By collecting gamma rays, astronomers are able to see these violent events and can judge exactly how they shape the Universe. For example, some chemical elements are created during explosions in which individual stars blow themselves to pieces. The new chemicals leave gamma-ray fingerprints in the fireball for astronomers to find.

Apr 13, 2017 · The majority is in the form of visible, infrared, and ultraviolet radiation (UV). Occasionally, giant explosions, called solar flares, occur on the surface of the Sun and release massive amounts of energy out into space in the form of x-rays, gamma rays, and streams of protons and electrons. This is called a solar particle event (SPE).
Aug 10, 2016 · Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes. On Earth, gamma waves are generated by nuclear explosions, lightning, and ...
Nov 3, 2024 · gamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. The commonly accepted definitions of the gamma-ray and X-ray regions of the electromagnetic spectrum include some wavelength overlap, with ...

Gamma rays from space are blocked by the Earth’s atmosphere – fortunately for us, because this powerful radiation is lethal. Gamma-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.
