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

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are ...

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

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 ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in the direction of Africa over the past decade. When you purchase through ...

Simulations and satellite data reveal that Earth's magnetic field is more complex than scientists had thought. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...
