flag Astronomers detected three unusually long gamma-ray bursts in one day, signaling a mysterious cosmic event.

flag In July 2024, astronomers detected a rare series of three repeating gamma-ray bursts within 24 hours—unlike any previously observed in over 50 years. flag Unlike typical bursts lasting milliseconds to minutes, these lasted 100 to 1,000 times longer. flag First spotted by NASA’s Fermi Gamma-ray Space Telescope, follow-up data from the Einstein Probe, Swift Observatory, and ground-based telescopes confirmed the source in a distant galaxy billions of light-years away. flag The cause remains unknown, with leading theories including a prolonged supernova or a white dwarf torn apart by a rare intermediate-mass black hole. flag Ongoing studies using the James Webb Space Telescope aim to uncover the origin and assess whether such events are extremely rare or part of an overlooked cosmic phenomenon.
