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

A bullet-speed experiment reveals that the Earth's inner core may be softer and more dynamic than previously thought.

Recent research has revealed that Earth’s core is undergoing a slowdown in its rotation, a phenomenon that has piqued the interest of scientists around the world. Understanding the causes and ...

A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new constraint on the chemistry of Earth's core, by showing how it was able to ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

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 ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

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 ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...

Cartoon of the Earth with cutaway showing the mantle and inner and outer core. Magnetic field lines produced by the geodynamo extend into space and interact with the solar wind. The iron-rich core at ...
