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.

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 ...

The surprise discovery that one of the lightest elements in the Universe can bind to iron under high pressure to form iron ...

Researchers from Japan and Taiwan reveal for the first time that helium, usually considered chemically inert, can bond with iron under high pressures. They used a laser-heated diamond anvil cell to ...

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 ...

Helium normally has trouble bonding with other elements, but researchers were able to crush atoms of iron and primordial helium together at extremely high heat and pressure to bond them in a ...

Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.

“Before the first stars exploded, there was no water in the Universe because there was no oxygen. Only very simple nuclei ...

Whereas helium-4 is a common product of the decay of radioactive elements, helium-3 comes almost entirely from the initial cloud of dust and gas that formed the solar system. This primordial ...
