Think Earth is just a static rock? Dive deep, and you'll find a dynamic world where metals leak, water seeps, and its insides ...

A recent groundbreaking study has revealed something truly surprising: Earth’s core may be leaking iron into the mantle. This discovery, which is backed by a 2020 study in Nature Geoscience, ...

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 inner core may have paused and reversed its spin, a new study suggests.; Earthquakes and nuclear blasts can send seismic waves through the mysterious solid-iron core. Those waves hint that ...

For context: the Earth's center is a solid metal inner core surrounded by a liquid metal outer core. It's about 750 miles thick and reaches 9,800 degrees Fahrenheit (or about 5,400 degrees Celsius).

That solid iron inner core of Earth may still hold liquid iron, according to a new study from the University of Utah. Scientists have used seismic waves to research Earth’s inner 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, scientists believe it’s been changing speeds and directions ...

Earth’s core is located below the middle layer called the mantle and the outer layer–or crust. ... The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth.

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.

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. ...
