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.

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.

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

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

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 ...

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

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

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

A major scientific breakthrough has settled a decades-old debate about the moon’s interior. Researchers have confirmed that ...

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our ...

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...
