This supernova dominated our skies for weeks, a thousand years ago. It was brighter than Venus and visible during the day, and observers documented it in China, Japan, Europe and the Arab world. We ...

This supernova is one for the record books. A mammoth star explosion known as SN2016aps, which occurred in a galaxy about 3.6 billion light-years from Earth, is the brightest supernova ever seen, a ...
