When massive stars die, they go out in fiery explosions called supernovas. On rarer occasions, two nearly dead stars collide to create dimmer yet similarly intense kilonovas. On even rarer occasions, the supernovas and kilonovas overlap in a superkilonova—at least, that’s the best explanation at the moment.
