2. APOD: January 5, 1997 - Too Close to a Black Hole
... January 5, 1997 . Too Close to a Black Hole . ... Explanation : What would you see if you went right up to a black hole ? ... On the right is the same star field but this time with a black hole superposed in the center of the frame. The black hole has such strong gravity that light is noticeably bent towards it - causing some very unusual visual distortion. In the distorted frame, every star in the normal frame has at least two bright images - one on each side of the black hole . ...

5. Active galaxies and black holes
Black holes . ... Black holes are objects for which the gravitational attraction is so strong that nothing, not even light, can escape from it. ... The material inside a black hole is concentrated into a singularity: a single point of infinitely high density where space and time are infinitely distorted. ... The existence of such black holes has been inferred in cases where the black hole pulls gas of a companion star that orbits around it. ... Gravity's Fatal Atraction: Black Holes in The Universe. ...

7. 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. ...

8. Evidences of supercritical accretion onto black hole in SS433
... SS433 is a close binary system, one star is a supergiant, a second one is a black hole. ... Even a black hole cannot accept such an enormous mass flux, a supercritical accretion disk appears, all the excess gas glows up to several tens of thousands degrees and is ejected off the disk with enormous velocities. ... SAO researchers have found an evidence of the supercritical accretion onto a black hole in SS433, which follows from a brightness variability of the SS433 disk. ...

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. ...

11. (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. ...

Through this process supermassive black holes often deplete the stellar content of galaxy cores. ... On the contrary, the excellent resolution of the Gemini data shows that the core of this galaxy has a light excess incompatible with the theory that it hosts a supermassive black hole. ... today * ATNF | ...

These images, taken with NASA's Galaxy Evolution Explorer (GALEX) and the Pan-STARRS1 telescope in Hawaii, show a galaxy that brightened suddenly, caused by a flare from its nucleus. ... The top left image, taken by GALEX in 2009, shows the galaxy before the flare, when it wasn't visible in ultraviolet light. In the top right image, taken by GALEX on June 23, 2010, the galaxy had become 350 times brighter in ultraviolet light. ...

... The event horizon is the boundary of a black hole) . ... When the supermassive star implodes (collapses under it?s own gravity) a black hole is formed. Many black holes have been found in the centres of galaxies. ... It was thought that black holes don?t give out any energy at all (except when engulfing stars). ... It is thought that as the stars pass near to the centre, they are pulled in by the black hole and forced to remain orbiting around the black hole. ...

... V4641 Sgr is known as a detached binary containing a 9 Msol. black hole and an A0 type companion. ... Spectra of V4641 Sgr were taken by us using SAO 1-m telescope between May 23.972 and 24.002 UT (the orbital phase of 0.35), wavelength range 3900-7500A, resolution 8A, S/N~30-40. ... These observations show essential light excess over the quiet light level seen only in the orbital phases between -0.25 and +0.25 with the maximum value of 0.15 mag in the V band at the black hole inferior conjunction. ...
