There was a Supernova explosion in Large Magallen Cloud in 1987. This supernova was quite different from other supernovae. Most supernovae come from red supergiant stars but this one was a blue supergiant. Before only red supergiant like Betelgeuse become supernova. But this one was a blue supergiant like Rigel. How does blue supergiant stars becomes supernovae?
