Baby Black Hole dicovered

NASA said yesterday at a press conference that the Chandra space observatory appears to have found the youngest black hole yet found. The black hole should be a baby at the tender age of 30 years.

The Black Hole was formed after the supernova, SN 1979C. The star had a mass 20 times greater than our Sun. The supernova was detected in 1979 in the galaxy M100, which is located 50 million light years away from Earth. The Supernova actually took place some 50 million years ago, but as the light took that long to reach us, we only saw 30 years ago. So, looking for the same site now, we see what looks like a black hole young, 30 years - since we saw the supernova until today (actually, the black hole is 50 million years, but the "light "that surrounds it takes time to get to us). Look for objects in space, you see them as they were when the light left them, and not as they are "now" (When looking at the sun, for example, always see the sun as it was eight minutes before).
