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 ...

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

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

Consequently, even though it is one of the closest stars to Earth, such that its light takes only six years to get here, it ...

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 ...

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 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 ...
