Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...
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 E ...
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.
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 ...
