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.
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 ...
A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.
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 ...

Space.com on MSN'Primordial' helium from the birth of the solar system may be stuck in Earth's coreThe 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.
Experts warn that "something" in the core of the Earth is causing the magnetic pole to shift. North Pole is shifting toward Siberia and raising concern ...
Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.
