ExploraTour: A Peek into the Lives of the Stars
After stars explode they can become black holes. The movie shows a star turning into a black hole.
Black holes are the strangest object in space. They are the inner parts of stars that gravity has squeezed down to incredibly small sizes. The gravity at black holes is so strong that not even light can escape from them. Since no light reaches our eyes from them, they appear blacker than the blackest night and we call them black holes.
