Scientists have spotted evidence of two huge companion stars that blew up, according to findings reported by international researchers.
The star that formed the Jellyfish nebula may have had a partner star that exploded 100,000 years earlier, the researchers said.
This may be the first known discovery of a binary star system in which both stars have gone supernova.
The Jellyfish nebula may be the scene of two stars going supernova.
