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.

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 ...

Scientists have made a surprising discovery about the Earth's core that is almost like something out of science fiction. A ...

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.

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

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

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

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our ...
