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.
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 ...
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 ...
Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.
Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes 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 ...
Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...
