Analysis of data from a lightning mapper and a small, hand-held radiation detector has unexpectedly shed light on what a gamma-ray burst from lightning might look like - by observing neutrons ...

New data on the gamma-ray burst "GRB 221009A", observed in October 2022, confirm theoretical models suggesting that these bursts of exceptionally intense electromagnetic waves generate ...

Researchers have detected a gamma-ray burst outside of the Milky Way that's unlike any previously observed. There's no ...

HAIZI MOUNTAIN, China (AP) — Astrophysicist Cao Zhen opens a steel hatch on a windswept Tibetan Plateau and climbs down a ladder into inky darkness. His flashlight picks out a boat floating on a pool ...

For nearly two decades, astrophysicists have believed that long gamma-ray bursts (GRBs) resulted solely from the collapse of massive stars. Now, a team of astrophysicists has uncovered new evidence ...

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 ...

Even though high-quality X- and gamma rays with photon energy below mega-electron volt (MeV) are available from large-scale X-ray free electron lasers and synchrotron radiation facilities, it remains ...

A lead halide material can detect and image single gamma-ray photons with both high-spatial and high-energy resolution ...

For a few seconds every day, Earth is bombarded by gamma rays created by cataclysmic explosions in distant galaxies. Such explosions, similar to supernovae, are known as ‘gamma-ray bursts’ or GRBs.
