Ocurence Of Last Supernova

Last supernova occurred in 1604 which was clearly visible with naked eyes on watching with little concentration.Scientists caught this fact by a mistake,they kept tracking the debris of that supernova for years but later on they recognized that it's the debris of explosion.A supernova averagely occurs every 50-100 years in our galaxy and it emits so much light for the moment it explodes that our whole galaxy together emits.The amount of iron atoms that it sends can tear of sun into bits very easily.Supernova occurs in stars that are 1000 times of sun or more.
