Researchers at the University of North Carolina at Chapel Hill have contributed to new insights into the most long-lived cosmic explosion ever recorded. The event was a gamma-ray burst that remained ...

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

Data collected using multiple NSF NOIRLab facilities reveal a gamma-ray burst that lasted more than seven hours and originated in a massive, extremely dust-rich galaxy. Gamma-ray bursts (GRBs) rank ...

James Webb has spotted the most distant supernova ever seen, exploding just 730 million years after the Big Bang, offering ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

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 ...

"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 ...

Astronomers have detected a gamma-ray burst (GRB) like none other. GRB 250702B was longer than any ever observed and repeated. The GRB was "unlike anything ever witnessed before," according to the ...

Hundreds of gamma-ray bursts (GRBs) have been recorded as part of an enormous global effort so extensive it 'rivals the catalog of deep-sky objects created by Messier 250 years ago', astronomers say.

The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a ...
