Gamma-ray bursts, powerful glares of high-energy that wash through the Universe once every day or so are, for a brief time, the brightest objects in the gamma-ray sky. ESA’s Integral gamma-ray ...

Add Yahoo as a preferred source to see more of our stories on Google. The orange dot at the center of this image represents a powerful explosion that repeated several times over one day. - A. Levan, A ...

A strange gamma-ray explosion that fired off repeated bursts from the same patch of sky over roughly seven hours has now been traced to its likely cause: a black hole ripping apart a star that strayed ...

This breakthrough, initiated by first-year B.Sc. students, may prove key in finally discovering the origins of these mysterious bursts. The result is now published in Astrophysical Journal Letters.

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film version of ...

NASA astronomers recently spotted a burst of radiation that was quickly crowned the "BOAT": the brightest of all time. The source of the radiation, which NASA said "swept through the solar system" on ...

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.

When a distant galaxy briefly outshines everything around it in high-energy light, astronomers usually know which playbook to reach for. Gamma-ray bursts tend to fall into familiar categories, either ...

Down here at the bottom of our ocean of air, it’s easy to get complacent about the hazards our universe presents. We feel safe from the dangers of the vacuum of space, where radiation sizzles and ...

NASA has confirmed that on October 9, 2022, our solar system was struck by a gamma-ray burst originating 1.9 billion light-years away that was brighter than any since the beginning of human ...

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 ...
