Scientists have spotted something firing out “cosmic bullets” into space at nearly the speed of light. The culprit: a supermassive black hole that’s waking up and turning into a quasar… with deadly consequences for its entire galaxy. In this video, we’ll find out how a black hole can kill a galaxy, and whether we should be worried for our own.
