For years, NASA has monitored a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the ...

A fast-expanding weak zone in Earth’s magnetic field is drawing the attention of scientists, satellite operators, and geomagnetic modelers worldwide. Known as the South Atlantic Anomaly (SAA), this ...

Far above the South Atlantic, a strange weakness in Earth’s magnetic armor is widening and slowly changing shape, forcing ...

NASA tracks the growing South Atlantic Anomaly, revealing weak magnetic fields, potential satellite risks and some insights ...

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 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 ...

A growing weak spot in the magnetic field surrounding the Earth could lead to satellite malfunction and even cause them to undergo full blackouts, scientists warned in a new study. The Earth’s complex ...

Will the pole shift actually happen? Discover more about Earth’s magnetic poles and how they’ve shifted in the past.
