New supernova likely arose from massive Wolf-Rayet star

They've been identified as possible causes for supernovae for a while, but until now, there was a lack of evidence linking massive Wolf-Rayet stars to these star explosions. A new study was able to find a "likely" link between this star type and a supernova called SN ...
