These bursts of light and energy can come from things like tangled-up magnetic fields or hiccups in the heated gas disks surrounding black holes. The flares help illuminate researchers’ understanding of the black holes within.

It took about three months to shine at peak brightness and has been decaying in the years since. It likely happened because a large star wandered too close to the black hole and got shredded to pieces. “At first, we didn’t really believe the numbers about the energy,” said study author Matthew Graham with the California Institute of Technology, which operates Palomar.
