Beneath roughly 5,150 kilometers of rock, liquid metal, and extreme pressure, Earth’s solid inner core sits at temperatures ...

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 ...

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

The Earth’s crust is constantly rewritten by volcanoes, erosion, and plate tectonics. New crust is being created while old one is being destroyed all the time. In that sense, the center of Earth is ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

The liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA satellites provided data on the direction of flow, helping scientists gain ...

Here's what you'll learn when you read this story: Because of the magnetic field's immense role in our continued survival, scientists have spent centuries trying to understand the dynamics and ...

Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...
