Spiraling into A Black Hole
News story originally written on January 16, 2001
Everyone is awed by black holes.
How could there be a thing that just devours all light and matter around it...so that matter can never escape?!? Scientists using observations from the Chandra X-ray Observatory
and the Hubble Space Telescope
have found material spiraling into black holes!
Both teams have shown evidence for event horizons surrounding 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.
This all sounds like something off the sci-fi channel, but in reality, these findings took an awful lot of hard work! Use the links below to learn more about these findings.
