Simulations suggest that two enormous masses of hot rock have been involved in generating Earth’s magnetic field and giving ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

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

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

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 ...

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

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

The curious minds at What If imagine Earth with Jupiter’s massive magnetic field, exploring how such immense magnetism would affect technology, weather, and life itself.

Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own ...
