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

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

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 made a surprising discovery about the Earth's core that is almost like something out of science fiction. A ...

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

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 surprise discovery that one of the lightest elements in the Universe can bind to iron under high pressure to form iron ...

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 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.

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an ...

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.
