Black hole galaxy view

A black hole is a region in space where gravity is so intense that nothing, not even light, can escape its pull. Formed from the remnants of massive stars collapsing under their own gravity, black holes are characterized by a boundary called the event horizon, beyond which no information or matter can return. They come in various sizes, from stellar-mass black holes to supermassive black holes found at the centers of galaxies, exerting a profound influence on their surroundings through their gravitational effects.
