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 ...

ESA’s Swarm mission reveals the South Atlantic Anomaly has expanded by half the size of Europe since 2014, exposing ...

A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites ...

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 ...

The South Atlantic Anomaly (SAA) is a particularly weak region of Earth’s magnetic field that can cause satellites to ...

Earth’s magnetic field is essential to life on our planet. It protects Earth from cosmic radiation and acts as a shield ...

This expanding anomaly exposes satellites passing over the region to heightened cosmic radiation and charged solar particles, ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

New satellite data show Earth’s magnetic field changing fast, with a growing weak spot over the South Atlantic.

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have ...
