The schematic light curves of MUSSES2020J and other typical energetic transients (green and orange points denote the stages that MUSSES2020J was observed by the 8.2-m Subaru and follow-up telescopes, respectively). HSC g, r, and i composite multicolor thumbnail image of the host galaxy is shown in the bottom-right corner. A blue cross indicates the location of MUSSES2020J, which is almost at the nucleus of the host galaxy. (Credit: Kavli IPMU)
A team of astronomers have discovered a mysterious short-duration astronomical event, or transient, that is as bright as a superluminous supernova, but evolving much faster, reports a study in The Astrophysical Journal Letters published on July 12.
The universe is full of energetic transient phenomena, astronomical events that occur over a sho...
