The longest gamma-ray burst ever recorded did not roar for seconds or even minutes, but for a staggering seven hours, forcing ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

This artist’s illustration, which shows a high-speed jet of material being launched from a source that is embedded in a very dusty galaxy, depicts GRB 250702B — the longest gamma-ray burst that ...

Astronomers have determined what caused the brightest cosmic explosion ever recorded. Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022.

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 ...

Gamma-ray bursts (GRBs) are among the most powerful explosions in the universe, second only to the Big Bang. The majority of ...

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 ...

Gamma-ray bursts (GRBs) are intense, transient cosmic events, typically originating from massive stellar collapses or mergers of compact objects, which serve as crucial probes for understanding the ...
