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.

More than 75 years after its initial discovery, scientists have created an organometallic molecule containing the transuranium element berkelium. According to a new study, the electronic signature of ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

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

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 ...

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

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 ...
