In gamma-ray astronomy, gamma-ray bursts (GRBs) are immensely energetic explosions that have been observed in distant galaxies, being the brightest and most extreme explosive events in the entire universe, [1] [2] [3] as NASA describes the bursts as the "most powerful class of explosions in the universe".

5 paź 2023 · On October 8 at 13:16:59 UT, orbiting satellites detected an initial blast of gamma rays that lasted for hundreds of seconds. The gamma-ray burst happened very far away, yet it deposited energy equivalent to exploding a ton and a half of TNT into the Earth’s atmosphere.
The InterPlanetary Network (IPN) is a group of spacecraft equipped with gamma ray burst (GRB) detectors. By timing the arrival of a burst at several spacecraft, its precise location can be found. The precision for determining the direction of a GRB in the sky is improved by increasing the spacing of the detectors, and also by more accurate ...
7 gru 2022 · Short bursts emit gamma rays for less than two seconds and are caused by mergers of dense objects like neutron stars. Scientists sometimes observe short bursts with a following flare of visible and infrared light called a kilonova.
8 cze 2023 · The most energetic kind of explosion in the universe, a gamma-ray burst can be spotted billions of light-years away. GRB 221009A was so luminous it effectively blinded most gamma-ray instruments in space when it was detected Oct. 9, 2022.
10 sie 2016 · Gamma-ray bursts are the most energetic and luminous electromagnetic events since the Big Bang and can release more energy in 10 seconds than our Sun will emit in its entire 10-billion-year expected lifetime! Gamma-ray astronomy presents unique opportunities to explore these exotic objects.
