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 · Learn what gamma-ray bursts are, how they are caused by different cosmic events, and how they affect the universe and Earth. Find out the difference between long-duration and short-duration GRBs, and the brightest ever GRB observed.
Rozbłysk gamma (GRB, ang. gamma-ray burst) – pojawiające się izotropowo na sferze niebieskiej, mniej więcej raz na dobę i trwające od kilku milisekund aż do siedmiu godzin [1], nagłe wzrosty natężenia promieniowania gamma w niewielkim obszarze nieba. Są to najjaśniejsze źródła promieniowania elektromagnetycznego znane we Wszechświecie.
21 lis 2023 · Learn how gamma-ray bursts (GRBs) are the most powerful events in the universe, how they are classified, and what they reveal about the death of massive stars and the formation of black holes. Discover how NASA missions observe GRBs and their afterglows, and how they challenge current theories.
1 cze 2023 · Fifty years ago, on June 1, 1973, astronomers around the world were introduced to a powerful and perplexing new phenomenon called GRBs (gamma-ray bursts). Today sensors on orbiting satellites like NASA’s Swift and Fermi missions detect a GRB somewhere in the sky about once a day on average.
