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 ...

A dramatic shift in Earth’s magnetic field occurred roughly 41,000 years ago during what scientists now call the Laschamps Event. Recent studies, including a detailed analysis presented at 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 ...

Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in the final phase have now moved on to launching their satellites within the ...

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 ...

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 ...

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

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

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 ...
