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

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s ...

The iron-rich core at the centre 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, ...

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 ...

New research reveals that carbon made it possible for Earth’s molten core to freeze into a solid heart, stabilizing the magnetic field that protects our planet. Without it, Earth’s deep interior — and ...

Our planet's core is rich in gold that can leak out into the mantle, and in some cases, end up in volcanos on the surface, according to a new study. When you purchase through links on our site, we may ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...
