More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and ...

Earth’s magnetic field protects the planet from space weather like cosmic radiation and charged particles from the Sun. The ...

Learn about the growth of the South Atlantic Anomaly, a region where Earth's magnetic field has significantly weakened.

Per the ESA, this phenomenon can be best explained by strange behaviors far within the Earth at the boundary where the Earth's liquid outer core meets the rocky mantle layer. This boundary, referred ...

A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

An anomaly that has been weakening the field for the past 11 years is showing signs of ballooning up and splitting apart.

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 ...

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 ...

Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.

Earth's Ediacaran Period, roughly 630 to 540 million years ago, has always been something of a magnetic minefield for ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have ...
