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.

Life on Earth had to begin somewhere, and scientists think that “somewhere” is LUCA—or the Last Universal Common Ancestor.

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 ...

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

Researchers in Western Australia have found the remnants of a nearly 3.5-billion-year-old impact crater – making it the ...

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

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