Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

Deep inside Earth, researchers see signs that the solid inner core may be arranged in multiple chemical layers far below.

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...
