Deep below the Tyrrhenian Sea offshore Italy, scientists drilled into what they thought would be dark mantle rock—and found ...

Computer simulations have uncovered a new manganese compound that could exist deep in Earth’s mantle and may be connected to ...

Helium isotope measurements in hot springs of the Kafue Rift reveal a direct connection with the Earth's mantle, suggesting that the crust has broken and a new plate boundary is forming. The team, led ...

Slow roiling convection currents deep within Earth's mantle, which are associated with the movements of tectonic plates, also deform the material of the mantle itself. Now, a new study in The Seismic ...

Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth’s mantle rather than its crust. Long debated and notoriously difficult to confirm, ...

During mantle overturn, large-scale plumes rise toward the surface, contributing to the formation of the Archean continents. Simultaneously, the temperature at the core-mantle boundary rapidly ...

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 ...

Here’s what you’ll learn when you read this story: 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 ...

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 ...

Two perplexing structures deep inside Earth might be ancient remnants of our early planet. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Two ...

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New ...

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 ...
