“Those are the earliest spectra ever taken of a supernova explosion.”
By Becky Ferreira | MOTHERBOARD
Scientists have snagged the earliest observations of a supernova ever captured, taken only three hours after a dying star began its fatally explosive finale. 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.
But this particular supernova, called SN 2013fs…
