Researchers have discovered nine new sources of high-energy photons in the Milky Way, including some of the most energetic gamma rays ever detected. By studying these gamma-ray sources, which all seem ...
NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...

A Black Hole May Have Eaten a Star and Produced the Longest Gamma-Ray Burst Ever Recorded ...
Earlier this year, it was reported that Earth was hit by the brightest gamma-ray bursts seen since the dawn of civilization. Now, a team of astronomers has assigned a value to the energy contained in ...
High altitude: composite image of ASgamma showing the aboveground and underground detectors. (Courtesy: ASgamma) Cosmic gamma rays with energies as high as 450 TeV (10 12 eV) have been observed by the ...
There is no strict theoretical limit on the highest energy of astrophysical gamma rays, so far as I know, but there are some practical limitations. The first is the energy of the particle that ...
When gamma rays hit molecules in the Earth’s atmosphere, they create a cascade of lower energy particles, and these can interact with the water molecules in those big tanks. Sensitive instruments keep ...
The strongest explosions in the universe produce even more energetic radiation than previously known: Using specialised telescopes, two international teams have registered the highest energy gamma ...
Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...
When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown. Using ...
