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

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.

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

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.

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.

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

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

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic ...

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