Gamma-ray bursts, or GRBs — the most powerful class of cosmic explosions — typically last for less than a minute. But astronomers were astonished by one in July, called GRB 250702B, that continued for days! Data from this record-setting burst was captured by several NASA - National Aeronautics and Space Administration satellites and other facilities. Each NASA telescope used its unique capabilities to add to our understanding of this particular GRB. Our Fermi Gamma-ray Space Telescope discovered

🚨The Longest Cosmic Explosion EVER Caught! A black hole just broke the record for the longest cosmic blast we’ve ever seen. 🤯✨ On July 2, 2025, GRB 250702B lit up the universe — a gamma-ray burst that didn’t quit for DAYS. The leading idea? A tiny black hole dove into a stripped “helium star,” ate it from the inside, and fired jets of energy nearly at light speed. Watch NASA’s animation of a star being torn apart from within. 🌌 GRBs happen almost daily — but nothing like this one. 🎥 Credit:
