Recent studies reveal the supernova astronomers new at the time of the explosion shines up to ten times more luminous than supernovae in general. There are six recording a very bright supernova, and can not be explained by the theory of stellar explosions that exist today that the supernova is likely to be grouped in a new type. The study is published in the latest Nature journal.

Supernova explosion occurs when a star with a mass at least ten times the mass of the Sun reaches the end of his life. At that time, the dying star that releases radioactive material in the form of hot gas to produce a blast of bright light.

Robert Quimby, astronomy researcher at the California Institute of Technology, Pasadena, said that in hundreds of supernovae observed phenomena, there has never been like this type. "We thought we had seen everything, so this finding is not unexpected," said Quimby, who with his team conducted these observations by Samuel Oschin telescope at California's Palomar Observatory.

He noted, supernovae can alter the evolution of the galaxy itself. Because, capable of blowing gas from the supernova origin of galaxies and add content to fill the space between stars in galaxies with grammar heavier elements. "That means the next generation of stars may be different in composition," he concluded.

In a paper published in the June 8, 2011, there are six supernovas have got a new grouping. Four of them are new findings and the other two have been known, but it makes the scientists puzzled, among others, the supernova SN 2005ap with the code, which was found in 2007 and listed as the brightest supernova, as well as SCP 06F6, which was discovered in 2008 because it emits a spectrum that Another entirely by supernovae in general.
