A private moon mission planned for 2027 will be the first step towards commercial lunar mining of rare and expensive helium-3 ...

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 diamond anvil crushed iron and helium together under conditions mimicking those inside the Earth, to create a new compound. These compounds remained stable when pressures were reduced.

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 ...

The research is published in the journal Physical Review Letters. During a volcanic eruption there are often traces of what is known as primordial helium. That is, helium, which differs from ...
