While famous for devouring anything and everything in its gravitational pull, black holes aren’t constantly destructive. In fact, they often exhibit long periods of dormancy. Astronomers had never witnessed a black hole “wake up” in real time—until now. Researchers have spent the past few years watching a black hole re-awaken roughly 300 million light-years away from Earth. And what they’ve documented challenges prevailing theories about black hole lifecycles. The groundbreaking observations are detailed in a study published on April 11 in Nature Astronomy.
