It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... Instead, new evidence obtained using the UK's Infrared Telescope (UKIRT) in Hawaii, spins a different story. Streams of spinning bullets have been discovered. These infrared bullets, moving at prodigious speeds, deposit the spin far away from the birth region'' , stated Armagh Observatory astronomer Dr. Michael Smith. ... Now, using the UK Infrared telescope in Hawaii fitted with sensitive instruments, a team of astronomers have found evidence that the jets of bullets are spinning. ...

... Like a last gasp of breath, Sun-like stars puff away their outer layers of gas at the end of their lives. This gas floats away into space and forms beautiful and striking clouds, which are called planetary nebulae (although they have nothing to do with planets). ... Yet, astronomers looking at 100 planetary nebulae in the bulging centre of our Galaxy, the Milky Way have found that most of the bipolar planetary nebulae in this region are acting in the same, strange, way. ...

... 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. ...
