GRB (gamma-ray burst)

A gamma-ray burst (GRB) is a brief but extremely powerful flash of gamma rays—the most energetic form of light—originating from distant cosmic events. They typically last seconds to minutes and are thought to result from massive stellar explosions or the collision of neutron stars, which create black holes. These events release vast amounts of energy, briefly outshining entire galaxies. GRBs help scientists understand extreme processes in the universe, such as star death and black hole formation, and they are detected by specialized telescopes sensitive to high-energy radiation.
