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.

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 ...

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 ...

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

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

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. Primordial helium from the ...

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...

This method likely prevented the escape of helium during the measurement phase, Hirose said in a statement. This artificially colored image made using a technique called secondary ion mass ...
