A supernova is an energetic explosition of a star that generates bursts of radiation throughout the galaxy. This is a very rare event to see by the naked eye let alone an optical telescope. This event happens when the core of a star is changed causing it to explode. The explosion distributes elements throughout the universe to help form new items such as stars and planets. They are more significant than regular nova's. They generate bursts of radiation into the universe. There is 2 types of supernova's. Type I which the star is lacking hydrogen in the spectrum and type II which unlike Type I has strong hydrogen lines in the spectrum. Supernova's play an important role in the universe by helping to form new stars and planets.
