For decades, scientists have puzzled over traces of primordial helium—a rare isotope known as ³He—escaping from volcanic ...

For decades, noble gases like helium have been considered chemically inert, refusing to form stable bonds under normal conditions. But new research challenges this assumption, revealing that helium ...

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 ...

Mining the moon for water, helium-3, and rare earth elements could become a multibillion-dollar industry in the near future, ...

Helium on Earth comes in two stable isotopes. By far the most common is helium-4, whose nucleus contains two protons and two neutrons. Helium-4 accounts for about 99.99986% of all helium on our ...

Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to 20 minutes after the Big Bang, and is calculated to be responsible for the ...

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