The gamma-ray burst of Oct. 9 stood out even among the long-firing gamma-ray bursts previously observed, its photons bombarding satellite detectors for about 10 minutes.

Or, alternatively, short gamma-ray bursts could emerge from unstable hypermassive neutron stars before they rapidly collapse to birth black holes, the team says.Using the model in this way will ...

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 ...

Gamma-ray bursts are the brightest explosions the cosmos has to offer, besides the Big Bang—the explosion that happened 13.77 billion years ago that marks the beginning of time.
