More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and ...

Satellite data reveal that a weak region in Earth's magnetic field has grown by an area roughly half the size of continental ...

The weak spot, known as the South Atlantic Anomaly, was identified in the 19th century and expanded in recent years.

Per the ESA, this phenomenon can be best explained by strange behaviors far within the Earth at the boundary where the Earth's liquid outer core meets the rocky mantle layer. This boundary, referred ...

The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of ...

A weak zone in Earth’s magnetic field, known as the South Atlantic Anomaly, has expanded at an alarming rate over the past ...

Scientists made these observations using data from the European Space Agency’s Swarm mission, which relies on three identical ...
