Ancient rocks show Earth’s magnetic field followed deep heat patterns inside the planet for hundreds of millions of years.

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

A new theoretical study led by researchers at the University of Chicago and Argonne National Laboratory has identified the ...

The magnetic compass is the last unknown sense in migrating animals. For some scientists, the monarch butterfly is leading the way. The magnetic compass is the last unknown sense in migrating animals.

Here’s what you’ll learn when you read this story: It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field.

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...

Here’s what you’ll learn when you read this story: The Earth’s magnetosphere protects life from deadly space radiation, but many aspects of its function remain a mystery. Scientists have long believed ...
