A black hole is the result of a star that is at least 25 times the mass of the Sun, dying. When these giant stars die, they blow up in a powerful explosion called a supernova. A supernova’s explosion makes a star’s outer layers to shoot out into space. As this happens, the star’s heavy core pulls the rest of the star inward, which causes the star to collapse. The collapse is caused by the core’s extreme gravity, and, as these enormous stars contain a lot of mass, their gravitational pull is extreme. After a supernova, a star’s core is so compact, and its gravity is so strong that the core gets crushed into a miniscule point. Thus, the star becomes a black hole.
