A startup company wants to establish mining operations on the moon to extract a rare isotope needed for future quantum ...

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 ...

On Earth, helium comes in two stable isotopes. By far the most common is helium-4, with a nucleus containing two protons and ...

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 ...

Normal helium, which is 700,000 times more common than helium-3, is called helium-4 because it has two protons and two neutrons. Whereas helium-4 is a common product of the decay of radioactive ...
