NASA Missions Study What May Be a 1-In-10,000-Year Gamma-ray Burst

On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT—the brightest of all time. The source was a gamma-ray burst (GRB), the most powerful class of explosions in the Universe. The burst triggered detectors on numerous spacecraft, and observatories around the globe followed up. After combing through all of this data, astronomers can now characterize just how bright it was and better understand its scientific impact.
