When massive stars die, they do not go gently into the night. Instead, they expel most of their mass outward in a powerful explosion called a supernova, leaving behind a glowing cloud of gas and the collapsed remains of the former star. In June 2015, a supernova appeared in the sky over the Southern Hemisphere, and astronomers believe it could mark the death throes of a very unusual star. The supernova, named ASASSN-15lh, was 20 times brighter at its peak than the combined light of the Milky Way galaxy.
