## Longest-Ever Gamma-Ray Burst Challenges Existing Theories
GRB 250702B, kterou vidíme z boku a která se nachází v hustě osídleném poli hvězd v centrální rovině naší Mléčné dráhy.Na přiblíženém výřezu ukazují značky přesnou polohu výbuchu poblíž horního okraje tmavé prachové pásky galaxie."” data-width=”910″ style=”max-width: 910px;max-height: 926px”>astronomers are baffled by GRB 250702B, the longest-duration gamma-ray burst (GRB) ever recorded, challenging existing models of thes powerful cosmic events. The burst, detected on July 2, 2023, by the Fermi gamma-ray space Telescope and subsequently studied by the James Webb Space Telescope (JWST), lasted an remarkable 23.5 minutes. This is significantly longer than most GRBs, which typically last seconds
