For years, scientists have tried to understand what’s hidden in the Earth. Now, a recent investigation has revealed something surprising: the Earth’s core ...

Scientists suggest that huge reserves of hydrogen inside the Earth may have been key in the formation of water.

An experiment to quantify the amount of the universe’s lightest element in Earth’s core suggests that the planet’s water has ...

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 ...

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 ...

Precious metals may be escaping from the planet’s core. This hotly debated subject could help us understand Earth’s evolution and determine whether life exists elsewhere in the Universe ...

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

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

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 ...

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