There are two main types of gamma ray bursts: short duration and long duration. Besides their time of duration, the main difference between these is their origin. Short wavelength rays come from the fusion of two neutron stars, while long duration rays come from the creation of a supernova. For both, gamma rays are given off due to nuclear instability of atoms.This instability, called the metastable state, causes the nucleus of an atom to release a particle known as a positron. The positron has the same mass as an electron, but the opposite charge. After being emitted from the nucleus, it impacts an electron in a process called annihilation, which results in the release of gamma radiation. This occurs in collisions between other matter and antimatter particles as well, all of which produce electromagnetic radiation.The nuclear instability that causes gamma radiation to occur exists due to magnetic instability in a torus. The torus is a ring of matter produced by the merging of two neutron stars or the collapse of a neutron star into a black hole. It, like its parent star, contains magnetic fields. The torus spins more quickly near the center than near the edge, causing the magnetic fields to become irregularly shaped and unstable.Gamma rays are the most energetic, lowest wavelength type of electromagnetic radiation. They have a high penetrating power, or ability to pass through matter. Scientists normally use crystals to detect gamma radiation in a process known as Compton scattering. The gamma ray scatters the electrons in the crystal, which can then be detected by electrical sensors. Due to the damaging effects of gamma radiation, it is one of the possible causes of the Ordovician extinction, an event that occurred about 444 million years ago. In that extinction, the glaciation of the ocean caused the extinction of many species. A gamma ray burst may have damaged the Earth’s atmosphere enough to cause this cooling. 1102794 https://padlet.com/1102794/rbzqyi2m9olb/wish/245584521 2018-03-23 17:25:43 UTC https://padlet.com/1102794/rbzqyi2m9olb/wish/245584521 Science Mission Directorate.
