Astronomers Detect High-Energy Gamma Rays from Afterglow of Long Gamma-Ray Burst | Astronomy – Sci-News.com
Astronomers using the High Energy Stereoscopic System (H.E.S.S.) have observed the afterglow of GRB 190829A, a nearby long gamma-ray burst.
Long gamma-ray bursts are bright flashes of extragalactic gamma rays produced during the collapse of a massive star. A gamma-ray burst itself lasts only a few seconds but is followed by an afterglow that can persist for hours or days.
