Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure ...

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

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

Hydrogen reserves in Earth’s core large enough to supply at least nine oceans may influence processes on the surface today.

Deep beneath the familiar blue of the oceans, Earth may be hiding a far larger sea of potential. New high pressure experiments suggest the planet’s metallic heart could store hydrogen equivalent to ...

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 ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

Billions of years ago, Earth was an uninhabitable rock covered in magma. Scientists are still working to decipher the tale of how it transformed into a blue and green orb teeming with life. However, ...

Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion ...
