Earth’s core isn’t just a boring, featureless ball of metal, it turns out. A recent study used seismic waves from earthquakes to make a 3D model of the center of our planet, ...

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 ...

Scientists say they’ve confirmed Earth’s inner core has been slowing down. Here’s what it could mean — and why the topic has ...

Earth's core is the hottest part of the planet, equivalent to that of the Sun's surface. The core is buried around 5,180 kilometres deep inside the Earth and consists mainly of iron and nickel.

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.

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 ...

Around 1,800 miles beneath your feet lies a giant, blazing-hot ball of metal. It's the innermost part of our planet, Earth's core. It has a profound impact on your life, though none of us can even ...

Behind the expedition to the Earth's mantle 04:06. Earth's inner core, a hot iron ball the size of Pluto, has stopped spinning in the same direction as the rest of the planet and might even be ...

Earth’s iron-rich inner core may owe some of its surprising softness to the motion of atoms, suggest experiments with iron at high temperature and pressure coupled to AI simulations ...

Earth’s Core Might Contain Hidden Helium That Doesn’t Come From This World. Under that much pressure, it turns out that a few rules can, in fact, be broken.
