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.

BEIJING -- China's cosmic ray observatory has detected ultra-high-energy gamma-ray radiation from the tail region of a pulsar, indicating a robust particle acceleration process in this area ...

Shrouded in mystery for decades, gamma-ray bursts are the brightest explosions since the Big Bang and emerge from only the most violent cosmic events.

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

A Chinese state-owned nuclear company said it has started mass production of the world’s first chip that can detect X-ray and gamma radiation, in the latest sign of China’s unrelenting efforts ...

Gamma-ray emission from the Sagittarius dwarf spheroidal galaxy due to millisecond pulsars. Nature Astronomy , 2022; DOI: 10.1038/s41550-022-01777-x Cite This Page : ...

GCSE; CCEA Double Award; Radioactive decay and half-life - CCEA Gamma ray. Radioactivity was first noticed by French physicist, Henri Becquerel, in 1896, when he observed that some photographic ...

The team observed around 500 gamma-ray glows and 130 terrestrial gamma-ray flashes (TGFs) during 10 flights in 2023. Additionally, they identified 24 instances of a new type of radiation dubbed ...

Once ionized, the molecule is unable to absorb any ultraviolet radiation, temporarily exposing Earth to more of the sun’s damaging rays. Gamma ray bursts have been known to ionize molecules at ...

Called a gamma-ray burst (GRB), the massive explosion emitted flares of high-energy X-ray and gamma radiation and was likely spurred by a gigantic star’s collapse, according to Inverse’s Kiona ...
