Why do astronomers hypothesize that a massive black hole lies at the center of m87? historical records show that a supermassive star at the center of m87 exploded as a supernova, leaving behind a black hole. time-lapse images from space telescopes show stars falling to the center of m87 and then disappearing from view. images of m87 made with powerful telescopes show a well-defined black region devoid of any stars. a very small region at the center of m87 releases an enormous amount of energy.
