Johns Hopkins researchers may have identified a compelling clue in the ongoing hunt to prove the existence of dark matter. A ...

Looking towards the central region of the Milky Way, there is an unexpected surplus in the most powerful light that exists: ...

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly ...

All three versions of AstroPix sensor chips are on display from the oldest on the left to version 3 on the right. Version three, which began testing in April 2023 has bigger pixels and improved ...

Gamma-ray spectroscopy is a vital analytical technique employed in identifying and quantifying radioactive nuclides, while artificial neural networks (ANNs) have emerged as robust computational tools ...

NASA is preparing to launch the ComPair balloon-borne science instrument from Fort Sumner, New Mexico, to test innovative technologies for detecting gamma rays, the most energetic form of light.

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 ...

In January 2019, researchers detected gamma-ray burst (GRB) 190114C. They caught this quick explosion right in the act and observed the most energetic photons ever seen from a gamma-ray burst. This ...

An experiment on the side of an extinct volcano in Mexico involving gamma rays is helping scientists answer a fundamental question in physics: Is the speed of light the same throughout the universe?

Two eruptions of gamma rays from exploding stars in far-off galaxies have pelted Earth with the highest-energy photons yet detected from one of these explosions. The shower of light particles reveals ...

NASA sent a retired Cold War spy plane on a storm-chasing mission, and it discovered that big thunderstorms are very radioactive. Large thunderstorms produce so much gamma radiation that the clouds ...
