What is a Black Hole? We Asked a NASA Expert
What exactly is a black hole? Well, they are not holes at all, rather incredibly dense regions in space with gravity so strong, not even light can escape.
There are stellar-mass black holes that form when massive stars collapse and explode in a supernova, and supermassive black holes that are millions to billions of times more massive and sit at the centers of galaxies.
Scientists know these cosmic powerhouses shape galaxies and influence how the universe evolves. However, how do supermassive black holes form? That is still one of astronomy’s biggest mysteries. A NASA scientist explains what we know (and do not know) about these cosmic gargantuans.
