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.

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 ...

In their view, inorganic molecules might have reacted due to energy from the Sun or lightning strikes to form life’s building ...

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

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

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

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 ...

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

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

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

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