... 2001 September 11 . Spiral Galaxy NGC 3310 Across the Visible . ... Explanation: The party is still going on in spiral galaxy NGC 3310. Roughly 100 million years ago, NGC 3310 likely collided with a smaller galaxy causing the large spiral galaxy to light up with a tremendous burst of star formation . ... NGC 3310 spans about 50,000 light years , lies about 50 million light years away, and is visible with a small telescope towards the constellation of Ursa Major . ... About APOD | ...

... September 5, 1998 . The Pulsar Powered Crab . Credit: J. Hester and P. Scowen ( ASU ), NASA . ... Using a stunning series of visible light images taken with the Hubble Space Telescope (HST) , astronomers have discovered spectacular pulsar powered motions within the Crab nebula. Highlights of this HST Crab "movie" show wisps of material moving away from the pulsar at half the speed of light, a scintillating halo, and an intense knot of emission dancing, sprite-like, above the pulsar's pole. ...

... APOD: 2002 September 18- A Sagittarius Starscape . ... Next huge filaments of dark interstellar dust run across the image and block the light from millions of more stars yet further across our Galaxy . The bright red region on the left is the Omega Nebula , an emission nebula of mostly hot hydrogen gas also known as M17 . A small bright grouping of stars near the image center is the open cluster M18 , while the long bright streak of stars just right of center is M24 . ... September 2002 . ...

... Take a few moments to take in all of the wonderful details captured in this new photo of some baby stars in a glowing cloud of gas. ... Here, the gas cloud hasn t been photographed because there are dark clouds called Bok Globules blocking the view. ... This invisibility cloak, though, has a weakness: It fails when astronomers look at the Bok Globules using a special type of telescope that detects infrared light. ... And infrared light can also travel through the dust inside Bok Globules. ...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... Armagh Observatory reports that, if skies are clear on the night of 27/28 September, skywatchers will witness a rare total eclipse of the Moon during the early hours of Monday 28th. ... As the eclipse progresses from penumbral to partial phase, and then towards totality, it is interesting to observe how the dark shadow of the Earth slowly encroaches on the Full Moon until the Moon is nearly completely obscured. ...

... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ... HISA Main ...

... Its perihelion would occur on April 1, 1997, at which point the comet would be only 0.92 astronomical units from the Sun, just within the orbit of Earth. ...

... High-velocity clouds (HVCs) were discovered by Muller, Oort & Raimond (1963) in the 21-cm line emission of neutral, atomic hydrogen. They are gas clouds which are characterised by high radial velocities incompatible with a participation in the rotation of our Galaxy. ... This suggestion was seized by Braun & Burton (1999) who identified 66 compact high-velocity clouds (CHVCs) with positional and kinematic characteristics being compatible with a distribution across the entire Local Group. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... Comet Animation . ... Comet structures are diverse and very dynamic, but they all develop a surrounding cloud of diffuse material, called a coma, that usually grows in size and brightness as the comet approaches the Sun. ... As comets approach the Sun they develop enormous tails of luminous material that extend for millions of kilometers from the head, away from the Sun. ... The evaporated molecules boil off and carry small solid particles with them, forming the comet's coma of gas and dust. ...
