Superkilonova: Double Explosion Could Be First Ever Seen
A team of astronomers using numerous telescopes, including the W. M. Keck Observatory on Maunakea, Hawaii Island, have discovered a possible superkilonova that exploded not once but twice. The evidence shows this oddball event may be a first-of-a-kind superkilonova, or a kilonova spurred by a supernova. Astronomers have hypothesized such an event, but it’s never been seen before.
