NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...

New research has failed to rule out self-annihilating dark matter as the source of a gamma-ray emission radiating from the heart of the Milky Way.

What would happen if you took the most energetic explosion in the Universe and sent it straight into one of the most powerful ...

The Milky Way’s farthest spiral arms have long been sketched more from motion than measurement. Now three violent explosions ...

A team of astronomers has discovered that the spiral arms of the Milky Way galaxy may stretch further out into space than was ...

New research conducted by an international team of physicists has found that high-energy gamma rays might offer the key to unlocking the mysteries of the sun's magnetic fields. The study, led by the ...

Gamma-ray bursts (GRBs) rank among the most powerful explosions in the universe, releasing immense energy in intense flashes of gamma rays. The most distant GRBs originate from the era when the first ...

Gamma-ray burst GRB 260623A was detected by NASA’s Fermi telescope morning at 12:56 UTC Tuesday, triggering a global ...

GRB 250702B was spotted in July. ESO / A. Levan, A. Martin-Carrillo et al. Astronomers have spotted a gamma-ray explosion unlike any they’ve seen before, with the help of multiple telescopes, ...

Thunderstorms host a rich variety of electrical discharges that span time-scales from microseconds to minutes and produce radiation extending from radio waves up to high-energy gamma rays. Intense ...
