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

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

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 ...

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 ...

Tiny bits of Earth’s atmosphere have been drifting to the moon for billions of years, guided by Earth’s magnetic field.

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 ...

A new study reveals that tiny fragments of Earth's atmosphere are transported to and absorbed by the moon via gusts of solar ...

Space is full of radiation. So much radiation, in fact, that the only thing standing between us and our planet being bathed in radioactive energy from the Sun is the Earth's magnetic field. And this ...
