GRB 211211A was an unusual gamma-ray burst. Its initial flare of gamma rays lasted nearly a minute, and it was followed by a kilonova. It doesn’t fit neatly into the two categories scientists typically use for these bursts.

Summary[edit]

Description
English: GRB 211211A was an unusual gamma-ray burst. Its initial flare of gamma rays lasted nearly a minute, and it was followed by a kilonova. It doesn’t fit neatly into the two categories scientists typically use for these bursts. As shown in this illustration, some researchers think this event could be the result of the merger of a black hole and a neutron star.Credit: NASA’s Goddard Space Flight Center
