1. Phil Plait's Bad Astronomy: Bitesize Astronomy
... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... 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. ...

5. Dust disk around a black hole in galaxy NGC 7052
... HUBBLE UNCOVERS DUST DISK AROUND A MASSIVE BLACK HOLE . Resembling a gigantic hubcap in space, a 3,700 light-year-diameter dust disk encircles a 300 million solar-mass black hole in the center of the elliptical galaxy NGC 7052. ... Because the jets in NGC 7052 are not perpendicular to the disk, it may indicate that the black hole and the dust disk in NGC 7052 do not have a common origin. ... NGC 7052 is located in the constellation of Vulpecula, 191 million light-years from Earth. ...

These Hubble Space Telescope images reveal a set of bizarre, greenish, looping, spiral, and braided shapes around eight active galaxies. These huge knots of dust and gas appear greenish because they are glowing predominately in light from photoionized oxygen atoms.Each galaxy hosts a bright quasar that may have illuminated the structures. ... Material falling into the black hole was heated to a point where a brilliant searchlight beam traveled into deep space. ...
