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.

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 ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

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

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

Across the street from the Flamingo Visitor Center at the foot of Florida's Everglades National Park, there was once a ...

Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.

Barnard's Star is a small, dim star, of the type that astronomers call red dwarfs. Consequently, even though it is one of the ...

CeraPhi Energy, an energy company pioneering the use of heat from the earth’s core as a source of heating and power, has opened a new office ...

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

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