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 ...

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

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

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

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

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

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

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.

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