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

The magnetized rocks of Earth's crust and mantle, also known as the upper lithosphere, accounts for generating 6 percent of ...

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 ...

The north magnetic pole’s observed locations from 1831–2007 are yellow squares. Modeled pole locations from 1590–2025 are circles progressing from blue to yellow. Credit: National Centers for ...

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 ...

In about every five years, the U.S. National Oceanic and Atmospheric Administration (NOAA) and the British Geological Survey update the World Magnetic Model (WMM). However, the latest update is quite ...

Fish, birds, reptiles, amphibians, and even a few mammals rely on magnetoreception for navigation. But the exact mechanism ...

Clay bricks from the building projects of ancient kings recorded a historical “map” of changes in the Earth’s magnetic field, a new study has found. About 3,000 years ago, for reasons that aren’t well ...

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 ...
