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

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 ...

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

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 ...

Berkeley Lab geochemist B. Mack Kennedy used this mass spectrometer (foreground) to determine helium isotope ratios in samples of surface fluids from the northern Basin and Range. Disclaimer ...

This discovery suggests that Earth's core could harbor vast reserves of helium, particularly helium-3, a rare and primordial isotope. The presence of helium in Earth's core could rewrite the history ...
