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 ...

Particle detector Calculations suggest that millicharged dark matter could be detected by observing its interaction with ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

You may have seen headlines or social media posts talking about a weakening of Earth’s magnetic field, specifically over the South Atlantic. It sounds dramatic, and a little scary. Is Earth losing its ...

If our planet flips and no one’s around to hear it, does it still make a sound? Scientists have managed to put a chilling soundtrack to the flipping of Earth’s magnetic field — and the result is ...

Earth’s magnetic field has been acting restless, with the north magnetic pole racing across the Arctic and the field itself weakening in some regions. Those shifts have fueled viral claims that a ...

The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of ...

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 ...

Earth’s magnetic field feels permanent, but science tells a far more fragile story. Long before modern life emerged, the invisible shield protecting the planet from solar radiation weakened to a ...
