NASA warns of a growing South Atlantic Anomaly weakening Earth’s magnetic shield |– timesofindia.indiatimes.com

Earth’s magnetic field acts like a protective cocoon, shielding the planet from harmful charged particles racing in from the Sun and deep space. But over the South Atlantic, that shield has developed an unusually weak patch known as the South Atlantic Anomaly. Recent observations show that this anomaly is not only expanding but also shifting, raising concerns for satellites, spacecraft and scientific instruments that pass through the region. While everyday life on the ground remains unaffected, the anomaly’s rapid evolution is prompting NASA researchers to issue stronger warnings and step up monitoring.
