colony, but are connected to one another by thin “cables,” quickly retracting if disturbed. What makes the Pterobranchs even stranger than corals is that these slimy, slithering weirdos are “hemichordates,” closer to us vertebrates than to invertebrates like worms and jellyfish.

[1] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria. The tree shown is based on a consensus of molecular (1-4) and ultrastructural (16, 17) data and includes a rough indication of new ciPCR ''taxa'' (broken black lines) (7-11).

[1] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria. The tree shown is based on a consensus of molecular (1-4) and ultrastructural (16, 17) data and includes a rough indication of new ciPCR ''taxa'' (broken black lines) (7-11). An asterisk preceding the taxon name indicates probable paraphyletic group COPYRIGHTED source: http://www.sciencemag.org/cgi/co ntent/full/300/5626/1703 [2] Figure 1. Phylogenetic hypothesis of the eukaryotic lineage based on ultrastructural and molecular data. Organisms are divided into three main groups distinguished by mitochondrial cristal shape (either discoidal, flattened or tubular). Unbroken lines indicate phylogenetic relationships that are firmly supported by available data; broken lines indicate uncertainties in phylogenetic placement, resolution of which will require additional data. Color coding of organismal genus names indicates mitochondrial genomes that have been completely (Table 1), almost completely (Jakoba, Naegleria and Thraustochytrium) or partially (*) sequenced by the OGMP (red), the FMGP (black) or other groups (green). Names in blue indicate those species whose mtDNAs are currently being sequenced by the OGMP or are future candidates for complete sequencing. Amitochondriate retortamonads are positioned at the base of the tree, with broken arrows denoting the endosymbiotic origin(s) of mitochondria from a Rickettsia-like eubacterium.

260,000,000 YBN | 232) Earliest warm-blooded and hair growing animal. Both birds and mammals are endothermic (also called "warm blooded") as opposed to many other vertebrates which are ectothermic (or "cold blooded) and cannot internally generate heat. Endothermy is the physiological maintenance, by a body, of a constant temperature independent of the external environmental temperature. Hair for insulation is correlated to endothermy. |

[1] In geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root ''to build.'' Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. The theory of plate tectonics states that the Earth's outermost layer is fragmented into a dozen or more large and small plates that are moving relative to one another as they ride atop hotter, more mobile material. Before the advent of plate tectonics, however, some people already believed that the present-day continents were the fragmented pieces of preexisting larger landmasses (''supercontinents''). The diagrams below show the break-up of the supercontinent Pangaea (meaning ''all lands'' in Greek), which figured prominently in the theory of continental drift -- the forerunner to the theory of plate tectonics.

[1] In geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root ''to build.'' Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. The theory of plate tectonics states that the Earth's outermost layer is fragmented into a dozen or more large and small plates that are moving relative to one another as they ride atop hotter, more mobile material. Before the advent of plate tectonics, however, some people already believed that the present-day continents were the fragmented pieces of preexisting larger landmasses (''supercontinents''). The diagrams below show the break-up of the supercontinent Pangaea (meaning ''all lands'' in Greek), which figured prominently in the theory of continental drift -- the forerunner to the theory of plate tectonics.

Divergence time estimates are mostly based on analyses of molecular data with fossil constraints (Wikström et al., 2001 ; Pryer et al., 2004 ) and are augmented by fossil evidence (Kenrick and Crane, 1997 ; Wellman et al., 2003 ).

Your Ancestor's Profile Dryomomys is the most primitive primate known from good fossil material. (The first known primate, Purgatorius, dating back as far as 65 million years ago, is known only from isolated teeth and jaw fragments.) The animal most like Dryomomys today is a wee being called the pen-tailed tree shrew. Dryomomys would have weighed about 1.3 ounces, roughly akin to that of the smallest living primates, the mouse lemurs of Madagascar. Like its cousin, the roughly contemporary but more advanced Carpolestes, the Dryomomys skeleton that the reconstruction is based on was unearthed in Wyoming.

[1] Llanocetus denticrenatus UNKNOWN source: http://ocean.si.edu/sites/defaul t/files/WhaleEv_04llanocetus.png?1259868 752 [2] Description Frontal view from below of the skull of a Llanocetus denticrenatus in the Sant Hall of Oceans in the Smithsonian Museum of Natural History in Washington, D.C. The name is a tribute to Dr. George Llanos, and is combined with the Latin name for whale (''cetus''). ''Denticrenatus'' means ''small-toothed.'' It is an intermediate form between toothed and baleen whales. Llanocetus denticrenatus is the oldest known mysticete (or baleen whale). It was discovered in the La Meseta Formation on Seymour Island in Antarctica in 1989. Only the skull has been unearthed so far; the skeleton has yet to be fully unearthed and described. It probably lived 34 to 35 million years ago in colder seas near the Antarctic. It had tiny peg-like teeth which jutted out in a fan-like spread from a larger tooth (which was covered over by the gums). From these teeth grew primitive baleen (stuff like your fingernails are made of). These baleen-growing teeth were very widely separated within the jaw. The skull is long and narrow, somewhat looking like a dolphin's. The upper jaw is exceptionally slender (more so than the lower jaw), and the lower jaw is exceptionally wide at the rear. It's not entirely clear what the body looked like, but it probably looked like a minke whale. It was about 30 feet long (9 m).

We merged well-supported (>70% bootstrap values) monophyletic clades at the tips with the same ordinal designation across all three classifications (e.g., 24 species called Passerines). Only higher relationships supported by bootstrap values >50% are shown. Colors are as in Fig. 2. Color bars to the right of the tree show membership in three different classifications: Peters' (25) (left), Sibley and Monroe's (30) (middle), and Livezey and Zusi's (13) (right). Black text within the bars indicates monophyletic orders in our phylogeny, whereas white text within the bars indicates nonmonophyletic orders.

[1] Australopithecus squinted at the blue African sky. He had never seen a star in broad daylight before, but he could see one today. White. Piercing. Not as bright as the Sun, yet much more than a full moon. Was it dangerous? He stared for a long time, puzzled, but nothing happened, and after a while he strode across the savanna unconcerned. Millions of years later, we know better. ''That star was a supernova, one of many that exploded in our part of the galaxy during the past 10 million years,'' says astronomer Mark Hurwitz of the University of California-Berkeley. Right: Human ancestors, unconcerned by odd lights in the daytime sky. This image is based on a painting featured in The Economist.

The disappearance of elephants helped kill off Homo erectus, and paved the way for Homo sapiens - modern humans - to take over. Findings from the University of Tel Aviv reveal how important the huge animals were to the diet of early humans - researchers that elephants provided 60 per cent of the meat eaten by Homo erectus.

95,000 YBN [93000 BC] | 594) Homo sapiens move out of Africa into Eurasia. This is the beginning of differences in race within the human species. |
[1] The northern route (along the Danube) is represented by the 'classic' Aurignacian technologies, while the southern (Mediterranean) route is represented by the 'proto-Aurignacian' bladelet technologies (Fig. 3)-with their inferred origins in the preceding early Upper Palaeolithic technologies in the Near East and southeastern Europe. Dates (in thousands of years bp) indicate the earliest radiocarbon dates for these technologies in different areas, expressed in thousands of radiocarbon years before present (bp). (These are likely to underestimate the true (calendar) ages of the sites by between 2,000 and 4,000 yr; see ref. 32). Dashed lines indicate uncertain routes. COPYRIGHTED source: http://www.nature.com/nature/jou rnal/v432/n7016/fig_tab/nature03103_F1.h tml [2] The figure shows the geographical and temporal distribution of hominid populations, based on fossil finds, using different taxonomic schemes. The new finds from Herto4, 5 (H) represent early Homo sapiens. a, This reflects the view that both Neanderthals and modern humans derived from a widespread ancestral species called H. heidelbergensis2. b, However, evidence is growing that Neanderthal features have deep roots in Europe2, 8, so H. neanderthalensis might extend back over 400,000 years. The roots of H. sapiens might be similarly deep in Africa, but this figure represents the alternative view that the ancestor was a separate African species called H. rhodesiensis. Different views of early human evolution are also shown. Some workers prefer to lump the earlier records together and recognize only one widespread species, H. erectus2 (shown in a). Others recognize several species, with H. ergaster and H. antecessor (or H. mauritanicus) in the West, and H. erectus only in the Far East8 (shown in b). Adapted with permission from refs 8, 11. 8.

The commodity counted was not indicated in the beginning, but was gradually imbedded in the numbers system or with a seal or a pictograph of the commodity added, i. e. development into ideonumerographical tablets, the forerunners to pictographic tablets. There are only about 260 numerical tablets known. Most of them are found in Iran.

Both inscriptions on the base are written in the Proto-Sinaitic alphabetic script. The inscription on the right shoulder is written in Egyptian hieroglyphs, The hieroglyphic text identifies the name of the goddess to whom the sphinx is dedicated as Hathor, “the mistress of turquoise.” The famous Egyptologist Alan Gardiner observed that each of the signs in the Proto-Sinaitic texts represented not an entire word, as in hieroglyphic, but only its initial sound. Four of these strange signs (written left-to-right) spelled the name Baalat, a Canaanite word also meaning “the Mistress.” Thus was Gardiner able to translate Baalat, the first word deciphered in alphabetic script.

3,500 YBN [1500 BC] | 6228) Water clock (Clepsydra {KlePSiDru}). | Egypt |
[1] clepsydra Egyptian clepsydra An Egyptian clepsydra Also known as a water clock, an instrument in which the discharge of water from a storage tank is monitored in order to measure the passing of time. Clepsydras were used from ancient times until the Renaissance. ''Clepsydra'' is Greek for ''water thief.'' UNKNOWN source: http://www.daviddarling.info/ima ges/Egyptian_clepsydra.jpg [2] The Karnak clepsydra In 1904, archaeological excavations within the ancient temple complex of Karnak in Egypt led to the recovery of fragments of a large conical vessel. The presence of an outlet near the base, plus calibration scales on the interior walls, showed the object to be a classic example of an outflow clepsydra. Figure 6: A full-size reconstruction of the Karnak clepsydraA full-size reconstruction (Fig. 6) may be seen in the New Walk Museum, and illustrates how it could act as a timekeeper independent of the Sun. The vessel is filled with water to a mark near the rim, and then allowed to empty via a narrow jet near the base. With a cylindrical container the rate of flow diminishes as the head of water within the pot decreases, so the water surface drops more slowly with time. The ancient Egyptian designer (Amenhemhet, about 1550 B.C.) has cleverly compensated for this by employing a conical vessel, and trials conducted during the construction of this exhibit have shown that the chosen angle gives rise to an excellent approximation to a linear descent of the water surface. The hieroglyphics covering the outside of the vessel (delineated by Dr. Sarah Symons) do not explain how the water clock was to be used: they are simply traditional decorations in praise of the gods. More information is given alongside the exhibit. UNKNOWN source: http://www.sundials.co.uk/leices ter/fig06.jpg |

Courtesy of the Israel Antiquities Authority (8) The Torah Precepts Scroll This scroll, apparently in the form of a letter, is unique in language, style, and content. Using linguistic and theological analysis, the original text has been dated as one of the earliest works of the Qumran sect. This sectarian polemical document, of which six incomplete manuscripts have been discovered, is commonly referred to as MMT, an abbreviation of its Hebrew name, Miqsat Ma`ase ha-Torah. Together the six fragments provide a composite text of about 130 lines, which probably cover about two-thirds of the original. The initial part of the text is completely missing. Apparently it consisted of four sections: (1) the opening formula, now lost; (2) a calendar of 364 days; (3) a list of more than twenty rulings in religious law (Halakhot), most of which are peculiar to the sect; and (4) an epilogue that deals with the separation of the sect from the multitude of the people and attempts to persuade the addressee to adopt the sect's legal views. The ''halakhot,'' or religious laws, form the core of the letter; the remainder of the text is merely the framework. The calendar, although a separate section, was probably also related to the sphere of ''halakhah.'' These ''halakhot'' deal chiefly with the Temple and its ritual. The author states that disagreement on these matters caused the sect to secede from Israel. References: Strugnell, J., and E. Qimron. Discoveries in the Judaean Desert, X. Oxford, forthcoming.

2,332 YBN [332 BC] | 880) Alexander is welcomed as a liberator in Egypt and was pronounced the son of Zeus by Egyptian priests of the god Ammon at the Oracle of the god at the Siwa Oasis (sometimes spelled Siwah) in the Libyan desert. Henceforth, Alexander referred to the god Zeus-Ammon as his true father, and subsequent currency featuring his head with ram horns was proof of this widespread belief. He founded Alexandria in Egypt, which would become the prosperous capital of the Ptolemaic dynasty after his death. Greek humans call Egyptian writing "hieroglyphs". "Hieros" means "sacred", "Glupho" means "sculptures". At this time hieroglyphs are only used on temple walls or public monuments, understood only by priest humans. | ||

[1] Fig 1: Byzantine, ivory casket c.1000 (from Museo Nazionale, Florence, Coll. Carrand, No.26) - earliest depiction of a rebec like instrument. Has pear shaped body blending into long narrow neck. There is a definite anchorpoint at the base, with a kind of fleur tailpiece, though the pegs appear to be missing from the depiction (no other anchorpoint is clearly indicated). There are only two strings, and the bow is very long and narrow (though it may simply be the artist trying the show that the bow is perpendicular to the surface of the strings, thus appearing flat when viewed edge on). No sound holes are shown, the soundboard seems to be a distinct, attached piece (possibly a skin covering much like in rababs). This is the instrument in transition. PD source: http://crab.rutgers.edu/~pbutler /ob09.jpg [2] Fig 2: Spanish, Catalan Psalter, c.1050. (''King David and musicians tuning their instruments'' in Bibliotheque Nationale, Paris, MS Lat. 11550, fol. 7v)- Shows a normal pear body shape. Three distinct strings, attached to a triangular tailpiece at the base, and to vertically mounted pegs at the other end. The pegbox is a round disk that appears to be made of the same piece as the neck/body, suggesting that this is a unibody construction. Again a little endpiece or endpeg is indicated. There are two round sound holes set far back on the instrument. The bow is a simple curved bow with end pressure grip (see below). This image is also somewhat suspect from the distortion of the left hand, which has the fingers curling backwards rather than forward as they actually must.

Early in the 16th century, Wan Hu decided to take advantage of China's advanced power and fireworks technology to launch himself into outer space. He had a chair built with 47 ''rockets'' attached. On the day of lift-off, Wan climbed into his rocket chair and held one enormous kite in each hand. The ignition of the 47 fuses caused a huge explosion and sent him into the sky. But unfortunately, he failed to go into orbit and his body smashed into pieces on the ground. UNKNOWN source: http://images.china.cn/images1/2 00710/410673.jpg |

The vessel was heated with the hands and partially immersed, in an upright position, in a container full of water. When the heat of the hands was taken away, the water was observed to rise in the thermoscope neck. The experiment showed the changes in air density produced by variations in temperature.

359 YBN [1641 AD] | 6244) Repeating gun. | Netherlands |
[1] Kalthoff 1641 translated with Google from: http://www.earmi.it/A-Enciclopedia/ripet izione.html The first attempt at a mechanical repetition of the shot goes back to the German Peter Kalthoff, which operates in Denmark, who in 1641 invented and built in 1646. It was a rifle with a wheel in the dust reservoir a reservoir for calcium and balls under the barrel, breech block has three rooms that can move sideways. PD source: http://www.earmi.it/A-Encicloped ia/img/Kalthoff.png [2] translated with Google from: http://www.earmi.it/A-Enciclopedia/ripet izione.html In Italy as early as 1572 the Milan Marcantonio Valgrana proposes a rifle capable of firing 4 shots below, but of questionable functionality. This was followed in 600 different mechanical repeating rifles, probably inspired by Kalthoff, but with original solutions. It certainly reminds weapon Berselli James (1660) and other Fresh Water Sebastiano (1619-1692) and the Florentine Michele Lorenzoni (died 1735). These have gone down in history as ''system Lorenzoni'' and are innovative compared to Kalthoff. Tanks for powder and ball (well 25) both are in football, behind a circular rotor driven by an external lever, the gun with the barrel is turned down so that powder and ball fall under gravity, the first movement of lever drops a ball in the barrel where it is retained by a ring of forcing, the second movement takes a dose of dust. There followed many other weapons, but none went beyond the experimental models. The technology of the time did not allow the creation of mechanisms are too delicate and until the invention of the metal cartridge case was difficult to keep the power is communicated by a charge al'altra. The first weapon is the repetition really functioning Paterson Colt revolver of 1936 followed by rifle-revolver .44 Rifle Dragon namely the Whitneyville-Hartford Dragon Colt Revolver of 1847.

345 YBN [03/25/1655 AD] | 1763) Moon of Saturn, Titan seen. | The Hague, Netherlands (presumably) |
[1] This natural color composite was taken during the Cassini spacecraft's April 16, 2005, flyby of Titan. It is a combination of images taken through three filters that are sensitive to red, green and violet light. It shows approximately what Titan would look like to the human eye: a hazy orange globe surrounded by a tenuous, bluish haze. The orange color is due to the hydrocarbon particles which make up Titan's atmospheric haze. This obscuring haze was particularly frustrating for planetary scientists following the NASA Voyager mission encounters in 1980-81. Fortunately, Cassini is able to pierce Titan's veil at infrared wavelengths (see PIA06228). North on Titan is up and tilted 30 degrees to the right. The images to create this composite were taken with the Cassini spacecraft wide angle camera on April 16, 2005, at distances ranging from approximately 173,000 to 168,200 kilometers (107,500 to 104,500 miles) from Titan and from a Sun-Titan-spacecraft, or phase, angle of 56 degrees. Resolution in the images is approximately 10 kilometers per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.

344 YBN [1656 AD] | 1764) Pendulum {PeNJUluM or PeNDUluM} clock. | The Hague, Netherlands (presumably) |
[1] Reconstruction of the pioneer pendulum clock designed by the Dutch scientist, Christiaan Huygens (1629-1693), in 1656. Huygens commissioned the clockmaker Salomon Coster of the Hague to make the clock and a patent was issued in Coster's name in 1657. It was described and illustrated by Huygen in his book, 'Horologium' in 1658. Although Galileo had suggested the use of a pendulum to count the time, Huygen's design, where the dial and hands of a clock were controlled by a pendulum, was the first truly practical pendulum clock. Huygens attached a pendulum to the gears of a clock. The regular swing of the pendulum allowed the clock to achieve greater accuracy, as the hands are turned by the falling weight, which releases the same amount of energy with each tick. Side view.

But if we allow some little lateral divergence from the extremities of the undulations, it must diminish their force, without adding materially to that of the dissipated light; and their termination, instead of the right line BG, will assume the form CH; since the loss of force must be more considerable near to C than at greater distances. This line corresponds with the boundary of the shadow in NEWTON's first observation, Fig. 1; and it is much more probable that such a dissipation of light was the cause of the increase of the shadow in that observation, than that it was owing to the action of the inflecting atmosphere, which must have extended a thirtieth of an inch each way in order to produce it; especially when it is considered that the shadow was not diminished by surrounding the hair with a denser medium than air, which must in all probability have weakened and contracted its inflecting atmosphere. In other circumstances, the lateral divergence might appear to increase, instead of diminishing, the breadth of the beam.''] PD/COPYRIGHTED source: http://journals.royalsociety.org /content/q3r7063hh2281211/?p=422e575bae4 14c9a974a16d595c628d0π=24 |

Engraving of the first reaping machine for harvesting grain, invented by Cyrus Hall McCormick (1809-1884) in 1831. As the wheel (at centre) spun, the paddles on it pushed the crop onto a moving cutter bar and knife. This design feature has been retained in modern combine harvesters although McCormick's machine was pulled by horses rather than being pushed. McCormick patented his invention in 1834, made his first sale in 1840 and moved to Chicago in 1847 to begin large-scale production. The six million harvesters he manufactured opened the prairie lands to intensive agriculture, a major factor in America's prosperity.

[1] Example of lunar parallax: Occultation of Pleiades by the Moon Example of lunar parallax from 4 points on earth This is a simulated image, combining of 4 views of the sky and the moon's location relative to the background stars at a single point in time. The bright stars visible are the star cluster Pleiades. The date March 22, 1988 was chosen because the moon occulted stars within the pleides as visible from North America. NOTE: This diagram is geometrically accurate, although not physically possible to see since the moon was not actually above the horizon in half the views. Specifically you can never see the Pleiades from the south pole! They were just picked as extreme views from the earth, the limit of what might be seen from a set of four locations in a square on a great circle and a moon just above the horizon in all four locations.

The machine traveled 120 ft (36.6 m) in 12 seconds at 10:35 a.m. at Kitty Hawk, North Carolina. Orville Wright was at the controls of the machine, lying prone on the lower wing with his hips in the cradle which operated the wing-warping mechanism. Wilbur Wright ran alongside to balance the machine, and just released his hold on the forward upright of the right wing in the photo. The starting rail, the wing-rest, a coil box, and other items needed for flight preparation are visible behind the machine. This was considered ''the first sustained and controlled heavier-than-air, powered flight'' by the Fédération Aéronautique Internationale.

No. 93-640) The French bicycle maker and engineer Paul Cornu, born in 1881 in Lisieux, France, was the first person to design and build a helicopter that achieved free flight while carrying a passenger. His twin-rotor craft flew for about 20 seconds on November 13, 1907, rising about one foot (0.3 meter) off the ground. A 24-horsepower (18-kilowatt) engine powered the helicopter, which had counter-rotating rotors. The helicopter had no effective means of control and was abandoned after a few flights. Cornu died in 1944. PD source: http://www.centennialofflight.go v/essay/Dictionary/Cornu/DI18G1.jpg [2] Paul Cornu in his first helicopter in 1907. Note that he is sitting between the two rotors, which rotated in opposite directions to cancel torque. This helicopter was the first flying machine to have risen from the ground using rotor blades instead of wings.

[1] Description Uranus.jpg English: NASA photo of Uranus taken by Voyager 2. Caption: This pictures of Uranus was compiled from images recorded by Voyager 2 on January 10, 1986, when the NASA spacecraft was 18 million kilometers (11 million miles) from the planet. The images were obtained by Voyager's narrow-angle camera; the view is toward the planet's pole of rotation, which lies just left of center. The picture has been processed to show Uranus as human eyes would see it from the vantage point of the spacecraft. The dark shading of the upper right edge of the disk is the terminator, or day-night boundary. The blue-green appearance of Uranus results from methane in the atmosphere; this gas absorbs red wavelengths from the incoming sunlight, leaving the predominant bluish color seen here. Images shuttered through different color filters were added and manipulated by computer, greatly enhancing the low-contrast details in the original images. The planet reveals a dark polar hood surrounded by a series of progressively lighter convective bands. The banded structure is real, though exaggerated here. The Voyager project is managed for NASA by the Jet Propulsion Laboratory.

The 3.7 metre diameter high-gain antenna (HGA) is attached to the hollow ten-sided polygonal body housing the electronics, here seen in profile. The Voyager Golden Record is attached to one of the bus sides. The angled square panel below is the optical calibration target and excess heat radiator. The three radioisotope thermoelectric generators (RTGs) are mounted end-to-end on the left-extending boom. One of the two planetary radio and plasma wave antenna extends diagonally left and down, the other extends to the rear, mostly hidden here. The compact structure between the RTGs and the HGA are the high-field and low-field magnetometers (MAG) in their stowed state; after launch an Astromast boom extended to 13 metres to distance the low-field magnetometers. The instrument boom extending to the right holds, from left to right: the cosmic ray subsystem (CRS) above and Low-Energy Charged Particle (LECP) detector below; the Plasma Spectrometer (PLS) above; and the scan platform that rotates about a vertical axis. The scan platform comprises: the Infrared Interferometer Spectrometer (IRIS) (largest camera at right); the Ultraviolet Spectrometer (UVS) to the right of the UVS; the two Imaging Science Subsystem (ISS) vidicon cameras to the left of the UVS; and the Photopolarimeter System (PPS) barely visible under the ISS.

11 YBN [08/25/1989 AD] | 5629) Ship reaches Neptune and sends close-up images. | Planet Neptune |
[1] A picture of Neptune taken by Voyager 2, showing off the Great Dark Spot which has since disappeared from the planet's surface. Original Caption Released with Image: During August 16 and 17, 1989, the Voyager 2 narrow-angle camera was used to photograph Neptune almost continuously, recording approximately two and one-half rotations of the planet. These images represent the most complete set of full disk Neptune images that the spacecraft will acquire. This picture from the sequence shows two of the four cloud features which have been tracked by the Voyager cameras during the past two months. The large dark oval near the western limb (the left edge) is at a latitude of 22 degrees south and circuits Neptune every 18.3 hours. The bright clouds immediately to the south and east of this oval are seen to substantially change their appearances in periods as short as four hours. The second dark spot, at 54 degrees south latitude near the terminator (lower right edge), circuits Neptune every 16.1 hours.

[1] Hitachi Develops a New RFID with Embedded Antenna µ-Chip --Makes Possible Wireless Links that Work Using Nothing More Than a 0.4mm X 0.4mm Chip, One of the World's Smallest ICs-- A New RFID with Embedded Antenna MU-Chip Tokyo, September 2, 2003-Hitachi, Ltd. (TSE: 6501) today announced that it has developed a new version of its RFID µ-Chip embedding an antenna. When using Hitachi's original µ-Chip, one of the world's smallest RFID ICs measuring only 0.4mm X 0.4mm, an external antenna must be attached to the chip to allow external devices to read the 128-bit ID number stored in its ROM (Read-Only-Memory). This newly developed version, however, features an internal antenna, enabling chips to employ the energy of incoming electrical waves to wirelessly transmit its ID number to a reader. The 0.4mm X 0.4mm chip can thus operate entirely on its own, making it possible to use µ-Chip as RFID IC tags without the need to attach external devices. This breakthrough opens the door to using µ-Chips as RFID IC tags in extremely minute and precise applications that had been impractical until now. For example, the new µ-Chip can be easily embedded in bank notes, gift certificates, documents and whole paper media etc. The µ-Chip, announced by Hitachi in July 2001, is one of the world's smallest IC chips at 0.4mm X 0.4mm. The chip data is recorded in read-only memory during the semiconductor production process, and therefore cannot be rewritten, thus guaranteeing its authenticity. Applications of the µ-Chip include a system for managing the SCM materials on sites, and entrance tickets for Expo 2005 Aichi Japan which opens on March 25, 2005. The primary features of this revolutionary µ-Chip are as follows. (1) A RFID IC chip measuring only 0.4mm X 0.4mm with built-in antenna Despite its extremely small size, this µ-Chip has a built-in antenna to permit contactless communications (at very close proximity) with other devices without using an external antenna. (2) No need for special manufacturing equipment The antenna is formed using bump-metalization technology (used to create the electrical contacts of an IC), a process already widely used by semiconductor manufacturers, thus eliminating any need for specialized equipment. (3) Complete compatibility with conventional µ-Chip With ID numbers and support systems that are fully compatible with those of existing µ-Chip, the new chip is fully compatible with all systems that use current µ-Chip technology. Hitachi plans to develop numerous markets for this chip that take full advantage of its outstanding features. Embedding the chip in securities, identification and other valuable documents such as vouchers offers a highly sophisticated means of preventing counterfeiting. Another high-potential application is agricultural products, where the chips can help ensure the safety of food by providing traceability of ingredients. Additionally, the chips can be embedded in business forms to automate logistics systems and many other business processes.

[1] Credit: Zettl Research Group LBNL, University of California, Berkley Electric Drives - Special Purpose Motors (Description and Applications) Motor Construction Special purpose designs have been developed to solve a wide range of drive problems. Some common examples are included here. Integrated Starter Generator (ISG) The electronically controlled integrated starter generator used in mild hybrid electric vehicles (HEVs) combines the automotive starter and alternator into a single machine. The conventional starter is a low speed, high current DC machine, while the alternator is a variable speed 3 phase AC machine. The ISG has four important functions in a hybrid vehicle application It enables the ''start-stop'' function, turning off the engine when the vehicle is stationary saving fuel. It generates the electrical energy to power all the electrical ancillaries. It provides a power boost to assist the engine when required, permitting smaller engines for similar performance. In some configurations it recuperates energy from regenerative braking. In a typical implementation (below), the ISG is a short axis, large diameter ''pancake'' shaped switched reluctance machine mounted directly on the end of the engine crankshaft between the engine and the clutch in the gearbox bell housing. Image source Long, Schofield, Howe, Piron & McClelland ''Design of a Switched Reluctance Machine for Extended Speed Operation'' IMEDC June 2003 The ISG is a bi-directional energy converter acting as a motor when powered by the battery or a generator when driven by the engine. The system voltage in a mild HEV is 42 Volts which means that, for the same cranking power as a 12 Volt machine, the starter current can be reduced. Typical power throughput is between 5kW and 15 kW with a possible peak power of 70 kW for cold cranking.. The brushless ISG design eliminates one rotating machine completely as well as the associated commutator and brushes from the DC machine and the sliprings and brushes from the AC machine. The starter solenoid, the Bendix ring (starter gear) and the pulley or gear drive to the alternator are also no longer needed and because of the higher system voltage, the diameter and weight of the copper cabling is also reduced substantially. The savings however come at a cost. The system must be integrated with several subsystems as follows An AC/DC converter to rectify the generator output voltage. A DC/DC converter to supply the vehicle's electrical power system voltages. Power electronics and software to control the ISG current, voltage, speed, torque and temperature as appropriate. An overall energy management system integrated with the vehicle's engine, battery and brakes. Larger versions of this construction are also used in full hybrid electric vehicles. The switched reluctance machine with its simple rotor of inert iron is very robust, able to operate at high speed and to withstand the harsh operating conditions in the engine compartment. History Outer Rotor Motors There are many designs using this construction, mostly for small sizes. Two examples of low power motors are shown below. High power versions are used for ''in wheel'' automotive applications. Inside Out Motor These are permanent magnet motors with the moving magnets arranged around the periphery of a multi pole fixed stator carrying the field windings. Used for automotive drive systems including in-wheel motors. Low power versions used in small cooling fans and direct drive record player turntables. Toroidal Coil Motor This is an ''inside out'' brushless permanent magnet motor with a toroidal wound stator covered by a cup shaped permanent magnet outer rotor. Because of the low inertia and friction free rotor, the toroidal motor is capable of speeds up to 25,000 RPM. Suitable for low power applications it is used for example to drive the polygonal rotating mirrors which are mounted directly on the rotor in laser printers. Linear Motors In most cases the linear motor can be considered as a conventional rotary motor with both the stator and the rotor split and rolled out flat. The same electromagnetic forces apply and these have been employed in similar classes of AC and DC machines. Except for traction motors the travel of the motor armature is usually quite short. Linear Stepping Motors The most common application is the stepping motor. Stator poles are laid out along the track and excited by windings fed from a pulsed DC source. Permanent magnets forming the armature are held in the carriage. The carriage moves along the track in response to pulses sent to the the stator windings in much the same way as the rotor turns in a brushless DC motor. Closed loop control is possible by mounting a position sensor on the carriage. Despite the elegance of the linear motor, linear motion is more often provided by the less expensive and more mundane method of using a rotary stepping motor driving a lead screw. Maglev Traction Motors The principle of the linear induction motor is used to propel high speed Maglev (Magnetic Levitation) trains which float on a magnetic field created by electromagnets in the trackbed under the train . A separate set of trackside guidance magnets is used to control the lateral position of the train relative to the track. Thus the maglev train uses electromagnetic forces for three different tasks, to suspend, to guide and to propel the train. Maglev trains have been developed in several countries of the world using a variety of configurations. Examples of the essential features are described below. Propulsion The train has no onboard motor. Electromagnets in the trackbed are excited in sequence creating a linear rather than a rotating field. By transformer action, the trackbed coils induce currents in coils on board the train which are used to energise powerful electromagnets. The Lorentz force between the trackbed currents and the the onboard electromagnets causes the magnets to be propelled along by the moving field. The principles involved are very similar to those of the induction motor but with the static and moving parts interchanged. See diagram below. For illustrative purposes the track can be likened to a ladder formed by the unrolled squirrel cage rotor of the induction motor. In this case however it is fixed and it supplies the moving field. Currents are induced in the train's electromagnets which are equivalent to the stator poles of the induction motor but in this case the magnets are free to move. In practical designs the trackbed currents are actually provided in a series of individual coils laid along the track. Levitation Various levitation schemes are used. The force holding the train aloft can be created by the magnetic repulsion between the same electromagnets on the track and the onboard electromagnets in the train which are used for propulsion. The train's levitating magnets are powered by direct current supplied by a battery which is kept charged by an induction generator taking its power from the currents induced by the trackbed coils in the onboard generator coils. In the diagram above, when the magnet is directly above the current carrying conductor as shown, the magnetic forces (north and south poles) from the two adjacent current loops cancel out and there is no lift. If however the magnet is moving very quickly over the coils, it will reach a position over like, repulsive, poles (north poles in the diagram) which are displaced from the attractive south poles so that the net effect is a force repelling the magnet away from the track. This is only possible because the current in the trackbed magnets lags the voltage due to the inductance of the windings, creating a delay in the build up of the balanced field by which time the magnet has moved into the adjacent region where there is a net repulsive force. This effect only happens when the magnet on the train is moving at high speed across the trackbed magnets. Thus the train needs to be in motion for this system to work and the train needs wheels for support as it accelerates from rest and when it is slowing to a halt. Alternatively levitation can be provided by separate windings. The train's levitation magnets protrude from the side of the train and run between pairs of vertically separated electromagnets in guideways at each side of the train, rather than in the trackbed. This arrangement creates an attractive force above the train's magnets combined with a repulsive force beneath the train's magnets to provide the levitating force. Guidance For guidance the train uses magnetic fields provided by a separate set of weaker magnets along each side of the train. Similar in principle to the levitation magnets they are used to control the lateral position of the train relative to the track. Excitation of the trackside magnets is arranged such that only the section under the train is active. As the train moves along the track between sections the current to the previous section is switched off and the current to the next section is switched on pulling the train along. This serves the dual purpose of avoiding losses by energising only the section of track directly under the train and at the same time, since the power to the rest of the track is switched off, it provides security against electric shock to anybody near to the track and avoids the possibility of accidentally short circuiting the system by dropping rubbish onto live conductors. Very high armature currents of thousands of amps or more are involved and some designs use high temperature superconductors ( HTS ) in the onboard magnets, cooled with liquid nitrogen or helium to minimise the resistive losses. As might be expected some sophisticated control systems are needed to keep everything on track. History Axial Field Motors Axial field motors have been developed for applications which require short, flat, ''pancake'' construction. Printed Circuit (PCB) or ''Pancake'' Motor The printed circuit motor is an example of an ironless or coreless motor with several unique features. The pancake construction uses an axial magnetic field to achieve the short flat construction. Radial field PCB motors are also possible. Construction The rotor windings are printed, stamped or welded onto a thin, disc shaped glass fibre circuit board which rotates in the air gap between pairs of permanent magnets arranged around the periphery of the disk. The windings fan out in a series of radial loops around the surface of the disk. The magnets are arranged alternatively north and south so that the magnetic fields in the air gaps of adjacent magnet pairs are in opposite directions. The magnets are held in place by two iron end caps in a compact ''pancake'' shaped block to complete the magnetic circuit. Current is fed to the rotor windings via brushes through precious metal commutator segments printed on the disc. Operating Principle Traditional electric motors have a radial magnetic field or flux with the rotor current flowing axially along the length of the rotor. In typical printed circuit motors the construction is reversed. The magnetic field is axial (oriented along the axis of the machine) and the current flows radially from the axis to the edge of the disc and back again. A tangential force on the disk is created by the current passing through the magnetic fields in the air gaps between the pole pairs of the permanent magnets. So that the return current does not cancel out the effect of the outgoing current, the return wire is physically separated or displaced to one side from the outgoing wire by the width of the magnet. In this way it interacts with the magnetic field of the adjacent magnet which is in the opposite direction and thus reinforces the tangential force on the disk. In many ways it is similar to Faraday's 1831disk or homopolar motor which used a single magnet and was driven by a unidirectional current fed by brushes at the centre and on the periphery of the disk. Applications The printed circuit motor is a very compact and light weight design making it useful in confined spaces. Since the rotor does not have drag a lump of iron around, it has very low inertia and can run up to speed very quickly. Because of the many commutator segments and the low current capability of the windings, the PCB motor is only suitable for low power applications and is not suitable for continuous operation. It is however ideal for servo systems and industrial controls and automotive applications such as electric window winders. Micro-motors (Micro-ElectroMechanical Systems - MEMS) Electrostatic Motor The motor shown below is an example of semiconductor manufacturing technology used to fabricate very small mechanical components. It measures 100 microns across, or about the width of a human hair. Similar in principle to a reluctance motor, it depends on electrostatic attraction, rather than magnetic attraction, between the stator and rotor poles. Because the dimensions are so tiny, very high electric fields can be built up with only a few volts between the motor poles. Fan Long-Shen, Tai Yu-Chong and Richard S. Muller 1989 IC-processed electrostatic micromotors Sensors Actuators 20 41-7 Fan L-S, Tai Y-C and R S Muller 1988 Integrated moveable micromechanical structures for sensors and actuators IEEE Trans. Electron Devices The motor is not assembled from individual components. Instead the components are built up on a semiconductor substrate by masking and etching and a mask-less post-processing release step is performed to etch away sacrificial layers, allowing the structural layers to move and rotate. Micromachined micromotors can be monolithically integrated together with the necessary CMOS drive circuits, containing oscillators, frequency dividers and counters, and transistors for the drive circuit all on one silicon chip. Common uses include defense/munitions applications, computer hard drives, optics, sensors and actuators. History Nano-motors (Nano-ElectroMechanical Systems - NEMS) Electrostatic Motor Even smaller motors have been made using nanotechnology. An example is shown below. It consists of a tiny gold slab rotor, about 100 nm square, mounted on concentric carbon nanotubes. The outer tube carries the rotor, driven by electrostatic electrodes, rotating around an inner tube which acts as a supporting shaft. By applying voltage pulses of up to 5 Volts between the rotor plate and stators, the position, speed and direction of rotation of the rotor can be controlled. It measures about 500 nanometers across, 300 times smaller than the diameter of a human hair.

Because the dimensions are so tiny, very high electric fields can be built up with only a few volts between the motor poles. Fan Long-Shen, Tai Yu-Chong and Richard S. Muller 1989 IC-processed electrostatic micromotors Sensors Actuators 20 41-7 Fan L-S, Tai Y-C and R S Muller 1988 Integrated moveable micromechanical structures for sensors and actuators IEEE Trans. Electron Devices The motor is not assembled from individual components. Instead the components are built up on a semiconductor substrate by masking and etching and a mask-less post-processing release step is performed to etch away sacrificial layers, allowing the structural layers to move and rotate. Micromachined micromotors can be monolithically integrated together with the necessary CMOS drive circuits, containing oscillators, frequency dividers and counters, and transistors for the drive circuit all on one silicon chip. Common uses include defense/munitions applications, computer hard drives, optics, sensors and actuators. History Nano-motors (Nano-ElectroMechanical Systems - NEMS) Electrostatic Motor Even smaller motors have been made using nanotechnology. An example is shown below. It consists of a tiny gold slab rotor, about 100 nm square, mounted on concentric carbon nanotubes. The outer tube carries the rotor, driven by electrostatic electrodes, rotating around an inner tube which acts as a supporting shaft. By applying voltage pulses of up to 5 Volts between the rotor plate and stators, the position, speed and direction of rotation of the rotor can be controlled. It measures about 500 nanometers across, 300 times smaller than the diameter of a human hair. UNKNOWN source: http://www.mpoweruk.com/images/n ems.gif |

[1] * original caption: Jet Propulsion Laboratory (JPL) workers use a borescope to verify pressure relief device bellows integrity on a radioisotope thermoelectric generator (RTG) which has been installed on the Cassini spacecraft in the Payload Hazardous Servicing Facility. The activity is part of the mechanical and electrical verification testing of RTGs during prelaunch processing. RTGs use heat from the natural decay of plutonium to generate electric power. The three RTGs on Cassini will enable the spacecraft to operate far from the Sun where solar power systems are not feasible. They will provide electrical power to Cassini on its 6.7-year trip to the Saturnian system and during its four-year mission at Saturn. The Cassini mission is scheduled for an Oct. 6 launch aboard a Titan IVB/Centaur expendable launch vehicle. Cassini is built and managed for NASA by JPL. * date: 18.

The spacecraft is moving out of the plane of the page and to the right (firing to reduce its spacecraft velocity with respect to Saturn) and has just crossed the ring plane. The SOI maneuver, which is approximately 90 minutes long, will allow Cassini to be captured by Saturn's gravity into a five-month orbit. Cassini's close proximity to the planet after the maneuver offers a unique opportunity to observe Saturn and its rings at extremely high resolution.

[1] Description Huygens on Titan.jpg English: This artist's impression is based on images from Huygens landing on Titan. In the foreground, sits the car-sized lander that sent back images for more than 90 minutes before running out of battery power. The parachute that slowed Huygen's re-entry is seen in the background, still attached to the lander. Smooth stones, possibly containing water-ice, are strewn about the landscape. Analyses of Huygen's images and data show that Titan's surface today has intriguing similarities to the surface of the early Earth.

The Japanese robot probe Hayabusa recently approached the Earth-crossing asteroid and is returning pictures showing a surface unlike any other Solar System body yet photographed -- a surface possibly devoid of craters. One possibility for the lack of common circular indentations is that asteroid Itokawa is a rubble pile -- a bunch of rocks and ice chunks only loosely held together by a small amount of gravity. If so, craters might be filled in whenever the asteroid gets jiggled by a passing planet -- Earth in this case. Alternatively, surface particles may become electrically charged by the Sun, levitate in the microgravity field, and move to fill in craters.

[1] Adapted from: Description This picture is an artist's impression showing how the binary star system of Sirius A and its diminutive blue companion, Sirius B, might appear to an interstellar visitor. The large, bluish-white star Sirius A dominates the scene, while Sirius B is the small but very hot and blue white-dwarf star on the right. The two stars revolve around each other every 50 years. White dwarfs are the leftover remnants of stars similar to our Sun. The Sirius system, only 8.6 light-years from Earth, is the fifth closest stellar system known. Sirius B is faint because of its tiny size. Its diameter is only 7,500 miles (about 12 thousand kilometres), slightly smaller than the size of our Earth. The Sirius system is so close to Earth that most of the familiar constellations would have nearly the same appearance as in our own sky. In this rendition, we see in the background the three bright stars that make up the Summer Triangle: Altair, Deneb, and Vega. Altair is the white dot above Sirius A; Deneb is the dot to the upper right; and Vega lies below Sirius B. But there is one unfamiliar addition to the constellations: our own Sun is the second-magnitude star, shown as a small dot just below and to the right of Sirius A.

[1] International Space Station crew members are trained to observe and document dynamic events on the Earth’s surface, such as hurricanes, forest fires, and volcanic eruptions. Their observations provide scientists and the general public a different perspective on these events. Earlier this week, astronauts in the crew of the ISS-5 mission were able to observe Mt. Etna’s spectacular eruption, and photograph the details of the eruption plume as well as smoke from fires triggered by the lava as it flowed down the 11,000-foot mountain. This image is looking obliquely to the southeast over the island of Sicily. A wider view (ISS005-E-19016) shows the ash plume curving out toward the horizon, caught first by low-level winds blowing to the southeast, and to the south toward Africa at higher altitudes. Ashfall was reported in Libya, more than 350 miles away. The lighter-colored plumes downslope and north of the summit (see detailed view, ISS005-E-19024) are produced by gas emissions from a line of vents on the mountain’s north flank. The detailed image provides a three-dimensional profile of the eruption plume. This was one of Etna’s most vigorous eruptions in years. The eruption was triggered by a series of earthquakes on October 27. These images were taken on October 30, 2002. Sicilans have learned to live with Etna’s eruptions. Although schools were closed and air traffic was diverted because of the ash, no towns or villages were threatened by the lava flow. Astronaut photographs ISS005-E-19016 and ISS005-E-19024 were taken on October 30, 2002, at about 11:30 GMT and are provided by the Earth Sciences and Image Analysis Laboratory at Johnson Space Center. Additional images taken by astronauts and cosmonauts can be viewed at the NASA-JSC Gateway to Astronaut Photography of Earth.

[1] Description English: The dazzling stars in Messier 15 look fresh and new in this image from the NASA/Hubble Space Telescope, but they are actually all roughly 13 billion years old, making them some of the most ancient objects in the Universe. Unlike another recent Hubble Picture of the Week, which featured the unusually sparse cluster Palomar 1, Messier 15 is rich and bright despite its age. Messier 15 is a globular cluster — a spherical conglomeration of old stars that formed together from the same cloud of gas, found in the outer reaches of the Milky Way in a region known as the halo and orbiting the Galactic Centre. This globular lies about 35 000 light-years from the Earth, in the constellation of Pegasus (The Flying Horse). Messier 15 is one of the densest globulars known, with the vast majority of the cluster’s mass concentrated in the core. Astronomers think that particularly dense globulars, like this one, underwent a process called core collapse, in which gravitational interactions between stars led to many members of the cluster migrating towards the centre. Messier 15 is also the first globular cluster known to harbour a planetary nebula, and it is still one of only four globulars known to do so. The planetary nebula, called Pease 1, can be seen in this image as a small blue blob to the lower left of the globular’s core. This picture was put together from images taken with the Wide Field Channel of Hubble's Advanced Camera for Surveys. Images through yellow/orange (F606W, coloured blue) and near-infrared (F814W, coloured red) filters were combined. The total exposure times were 535 s and 615 s respectively and the field of view is 3.4 arcminutes across.

[1] Elliptical Galaxy Centaurus A from CFHT Credit & Copyright: Jean-Charles Cuillandre (CFHT) & Giovanni Anselmi (Coelum Astronomia), Hawaiian Starlight Explanation: Why is peculiar galaxy Centaurus A so dusty? Dramatic dust lanes that run across the galaxy's center mark Cen A. These dust lanes are so thick they almost completely obscure the galaxy's center in visible light. This is particularly unusual as Cen A's red stars and round shape are characteristic of a giant elliptical galaxy, a galaxy type usually low in dark dust. Cen A, also known as NGC 5128, is also unusual compared to an average elliptical galaxy because it contains a higher proportion of young blue stars and is a very strong source of radio emission. Evidence indicates that Cen A is likely the result of the collision of two normal galaxies. During the collision, many young stars were formed, but details of the creation of Cen A's unusual dust belts are still being researched. Cen A lies only 13 million light years away, making it the closest active galaxy. Cen A, pictured above, spans 60,000 light years and can be seen with binoculars toward the constellation of Centaurus.

[1] See Explanation. Clicking on the picture will download the highest resolution version available. In the Center of the Virgo Cluster Credit & Copyright: Jean-Charles Cuillandre (CFHT), Hawaiian Starlight, CFHT Explanation: The Virgo Cluster of Galaxies is the closest cluster of galaxies to our Milky Way Galaxy. The Virgo Cluster is so close that it spans more than 5 degrees on the sky - about 10 times the angle made by a full Moon. It contains over 100 galaxies of many types - including spiral, elliptical, and irregular galaxies. The Virgo Cluster is so massive that it is noticeably pulling our Galaxy toward it. The cluster contains not only galaxies filled with stars but also gas so hot it glows in X-rays. Motions of galaxies in and around clusters indicate that they contain more dark matter than any visible matter we can see. Pictured above, the center of the Virgo cluster might appear to some as a human face, and includes bright Messier galaxies M86 at the top, M84 on the far right, NGC 4388 at the bottom, and NGC 4387 in the middle.
