A research team has produced the first direct experimental evidence that Earth’s iron core traps hydrogen inside nanoscale ...

With an estimated 6 sextillion kilograms of the stuff—that’s 21 zeroes by the way—the Earth’s core is another example of why ...

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

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 ...

The volume of the ocean, its average purity, and the chemical makeup of H₂O allow a simple estimate of the amount of 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 ...

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, ...
