Researchers at Göttingen University have uncovered new evidence that some of Earth’s most precious metals began their journey far deeper than once thought. Working with volcanic rocks from ocean ...

The intense heat and pressure at the Earth's core, deep beneath the surface, is enough to make diamonds out of carbon, scientists say. Researchers from Arizona State University's School of Earth and ...

To understand the mantle—the largest layer of Earth’s rocky body—scientists drill deep cores out of the Earth. Scientists drilled the deepest core yet and recovered serpentinized peridotite that forms ...

Our Earth is structured sort of like an onion — it’s one layer after another. Starting from the top down, there’s the crust, which includes the surface you walk on; then farther down, the mantle, ...

The inner core of our planet has started spinning slower and slower, new research has revealed Compared to the speed of the Earth's surface, the inner core was previously thought to rotate faster.

History was made this month. No, not another indictment, or a candidate throwing a hat into the presidential race. For the first time, a drill penetrated into the Earth’s mantle and retrieved samples ...

Seismic waves created by earthquakes as they travel through the planet’s interior change speed and direction as they move through different materials. Things like rock type, density, and temperature ...
