When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes back on Earth can detect them. Studying these pulses, which can also come ...

Astronomers are trying to determine what caused a series of gamma-ray bursts, the most powerful explosions in the universe, ...

A gamma ray burst (GRB) unlike anything we detected before has released some of the most powerful photons in the universe four times in the course ... Both these events destroy the source, making the ...

Two neutron stars begin to merge in this artist’s concept, blasting jets of high-speed particles. Collision events like this one create short gamma-ray bursts. Credit: NASA’s Goddard Space Flight ...

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.

"Our findings, which connect observations with underlying physics, have unified many unresolved mysteries in the field of gamma-ray bursts." When you purchase through links on our site, we may earn an ...

A tremendous cosmic explosion 2.4 billion light years away temporarily changed the electric field in Earth’s ionosphere (the electrically-charged upper layer of our atmosphere that helps shield life ...

WASHINGTON – A powerful stellar explosion detected March 19 by NASA’s Swift satellite has shattered the record for the most distant object that could be seen with the naked eye. The explosion was a ...
