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

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

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 ...

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

The other stable isotope, accounting for just about 0.000137 percent of Earth's helium, is helium-3, with two protons and one ...

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. Primordial helium from the ...
