Black holes

Black holes are regions of space where gravity is so powerful even light cannot escape their grasp. They can form when stars many times more massive than the Sun burn out and collapse in on themselves.

Supermassive black holes are much larger than black holes that form from the death of a single star and are believed to sit at the centre of some galaxies including the Milky Way. Supermassive black holes may have formed when huge clouds of interstellar gas collapsed, but this is not certain.
