For the first time ever, scientists have received mysteriously delayed signals from two supermassive black holes that snacked on stars in their vicinity.
In the first case, a black hole weighing as much as 30 million suns located in a galaxy approximately 750 million light-years away gobbled up a star that passed too close to its edge. Light from the event was spotted in April 2019, but six months later a telescope in Antarctica captured an extremely high-energy and ghostly particle — a neutrino — that was apparently burped out during the feast.
