Astronomers Discover New Class of Cosmic Explosions
May 26, 2020 at 11:00 am | News Release

Analysis of two cosmic explosions indicates to astronomers that the pair, along with a puzzling blast from 2018, constitute a new type of event, with similarities to some supernovae and gamma-ray bursts, but also with significant differences.
