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.

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.

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

Scientists have uncovered surprising evidence that helium, a gas long thought to be chemically inert, may actually bond with ...

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 ...

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.

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 ...

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same.
