Gama radiation bursts happen when a giant star has used up of it's fuel (a star's fuel is hydrogen and helium) and the star collapses very quickly.Gamma radiation is the product of radioactive atoms. Depending upon the ratio of neutrons to protons within its nucleus, an isotope of a particular element may be stable or unstable. Over time the nuclei of unstable isotopes spontaneously disintegrate, or transform, in a process known as radioactive decay. Various types of radiation may be emitted from the nucleus and/or its surrounding electrons when an atom experiences radioactive decay. Nuclides which undergo radioactive decay are called radionuclides. Any material which contains measurable amounts of one or more radionuclides is a radioactive material

Gamma ray bursts take position always, and are thoroughly unpredictable. no human being ought to say with any reality that one will take position in 2012 (or the different particular 3 hundred and sixty 5 days). this finished 2012 project is a hoax! Scientists do not assume something out of the classic to take position interior the three hundred and sixty 5 days 2012, or really on the date December 21, except the solstice, which takes position each 3 hundred and sixty 5 days. not one of the "anticipated" happenings for 2012 delay lower than close scrutiny. "Planet X" and "Nibiru" in basic terms do not exist. The Mayan calendar ends a cycle, yet there have been no predictions of the coolest of the international. The solar would not line up with the galactic centre; that is 6 ranges off. No asteroids or comets are easily anticipated to hit Earth. All of those issues replaced into prepare by skill of crackpots as a thanks to promote their books and tv shows, and shamelessly promoted by skill of the history Channel and the discovery Channel. do not take any of it heavily!

That is when a star explodes and sends gamma rays to Earth. That is called a Gamma Ray Burst (GMB).
