The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for ...

NASA observed GRB 250702B, a record-setting gamma-ray burst lasting days, likely caused by a black hole consuming a star, ...

NASA has visualized the cataclysm, which is thought to have caused a mysterious eruption of gamma rays captured by telescopes ...

Astronomers at the University of North Carolina at Chapel Hill have helped uncover new clues about the longest-lasting cosmic ...

A seven-hour gamma-ray burst, GRB 250702B, stuns astronomers and hints at powerful new cosmic engines still unknown to science.

Gamma-ray bursts (GRBs) are intense, transient cosmic events, typically originating from massive stellar collapses or mergers of compact objects, which serve as crucial probes for understanding the ...

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.

A team of astronomers including George Washington University physics Ph.D. student Eliza Neights recorded an extraordinary ...

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 ...

This artist's impression shows a kilonova produced by two colliding neutron stars. While studying the aftermath of a long gamma-ray burst (GRB), two independent teams of astronomers using a host of ...
