Astronomers detect first emission line from brightest GRB

Astronomers have detected the first high-confidence emission line from a gamma-ray burst (GRB), specifically the BOAT (Brightest Of All Time), observed in October 2022. This emission line, linked to matter-antimatter collisions, has a statistical significance of one in half a billion. The spectral emission lasted about 40 seconds, peaking at 12 MeV, marking a significant milestone in GRB research after 50 years of study.
