Some of the brightest, longest-lived flares probably come from megastars getting shredded by supermassive black holes, researchers report in the June 6 Science Advances. This new class of cosmic explosions — dubbed extreme nuclear transients, or ENTs — release more energy than any other known transient, an event that changes brightness in the night sky.
