Weird star explosion is brightest supernova ever seen

"Very massive stars like this one were probably more common early in the universe’s history, Nicholl said.

“The nature of those first stars is one of the big questions in astronomy,” Nicholl added. “In astronomy, seeing things further away means looking back further and further in time. So we might actually be able to see the very first stars if they explode in a similar manner to this one. Now we know what to look for.”"
