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 ...

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

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 mostly been here since the beginning ...

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

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

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 ...

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

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, ...
