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 ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long ...

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.

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

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 ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

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

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

A rare isotope from the early solar system may be locked in Earth's core, revealing insights into planetary formation ...

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...
