New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, reversing its spin, is weirdly textured, and contains an unusual state of ...

This superionic state of matter would neatly explain some unusual behavior in the core, such as the way it slows certain waves, and measurements that suggest it's squishy like butter rather than rigid ...

Earth’s inner core has both changed its relative rotation rate and deformed in the past few decades, according to an analysis of seismic waves recorded when the inner core occupied the same relative ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. When you purchase through ...
