Too Close to a Black Hole (Dec. 7 2010)
What do you think you would see if you looked directly up to a black hole? Pictured above is a computer generated image modeling how strange it would look. The black hole has such a strong gravitational pull that light actually bent towards it which causes some very unusual visual distortions. Every star in the regular frame has at least two bright images, one on each side of the black hole. Near the black hole, you can see the whole sky because light from every direction is bent around and returns back to you. The original background image was taken from the 2MASS infrared sky survey, including stars from the Henry Draper catalog superposed. Black holes are considered to be the densest state of matter, and there is indirect evidence for their existence in stellar binary systems and the centers of globular clusters, galaxies, and quasars.
