Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

Earth’s magnetic north pole has shifted toward Russia, prompting updates to GPS and navigation systems worldwide. Scientists track this invisible movement to keep technology accurate.

Far above the South Atlantic, Earth’s magnetic shield is thinning into a vast, lopsided bruise that now sprawls across an area comparable to nearly half of Europe. This weak patch, known as the South ...

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 dramatically flipped roughly 41,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Nov 28, 2025, 07:59am EST Map of the strength of the Earth's ...

So the magnetic north pole is drifting away from Canada toward Russia. This continued in the year just passed, and the newest ...

In 2024, researchers transformed readings of an epic upheaval of Earth's magnetic field flipping 41,000 years ago into an eerie, auditory experience. Now a team containing some of those same ...

Researchers have discovered there was an anomaly in Earth's gravitational field between 2006 and 2008, potentially caused by a mineral shift deep within Earth's mantle. GRACE satellites detected a ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...
