A 2022 Gamma Ray Burst Was So Powerful, it was Detected by Spacecraft Across the Solar System

Gamma-ray bursts are some of the most powerful explosions ever detected, emitting more radiation than the rest of their host galaxy combined. In October 2022, a gamma-ray burst struck the Solar System and interacted with the heliosphere. This set off charged particle detectors in spacecraft, from Mars to Earth, to the Earth-Sun L1 Lagrange Point. These separate detections allowed astronomers to track the motion of the radiation as it moved through the Solar System and allowed them to determine t...
