... The Large Magellanic Cloud is a Dwarf Irregular galaxy in orbit around our own Milky Way. It is a large object, several degrees in size, and easily visible to the unaided eye in Southern Hemisphere skies. The LMC is located in the constellation of Doradus at about 5h30m Right Ascension, -68 degrees Declination, and lies at a distance of roughly 50 kiloparsecs (160,000 light years) from Earth. ...

... Rings of Neptune . ... Methane gives Neptune its blue cloud color. Neptune is a dynamic planet with several large, dark spots reminiscent of Jupiter's hurricane-like storms. ... One of the great cloud features, dubbed the Great Dark Spot by Voyager scientists, can be seen toward the center of the image. ... This Voyager 2 image has been processed by computers so that both the clouds' structure in the dark regions near the pole and the bright clouds east of the Great Dark Spot are visible. ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...

B?rbel Koribalski (ATNF) + HIPASS and ZOA teams . The properties shown below were derived from the measurd HI properties. Displayed here are the Local Group velocities of all sources from -300 to +8000 km/s (bins are 100 km/s). Displayed here are the distances of all sources (assuming Ho = 75 km/s/Mpc). ... Displayed here are the HI masses of all sources (assuming point source distribution). Extended galaxies and pairs/groups need to be re-measured. ...

We report on recent observations of molecular clouds in the tidal Magellanic Bridge; specifically, the Ы?kpc-long, tidally extended "tail" of the Small Magellanic Cloud. In particular, we identify an unusually high 12CO(3-2)/12CO(1-0) ratio of 2-3 to 1, toward one of the clouds, suggesting a warm and dense molecular material associated with imminent or current formation of stars. ...

What will happen when the fragments hit Jupiter? ... All the fragments will enter Jupiter's atmosphere at an angle of 42 degrees from the vertical and impact near a latitude of 44 degrees south, but on the back side of the planet as seen from Earth (about 10 degrees in longitude behind the edge of Jupiter, as seen from Earth). ... Any body moving through an atmosphere is slowed by atmospheric drag, by having to push the molecules of that atmosphere out of the way. ...
