Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external crust, which may cause minute changes in Earth’s rotation and subtly affect the ...

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 ...

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

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

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...

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

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

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 ...
