Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

Astronomers have detected a gamma-ray burst (GRB) like none other. GRB 250702B was longer than any ever observed and repeated ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

Gamma-ray bursts (GRBs) are among the most powerful explosions in the universe, second only to the Big Bang. The majority of these bursts are observed to flash and fade within a few seconds to minutes ...

By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

For as long as people have watched storms roll across the sky, lightning has inspired awe and fear. You can see the flash and ...

Gamma-ray detection and analysis techniques have become indispensable in both basic and applied nuclear research. Modern systems utilise semiconductor detectors – notably high-purity germanium (HPGe) ...

Gamma-ray detectors constitute an essential tool in many scientific and industrial applications, ranging from environmental monitoring and nuclear medicine to safeguards verification. Central to their ...

Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to create compact gamma-ray sources that are simultaneously brighter, sharper, ...
