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 ...

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 ...

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 ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

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 ...

One of Earth’s deepest mysteries lies beneath our feet: the planet’s inner core. Made of iron and nickel, the hot, solid sphere is about 70% the size of the moon. Recent research suggested this dense ...
