The GRBAlpha nanosatellite observed the most powerful cosmic explosion since the beginning of human civilisation
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 and was also observed by the world's smallest astrophysical satellite, GRBAlpha.
