Spiraling into A Black Hole
News story originally written on January 16, 2001
Everyone likes hearing about black holes.
They are so mysterious! Scientists using the Chandra X-ray Observatory
and the Hubble Space Telescope
have found material spiraling into black holes!
Both teams found what they think to be event horizons around black holes.
Event horizons are the point around a black hole from which nothing (not even light!) can escape! Only black holes have event horizons, so finding an event horizon is finding a black hole.
