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 ...

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

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

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

From the outside, Earth doesn't seem to have a lot going on in the hydrogen department… but that doesn't mean it's completely ...

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 ...

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

These chemical oddities may explain why Earth seems to be deficient in certain elements — and could prove useful in catalysts ...

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 ...

The continent-sized blobs are much hotter than the lower mantle, creating a significant temperature gradient in the rocky ...
