Geologists discovered ancient rocks in Greenland that preserve the oldest known traces of Earth’s early magnetic field.

The Magnetic Shield That Protects Our Climate Earth is surrounded by an immense magnetic field, called the magnetosphere.

The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years. This has sparked many questions and concerns about the implications of such ...

Simulations and satellite data reveal that Earth's magnetic field is more complex than scientists had thought. Scientists ...

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 ...

Scientists have known for decades that many animals use the Earth's magnetic field for navigation. It's less clear how they do it. A new study suggests earthworms may be a good way to figure it ...

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 ...

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 ...

Many migratory birds use Earth’s magnetic field as a compass, but some can also use information from that field to determine more or less where they are on a mental map. Eurasian reed warblers ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...
