Scientists watched a star explode in real time for the first time ever

Astronomers have watched a giant star blow up in a fiery supernova for the first time ever — and the spectacle was even more explosive than the researchers anticipated. 

Scientists began watching the doomed star — a red supergiant named SN 2020tlf and located about 120 million light-years from Earth — more than 100 days before its final, violent collapse, according to a new study published Jan. 6 in the Astrophysical Journal. During that lead-up, the researchers saw the star erupt with bright flashes of light as great globs of gas exploded out of the star’s surface.
