Deep beneath our feet, far below the crust and mantle, Earth’s metallic heart is not as sealed off as geologists once assumed ...

Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust last year, pulling out a treasury of geological goodness. The result ...

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 ...

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 ...

With findings on Earth’s polar extremes and its innermost core, scientists shaped how we look at the planet in 2025 in ...

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 ...

A new study adds evidence to the idea that Earth's inner core is slowing its spin, though still rotating in the same direction as the planet. KATERYNA KON / SCIENCE PHOTO LIBRARY via Getty Images The ...

In 2025, scientists discovered that gold is escaping from Earth's core and the world's oldest rocks may be located in Quebec, ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...

While InSight’s seismometer has been patiently waiting for the next big marsquake to illuminate its interior and define its crust-mantle-core structure, two scientists, Takashi Yoshizaki (Tohoku ...
