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

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...

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

That is, helium which differs from normal helium, or 4 He, so called because it contains two protons and two neutrons and is continuously produced by radioactive decay. Primordial helium ...

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.

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 ...
