Turbulent black hole gas prevents star formation

Brett Smith for redOrbit.com - Your Universe Online Astrophysicists have suspected that desolate “red and dead” galaxies are only formed by powerful supermassive black holes at the center of these galaxies stripping away all of the...

New images taken by the Hubble Space Telescope of a pair of galaxies experiencing a close encounter have been released.

Halo Clouds Spotted Around Colliding Galaxies

Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...

Robert's Quartet is four different galaxies in the process of colliding and merging. The galaxies reside in the Phoenix constellation approximately 160 million light-years away. Its members are NGC 87, NGC 88, NGC 89 and NGC 92, discovered by John Herschel in the 1830s. The quartet is one of the best examples of compact groups of galaxies. Since such groups contain four to eight galaxies in a very small area, they provide great laboratories for the study of galactic interactions and their...

Irregular Galaxy -- In astronomy, a class of galaxy with little structure, which does not conform to any of the standard shapes in the Hubble classification. The two satellite galaxies of the Milky Way, the Magellanic Clouds, are both irregulars. Some galaxies previously classified as irregulars are now known to be normal galaxies distorted by tidal effects or undergoing bursts of star formation (see starburst galaxy). ----- NASA Click here to learn more on this topic from...

Active Galaxy -- An active galaxy is a galaxy where a significant fraction of the energy output is not emitted from normal stellar populations or interstellar gas. This energy, depending on the active galaxy type, can be emitted across most of the electromagnetic spectrum, as infrared, radio waves, UV, X-ray and gamma rays. Frequently, the abbreviation AGN (Active Galactic Nuclei) is used, since most of the active galaxies emit most of their radiation from a narrow region in their...

Whirlpool Galaxy -- Discovered 1773 by Charles Messier. The famous Whirlpool galaxy M51 was one of Charles Messier's original discoveries: He discovered it on October 13, 1773, when observing a comet, and described it as a "very faint nebula, without stars" which is difficult to see. Its companion, NGC 5195, was discovered in 1781 by his friend, Pierre Mchain, so that it is mentioned in Messier's 1784 catalog: `It is double, each has a bright center, which are separated 4'35". The two...
