Gamma-ray bursts (GRBs) were first discovered in the late 1960s by US military satellites. Initially detected as brief flashes of gamma radiation, these events were later understood to be the most energetic explosions in the universe. Originating from supernovae or merging neutron stars, GRBs can outshine an entire galaxy for brief moments. Intensive study continues today to understand their origins and implications in astrophysics.
