The research, published Monday in Nature Physics, opens a new window into the leadup and immediate fallout of stellar self-detonation, information that is normally blown into oblivion before astronomers have a chance to study it.

„There’s a limited time window,“ said study author Ofer Yaron, an astrophysicist based at the Weizmann Institute of Science in Israel, in a Skype interview with Motherboard. Within days, he said, supernova ejecta traveling at the incredible velocity of 10,000 kilometers per second engulf the regions surrounding exploding stars, destroying evidence of the initial collapse.
