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 ...

Earth's magnetic field is crucial to keep its inhabitants safe and protected from harmful solar radiation. However, the ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

A severe G4 geomagnetic storm on January 19, 2026 enabled widespread aurora visibility across multiple continents following the arrival of a fast coronal mass ejection.

A powerful geomagnetic storm caused by an X-class solar flare and a fast-moving coronal mass ejection has disrupted Earth's ...

An unusual reduction in the strength of the Earth’s magnetic field between 591 and 565 million years ago coincided with a significant increase in the oxygen levels in the atmosphere and oceans, ...

Over 40,000 years ago, Earth’s magnetic field underwent a full reversal, a rare phenomenon in which the North and South ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...
