Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat and pressure.

Hidden mega-structures deep inside Earth may have been quietly steering our planet’s magnetic field—and rewriting what we ...

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 ...

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

Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion km into space, the deepest we have ever gone below our feet is just over 12 ...

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 ...

Most of the time, the shape of Earth’s magnetic field is quite similar to that which would be produced by a bar magnet aligned with the planet’s rotation axis. This is what makes a magnetic compass ...

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New ...

Ancient volcanic rocks reveal how two giant hot regions beneath Africa and the Pacific have shaped Earth's magnetic shield.
