Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

Scientists have uncovered surprising evidence that helium, a gas long thought to be chemically inert, may actually bond with ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an ...

Tectonic plates move, causing strain energy to build up, and that energy eventually releases in the form of an earthquake. As ...

The surprise discovery that one of the lightest elements in the Universe can bind to iron under high pressure to form iron ...

In fact, solid iron at high temperature and pressure could contain ... Mexico who was not involved in the study but studies Earth's core. The findings confirm that helium could stay locked in ...
