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 ...

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 ...

A Northwestern-led team of astronomers reached for the stars with a recently compiled gamma-ray galaxy database. The public database, known as BRIGHT, or the Broad-band Repository for Investigating ...

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.

Using technology similar to that found in smartphone cameras, NASA scientists are developing upgraded sensors to reveal more details about black hole outbursts and exploding stars — all while being ...

In the 1990s, NASA scientists got an unexpected surprise. While scanning the cosmos for high-energy gamma radiation bursts from supernovas and black holes, they stumbled upon a curious finding.

In a breathless press release, NASA emphasized that their detectors all over the planet picked up on this, including NASA’s Fermi Gamma-ray Space Telescope, the Neil Gehrels Swift Observatory, and the ...

A small, dense star chowing down on its enormous dying neighbor caused a massive explosion that generated some of the highest-energy gamma-rays ever observed for a nova. The nova system, called RS ...
