A Supernova is a stellar explosion. These occur at the end of a star's lifetime, when its nuclear fuel is exhausted and it is no longer supported by the release of nuclear energy. If the star is particularly massive, then its core will collapse and in so doing will release a huge amount of energy. The Supernova can radiate as much energy as the Sun could emit over its life span. The Supernovae occur about once every 50 years in a galaxy the size of the Milky Way (our Galaxy) and play a significant role in enriching the interstellar medium with heavy elements.
