ASASSN-15lh is the brightest supernova discovered so far
An article published in the journal “Science” describes the discovery of the supernova ASASSN-15lh, the brightest discovered so far. A team of astronomers led by Subo Dong, of the Kavli Institute for Astronomy and Astrophysics at Peking University, China, studied this explosion that is extraordinary even by the standards of these events: it’s more than twice as bright as the one that held the record, about 200 times brighter than the average supernova, 570 billion times brighter than the Sun, and 20 times brighter than all the stars in the Milky Way put together.
