New simulations reveal a hidden “ocean of fire” that once existed above Earth’s core, influencing the planet’s internal ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar ...

New simulations reveal that an ancient ocean of magma located above the Earth's core continues to shape the planet's ...

The researchers say the Earth’s true core is iron because of the “ricochets” they uncovered. It’s an intriguing discovery, and one that the paper outlines very well.

Scientists have long wondered what lies at the center of the Earth. New research is putting weight behind a theory that our home planet has a distinct ball of iron within its metallic core.

Earth’s solid iron inner core appears to be spinning at a slower rate than the planet, according to a new study — but no worries, ...

The research could also challenge the idea that the Earth's molten iron core is almost hermetically sealed, study author Dan Shim, a professor of Earth and Space exploration at Arizona State ...

A model of iron atoms on the move in Earth's inner core. The model demonstrates how iron atoms are expected to move about in the Earth’s inner core over 10 picoseconds, or 10 trillionths of a second. ...

Imagine Earth’s inner core — the dense center of our planet — as a heavy, metal ballerina. This iron-rich dancer is capable of pirouetting at ever-changing speeds.

In reality, the core—which is over 4,000 miles wide—has two layers: a liquid outer core and a solid and dense inner core made mostly of iron that actually rotates.

That’s what Earth’s inner core — which starts about 5,300 kilometers below our feet — is like. And it turns out that under these conditions, iron becomes a solid; its atoms stay in one ...

Earth's core is surrounded by a fluid outer core of molten iron and nickel that is 1,500 miles thick. It is located roughly 3,100 miles below the surface and is believed to produce the magnetic ...
