Record-Breaking Gamma-Ray Burst Lasts Seven Hours, Challenging Astronomers Understanding of Cosmic Explosions Among the universe's most powerful phenomena are gamma-ray bursts — cosmic explosions capable of releasing, in a split second, more energy than the Sun will emit over its entire ten-billion-year existence. Normally, these intense flashes disappear almost immediately, lasting seconds or at most, a few minutes. However, on 2 July 2025 , astronomers detected an event that defied every expectation. Instead of ending quickly, the signal persisted for seven hours , produced three distinct bursts throughout a single day and left behind a glowing aftereffect that continued for months. The moment it was observed, scientists recognized that this was no ordinary gamma-ray burst .

Colossal Black Hole Caught Shredding a Massive Star in Rare Cosmic Event Known as the 'Whippet' A colossal black hole has been caught tearing apart a massive star , likened by scientists to " preparing a snack for lunch ", during observations presented at the American Astronomical Society's annual meeting held from 4-8 January . Astronomers across the globe witnessed the dramatic cosmic encounter , which was reported at the AAS conference in Phoenix, Arizona . The doomed star was described as being ripped apart and consumed piece by piece by black hole's overwhelming gravitational pull .
