For 10 points, name these astronomical entities from which light cannot escape.
These objects have only three externally verifiable properties: mass, charge, and angular momentum, according to the no-hair theorem, and their size can be determined using the Schwarzschild radius. They can be formed following a supernova, and one of them is believed to be at the (*) center of the Milky Way. For 10 points, name these astronomical entities from which light cannot escape.
