Unveiling the Brightest Gamma-Ray Burst in History.

Scientists from the Large High Altitude Air Shower Observatory (LHAASO) have published a groundbreaking study on the gamma-ray burst (GRB) GRB 221009A, an astronomical event resulting from the explosion of a massive star two billion years ago. LHAASO observed the complete high-energy light curve that other experiments have yet to reach, providing a perfect data base for precise tests of theoretical models. The study challenges current theoretical models and provides invaluable data for understanding GRB mechanisms.
