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

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 acquired during the planet’s formation.

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 ...

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

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, ...

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

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

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 ...

Earth-like planets have a thin crust, a large mantle (which contains a lot of molten magma), and a core. Inside these ...

Gold and other precious metals are leaking from Earth’s core into the layers above, eventually making their way up to the surface during the formation of volcanic islands like Hawaii, a new study ...
