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

New experiments suggest that Earth’s core may store vast hidden reserves of life-essential hydrogen.

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

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle ...

Scientists have estimated that Earth’s core may contain the equivalent of between nine and 45 oceans of hydrogen, making it ...

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 ...

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 ...

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

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 ...

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.

A new scientific revelation reveals that deep in the Earth’s core lies a good amount of hydrogen as well as a large amount of iron. While the iron in the core has always been recognized as dominant, ...
