Key Takeaways on Earth's Inner Core Earth's inner core is solid and blistering hot. For decades, scientists have known ...

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 ...

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

The historic understanding of the earth’s inner core has been called into question by a group of scientists from the Australian National University after analyzing earthquake data.

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

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 elementary school science class, we learned that the Earth has three main layers: the crust, mantle, and the core.In reality, the core—which is over 4,000 miles wide—has two layers: a ...

A billion years may not sound young, but researchers estimating the age of the Earth’s core say it could be between 1 and 1.3 billion years old – which is at the lower end of previous estimates.

The rotation of Earth‘s inner core may have paused and it could even go into reverse, new research suggests. The Earth is formed of the crust, the mantle and the inner and outer cores. The solid ...

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010 , but what that really ...

One promising model proposed in 2023 described an inner core that in the past had spun faster than Earth itself, but was now spinning slower. For a while, the scientists reported, the core’s ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet.
