As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it is also a ...

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 ...

While many theories have suggested that comets and asteroids brought water to Earth after its formation, a new study proposes ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

Earth's core is rich with gold, and it's leaking out through the mantle and into the crust, new research has found. A new study of isotopes found in the volcanic rock that oozed out from deep under ...

A study published this week in Nature Communications posits that Earth's core holds a lot of hydrogen. The range is from nine to 45 oceans' worth of hydrogen, mostly locked up in the form of iron ...

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

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

The experts can use these findings in their search for life on exoplanets with similar chemical profiles.
