Black hole. Artwork of the spherical region where light is trapped around a black hole,with surrounding interstellar material (blue) being pulled inwards. A black hole is formed when the core of a star collapses under its own weight. This increases its gravitational field to the point where,beyond a boundary known as the event horizon,nothing,not even light,can escape. This leads to its black appearance. Only sufficiently massive stars form black holes,doing so when they have used up the fuel that sustained their nuclear fires. This results in a loss of outwards heat pressure,allowing the total collapse that forms the singularity that is a black hole | |
