Since the discovery of the first X-ray source by Giacconi et al. (1962) and the discovery of Kraushaar et al. (1972) who showed that the Milky Way could be seen in the light of gamma rays, a large number of experiments had been carried out, covering the spectral range from some 10...
known as short gamma-ray bursts (SGRBs). While the gamma rays last mere seconds, the optical light can continue for hours before fading below detection levels (an event called an afterglow). SGRBs are some of the most luminous explosions in the universe with, at most, a dozen detected...
(Image credit: NASA/Robert Lea) Though the sun shines across all wavelengths of light, 99% of its light comes in the form of ultraviolet, visible, and infrared radiation. Much higher energy gamma-ray radiation emitted by our star comes from solar flares, the sun's corona, and, to a ...
What would gamma-ray exposure do to you? Hulk and She-Hulk. (Image credit: Marvel Studios) Being exposed to gamma rays has clearly been no walk in the park for Bruce Banner. One minute, he's trying to open a jar of peanut butter; the next, he finds he's destroyed his favorite pur...

This all-sky image, constructed from two years of observations by NASA's Fermi Gamma-ray Space Telescope, shows how the sky appears in gamma-ray light. (Image credit: NASA/DOE/Fermi LAT Collaboration) Gamma rays are a form of electromagnetic radiation, as are radio waves, infrared ...
The high resolution gamma-ray facility GAMS at Institut Laue-Langevin (ILL). It was previously thought that making a lens out of highly energetic light, gamma rays, was impossible. Physicists have created such a lens and think that it will allow the use of gamma-ray optics for medical im...

The remaining photon energy is reemitted as a Compton scatter photon, which may penetrate through to reach the image receptor and expose it. The transfer of part of the energy of a gamma ray photon to an atomic electron of the shielding material. After undergoing Compton scattering, the gamma...
