Gamma Ray Bursts (GRBs) are extremely energetic explosions observed in distant galaxies. They release intense bursts of gamma radiation, which is the highest-energy form of light. These events can last from milliseconds to several minutes and are thought to occur when massive stars collapse into black holes or when neutron stars collide. GRBs are among the brightest events in the universe and can outshine entire galaxies for a short time. They are detected by space-based observatories, such as the Fermi Gamma-ray Space Telescope, which helps scientists study their origins and the conditions of the early universe.
