How are gamma rays formed
WebSeveral models for the origin of gamma-ray bursts postulated that the initial burst of gamma rays should be followed by afterglow: slowly fading emission at longer wavelengths created by collisions between the burst … WebGamma-ray telescopes in space give evidence for the processes that made the Universe habitable. When a massive star has used up its hydrogen fuel, it ends in a supernova explosion, emitting gamma rays. During this explosion, radioactive elements are formed and ejected into space, decaying or combining to form the other elements.
