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.

Life on Earth had to begin somewhere, and scientists think that “somewhere” is LUCA—or the Last Universal Common Ancestor.

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 ...

Researchers in Western Australia have found the remnants of a nearly 3.5-billion-year-old impact crater – making it the ...

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

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

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

Is it possible that dark matter, which makes up 85% of the cosmic matter budget, is simply a collection of primordial black ...

We don’t know for sure, but the answer is inextricably linked to the moment when water first materialized in the cosmos — and ...

Astronomers have found an unexpectedly bright and chemically complex galaxy from the first 300 million years of the ...
