A gamma-ray burst (GRB) that has confounded astronomers is one of the brightest cosmic light shows in the past 20 years.

New data on the gamma-ray burst "GRB 221009A", observed in October 2022, confirm theoretical models suggesting that these bursts of exceptionally intense electromagnetic waves generate structured, ...

The international CTAO LST Collaboration has released remarkable findings from observations of GRB 221009A—the brightest gamma-ray burst (GRB) ever recorded. The results were published in The ...

The brightest gamma ray burst ever detected recently reached our planet. It's 70 times longer than any other burst we've spotted, and effectively blinded our instruments when it hit. Researchers say ...

A cosmic explosion that announced itself with a modest flash of gamma rays went on to produce one of the brightest afterglows ...

Artist's visualization of GRB 221009A showing the narrow relativistic jets — emerging from a central black hole — that gave rise to the GRB and the expanding remains of the original star ejected via ...

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 ...
