NASA Is Tracking a Vast Anomaly Growing in Earth's Magnetic Field

alternative_right writes: For years, NASA has monitored a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies, stretching out between South America and southwest Africa.

This vast, developing phenomenon, called the South Atlantic Anomaly, has intrigued and concerned scientists for decades, and perhaps none more so than NASA researchers.

The space agency's satellites and spacecraft are particularly vulnerable to the weakened magnetic field within the anomaly, and the resulting exposure to charged particles from the Sun.
