Some of the universe's most energetic and mysterious light shows, long gamma-ray bursts, could be generated after dense dead stars collide to create infant black holes surrounded by a natal disk of ...

Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe's most energetic and mysterious light shows -- ...

Astronomers have caught a cosmic explosion doing something it was never supposed to do, firing off three powerful gamma-ray bursts from the same source within hours. The triple outburst is forcing ...

Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted by long gamma-ray bursts–one of the most energetic events to take ...

"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 ...

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 ...

Gamma-ray bursts were traced to the nucleus of an ancient galaxy about 3 billion light-years away from Earth. By Laura Baisas Published Jun 23, 2023 9:00 AM EDT Get the Popular Science daily ...

A supercomputer simulation of a mere 10 milliseconds in the collapse of a massive star into a neutron star proves that these catastrophic events, often called hypernovae, can generate the enormous ...

It came from somewhere 2 billion light-years away. And when it arrived in October of 2022, the gamma-ray burst lit up the entire ionosphere. Now astronomers are working in a whole realm of “new ...

A flash of high-energy light from deep space has forced astronomers to rethink what they thought they knew about the most violent explosions in the universe. The event, a strange gamma-ray burst that ...

Scientists have pinned down the energy produced by an unusually bright gamma-ray burst detected in 2022, and wow is it a whopper. Reading time 2 minutes The gamma-ray burst, affectionately dubbed ...
