The 7-Hour Gamma Ray Burst That Broke Physics

A telescope recorded a 7-hour cosmic explosion — something no known object in the universe should be able to do.

On July 2, 2025, NASA's Fermi space telescope detected a gamma-ray burst that wouldn't stop. Three separate explosions over seven hours. X-rays arriving a full day before the gamma rays. The second most powerful burst ever recorded — from a galaxy 8 billion light-years away. Five telescopes pointed at the same patch of sky, and scientists still can't agree on what they saw.
