Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of ...

A groundbreaking study,published in Nature Geoscience, has revealed the existence of two massive blobs of superheated rock ...

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

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

The continent-sized blobs are much hotter than the lower mantle, creating a significant temperature gradient in the rocky ...

The blobs lie at the base of Earth’s mantle, around 1,802 miles beneath Africa and the Pacific.

Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...
