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.

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).

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 ...

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 ...

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 inner core is around 750 miles thick and made mostly of solid iron. (Research published in July 2023 suggests some liquid iron could still be trapped in the inner core , left there during ...

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.

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.

USC scientists have made a groundbreaking discovery about the nature of Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.
