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

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

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, ...

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 ...

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 ...

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 ...

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated the composition ...
