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. ...

Alternatively, the black holes in the center of Seyfert Type II galaxies might be obscured by a surrounding torus . ... The constant flux and apparent absorption of very specific X-ray colors by cool iron together give evidence that the central black hole in NGC 4388 is seen through a thick torus composed of molecular gas and dust . ...

4. (S-7a) The Black Hole at the Center of our Galaxy
... 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. ...

6. Pink Black Holes: Frequently Asked Questions
... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...

7. http://www.eso.org/public/news/eso1303/kids/
... This beautiful new image shows a glowing cloud of cosmic dust sitting boldly against a backdrop of shining stars. To the naked eye, thick clouds like these appear empty and dark, but some are actually home to the brightest nebulae and hottest young stars in the Universe! Stars are made of gas, so it is no surprise that they are born inside thick, gassy clouds. But the clouds that give birth to stars also block our view of them growing within. ...

8. Hubble Uncovers Dust Disk Around a Massive Black Hole (STScI-PRC98-22) A
... 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 front end of the disk eclipses more stars than the back, it appears darker. ... Despite its size, the disk is 100 times less massive than the black hole. ... The bright spot in the center of the disk is the combined light of stars that have crowded around the black hole due to its strong gravitational pull. ...

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. ...
