Astronomers have spotted the longest gamma-ray burst ever seen, a cosmic explosion that lasted seven hours — and they ...

Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, ...

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

Joint analysis of the GECAM-C and Fermi/GBM observation data on the brightest ever gamma-ray burst (GRB 221009A) reveals the discovery of gamma-ray line up to 37 MeV, the highest-energy gamma-ray line ...

Astronomers have observed the longest-ever gamma-ray burst — a powerful, extragalactic explosion that lasted over seven hours ...

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...
