Supernova

Supernova

Supernova is a star that explodes and are caused by extremely burst of radiation. Supernova can radiate as much energy as the sun. There are several kinds of supernovas that can be triggered in one or two ways. Either just turning off or turning on the energy through nuclear fusion. At this state is become billion time brighter thna the star. It may also shine throughout the whole galaxy. When it explodes it shoots out heaps of cloud of dust into space. The mass of the supernova may exceed 10 times the mass as to the sun. Supernova is estimated to occur in about every thirty yearsin a typical galaxy. In Miky Way on seven supernovae have occur over the two thousand years. The reason it only occured seven time is because there are two types of suppernovae. Type one and type two. Type one supernovae occur in binary star system in which one of the two stars is small is small and dense star called the white dwarf. The gravitaional pull from the white dwarf attracts the mass form the larger star's companion. By the time it has more than hakf of the mass it will then explode. Type two supernovae is the result of a death of a star that is more massive than the sun. When a star is begins to burn out, its core quickly colllapse and becomes very hot. Nuclear reactions ouccur in this process and heaps of energy is released. Then is exploded to a supernova.
