NASA and ESA Space Telescopes Lock-in on the Brightest Gamma Ray Burst Ever Recorded

NASA and ESA Space Telescopes Lock-in on the Brightest Gamma Ray Burst Ever Recorded

Astronomers around the world were captivated by an unusually bright and long-lasting pulse of high-energy radiation that swept over the Earth on October 9, 2022. The emission came from a Gamma-Ray Burst (GRB) – the most powerful class of explosions in the universe – and ranks as the most luminous event ever recorded. A Gamma-Ray Burst is a super energetic explosion and this one originated in the constellation Sagitta. The signal of the burst – called GRB 221009A – was picked up by many observatories. Some suddenly noticed an increase in their detection of high-energy emissions. Others were pointed towards the source soon thereafter. The event took place some 1.9 billion years ago and likely indicates the birth of a black hole. The GRB provided an unexpected occasion for different NASA and ESA missions to come together and study the same astronomical event.
