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.

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

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

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 ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

They used a laser-heated diamond anvil cell to find this, and the discovery suggests there could be huge amounts of helium in the Earth's core. This could challenge long-standing ideas about the ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years.

That is, helium which differs from normal helium, or 4 He, so called because ... implications for understanding Earth’s origins. The presence of helium in the core suggests the young Earth ...

NASA’s James Webb Telescope captured direct images of gas giants in HR 8799, revealing their carbon dioxide-rich atmospheres.
