A black hole is a star in which the gravity is
so strong that nothing can escape from it.
When a huge star begins to burn out, it collapses.
A star ten times the size of our sun will shrink into a very small
size. It becomes so dense and the gravitational pull so strong, that
the star actually disappears! Anything that passes close to it in
space will be sucked in and never get out again.
How do astronomers locate black holes? They look
for them indirectly because a black hole pulls in matter from the nearby
stars. As the matter disappears its send outs strong burst of
x-rays. Astronomers look for these x-ray signals, and are able to
locate black holes.
