NASA warns of a growing South Atlantic Anomaly weakening Earth’s magnetic shield
Earth's protective magnetic shield has a weak spot, the South Atlantic Anomaly, which is expanding and splitting. This anomaly, driven by changes in Earth's core, poses risks to satellites and spacecraft by increasing radiation exposure. NASA is enhancing monitoring as this dynamic region affects space technology and our understanding of Earth's interior.
