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...
