Esa Spacecraft Catches Brightest Gamma Ray Burst Ever
A gamma ray burst is an extremely energetic explosion and this one came from the constellation Sagitta. The burst’s signal – called GRB 221009A – was picked up by several ESA observatories. Some noticed a sudden increase in the detection of high-energy emissions, others turned to the source soon after. The event took place about 1.9 billion years ago and likely indicates the birth of a black hole. The EPHIN Energetic Particle Detector on the SOHO spacecraft and the Starless Object Counter on the Sky Mapper instrument on the Gaia spacecraft received a signal at the same time around 13:20 UTC (15:20 CEST) on October 9, 2022....
