One of my favorite scientific twists: Satellites designed to catch nuclear detonations accidentally discovered gamma-ray bursts — the brightest known explosions in the universe. For years, nobody knew whether the signals were nearby, galactic, or cosmological. Now we know they’re tied to collapsing massive stars and black hole formation billions of light-years away. This story dives into the Los Alamos role in that discovery and the birth of high-energy astrophysics.
