Deep beneath the familiar blue of the oceans, Earth may be hiding a far larger sea of potential. New high pressure experiments suggest the planet’s metallic heart could store hydrogen equivalent to ...

The cycling of water within Earth's interior regulates plate tectonics, volcanism, ocean volume, and climate stability, making it central to the planet's long-term evolution and habitability and a key ...

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

Research shows the Pacific hemisphere is losing heat faster than the African hemisphere. The heat is from Earth’s molten interior, which causes continental drift. Landmass traps more heat than ...

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

Earth’s magnetic field and atmospheric oxygen appear to have moved in sync for half a billion years, pointing to a surprising connection between the planet’s deep interior and life-supporting ...

Hidden mega-structures deep inside Earth may have been quietly steering our planet’s magnetic field—and rewriting what we thought we knew about Earth’s past.

The Earth's magnetic field is responsible for the rotation of both the inner and outer cores, new research suggests. The heat near Earth's core flows at a slower rate than previously thought. The ...
