Gamma rays are high-energy photons produced by some of the most violent events in the universe. We explore this powerful radiation in more detail here.

Sources emitting gamma radiation with photon energies between 100 GeV and 100 TeV are called very-high energy (VHE) gamma-ray sources, while those with photon energies above 0.1 PeV are known as ...

Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.

In the latest edition of Nature, groundbreaking results about the gamma-ray emissions produced during thunderstorms are presented. These findings show that gamma-ray emission from thunderclouds is ...

Thunderstorms are known to generate gamma rays, the highest energy radiation on Earth. But pinning the burst to a specific bolt is new.

Scientists have pinned down the energy produced by an unusually bright gamma-ray burst detected in 2022, and wow is it a whopper.

Thunderstorms churn up a ‘boiling pot’ of gamma rays A view from a retrofitted spy plane reveals complex emissions of high-energy light ...

The source of a huge burst of radiation from deep space that hit Earth in 2023 likely was one of the rarest and most bizarre objects in the universe: a magnetar.

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT ...

Researchers have used giant lobes of gamma radiation to find that a small satellite galaxy of the Milky Way filled with dark matter, but whose emissions are more likely the result of millisecond ...
