Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven by dynamic processes deep within the planet’s core. Drawing on 11 years of magnetic field data collected by the European Space Agency’s Swarm satellite constellation,

Over 40,000 years ago, Earth’s magnetic field underwent a full reversal, a rare phenomenon in which the North and South magnetic poles switched places. Now, using satellite data and ground-based magnetic records,

As the iron and nickel inside our planet shift, so does Earth's magnetic field, meaning the North (and South) Poles are also constantly on the move. Recently, the position of the magnetic North Pole was officially changed, as it continues its shift away from Canada and towards Siberia.

Earth's magnetic field is crucial to keep its inhabitants safe and protected from harmful solar radiation. However, the geomagnetic field does not remain steady, and the magnetic north does not coincide with true north,

It was one of the strongest geomagnetic storms in decades, traveling towards Earth at over 1 million miles per hour. And yet, it wasn't much of a show for NorCal.

The sun sure has woken up this week, unleashing a powerful X-class solar flare on Jan. 18 that hurled a colossal, fast-moving coronal mass ejection (CME) directly toward Earth. That CME has now arrived, triggering severe (G4) geomagnetic storm conditions far earlier than initially forecast.

Particles from Earth’s atmosphere have been carried into space by solar wind and landing on the moon for billions of years, mixing into the lunar soil, according to a new study.

Skies across the UK were lit up in hues of green and pink by the Northern Lights on Monday evening. The natural phenomenon - known as the Aurora Borealis - is the result of solar eruptions sending particles towards the Earth and interacting with particles in the atmosphere.

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 weak region, is expanding, the north magnetic pole ...
