							A black hole is a place in space where gravity pulls so much that even 
light can not get out. The gravity is so strong because matter has been 
squeezed into a tiny space. This can happen when a star is dying.Because no light can get out, people can't see black holes. They are 
invisible. Space telescopes with special tools can help find black 
holes. The special tools can see how stars that are very close to black 
holes act differently than other stars.

							Black holes are the cold remnants of former stars, so dense that no matter—not even light—is able to escape their powerful gravitational pull.
