Scientists have uncovered a previously unknown doughnut-shaped region within Earth's outer core, offering new insights into the dynamics of the planet's magnetic field. Located thousands of kilometers ...

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 ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

ANU geophysicist Professor Hrvoje Tkalčić says that the dynamics of Earth's magnetic field is an area of strong interest in the scientific community. A doughnut-shaped region thousands of kilometres ...

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

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

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 ...

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

The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it is ...

Earth’s magnetic field nearly collapsed long ago. What saved it explains why life survived and why the planet remains ...

For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps drive both the ...
