NASA tracks a growing magnetic anomaly over the South Atlantic
Far above the South Atlantic, a strange weakness in Earth’s magnetic armor is widening and slowly changing shape, forcing ...
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 ...
NASA tracks the growing South Atlantic Anomaly, revealing weak magnetic fields, potential satellite risks and some insights into Earth’s core dynamics and magnetic field reversals.

This Strange Anomaly is Expanding, And NASA is Tracking It Over the South Atlantic
NASA has been keeping a close eye on a peculiar and expanding anomaly in Earth’s magnetic field, stretching over the South Atlantic. The region, known as the South Atlantic Anomaly (SAA), is growing ...
A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...
More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...
(a) IGRF model magnetic field intensity of 2024-01in the SAA. (b) CSES/HEPP-L measured 2–10 MeV proton fluxes difference (2024-01 minus 2019-01) in the SAA region. (c) NOAA/MEPED p5-90 measured ...
