The first gamma-ray bursts were discovered by accident in the 1960's, by spy satellites looking for gamma-rays from secret nuclear bomb tests.

A mysterious gamma-ray burst has left scientists baffled, as it appears to be more powerful and unusual than anything detected before. Gamma-ray bursts are the most energetic explosions in the ...

Dozens of telescopes all over the world are pointing at a patch of sky that gave rise to the most powerful gamma-ray burst ever seen, hoping to shed more light on processes that birth black holes.

Earth just got zapped. On Sunday a gamma-ray burst (GRB), the most powerful class of explosions in the universe, caused a wave of gamma rays and X-rays to sweep over Earth. It was also possibly ...

New research helps resolve the mystery surrounding strange long gamma-ray bursts, suggesting these blasts of high-energy radiation emerge from collisions of neutron stars that birth black holes.

Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022. It has since been dubbed the "B.O.A.T.", the brightest of all time.

For the first time, scientists have caught lightning in the act of unleashing a powerful burst of gamma radiation known as a terrestrial gamma-ray flash (TGF). Researchers at the University of ...

To study the effects of last year’s gamma ray burst on Earth, Dr. Ubertini and his colleagues looked for signals at the top of the ionosphere using data from the China Seismo-Electromagnetic ...

Notably, the method used by this team to measure the gamma-ray-to-neutron branching ratio could also be adapted and applied to other fusion reactions that do not produce neutrons, such as proton ...
