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

Nearly 3,000 kilometers beneath Africa and the Pacific Ocean, two immense rock masses have been quietly influencing Earth’s ...

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of ...

The blobs lie at the base of Earth’s mantle, around 1,802 miles beneath Africa and the Pacific.

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

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

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 ...

Earth’s magnetic field is easy to forget. It doesn’t make noise, it doesn’t flash, and it doesn’t ask for attention. Yet it ...

A team of geophysicists say that an enormous mass shifted deep beneath the Earth’s surface 18 years ago. As detailed in a paper published in the journal Geophysical Research Letters last month, a team ...

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 ...

Two enormous structures that sit at the border between the Earth’s mantle and its core have puzzled scientists for decades, defying reigning theories of how our planet came to be. In a new study ...
