NASA_ MASSIVE BLACK HOLE

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. It's formed when massive stars collapse under their own gravity at the end of their life cycle. The boundary around a black hole is called the event horizon. Beyond this point, the escape velocity exceeds the speed of light. Black holes have fascinated scientists and researchers for decades due to their unique properties and effects on surrounding space.
