An international team of scientists have identified an “extremely energetic supernova from a very massive star” and said it was the biggest explosion ever recorded, according to a study published on Monday. The astronomers believe that the supernova was originally formed from the merging of two massive stars because of the unusually high amount of hydrogen contained in the explosive cloud. Such a phenomenon so far only exists in theory and has never been confirmed through astronomical observations, according to the scientists.
