Elusive black hole radiation predicted by Stephen Hawking may have influenced the way the universe took shape after the Big ...

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 ...

New research suggests that the theoretical Hawking radiation generated by black holes may have influenced the early structure ...

Primordial supernovae got the ball rolling a quick hundred million years or so after the start of the universe.

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

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.

University of Arizona astronomers have learned more about a surprisingly mature galaxy that existed when the universe was ...

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 ...

This primordial element was already known to exist inside Earth. Each year, about 4.4 pounds (2 kilograms) of helium-3 leaks out of mid-ocean ridges where the crust is pulling apart and out of ...
