Two eruptions of gamma rays from exploding stars in far-off galaxies have pelted Earth with the highest-energy photons yet detected from one of these explosions. The shower of light particles reveals ...
Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted by long gamma-ray bursts–one of the most energetic events to take ...
China’s Large High Altitude Air Shower Observatory (LHAASO)–one of the country’s key national science and technology infrastructure facilities–has found a dozen ultra-high-energy (UHE) cosmic ...
Astronomers have detected the highest-energy light ever seen, streaming in from near the center of the Milky Way. Hundreds of gamma ray signals were detected with ultra-high energies, with the most ...

Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy ...
