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

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into its future. Earth benefits from the presence of a magnetic field ...

The South Atlantic Anomaly (SAA), a known region of Earth’s magnetic field weakness, has been under the observation of the ...

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

For desert ants, Earth’s magnetic field isn’t just a compass: It may also sculpt their brains. Stepping outside their nest for the first time, young ants need to learn how to forage. The ants train ...

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

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