Welcome to my blog "Mystery of Galaxy". Today our topic is Supernova. Stars with masses greater than eight times our Sun are rare; they make up less than 1-tenth of 1% of all the stars in the Universe. But these stellar Giants have an enormous effect on the formation of stars around them and create the elements needed to build rocky planets and even life. But in order to do so these stars must die, and when they do, they don't go gently into that goodnight. Instead they go out with a bang.
