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 helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long ...

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

All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA—and it likely lived on Earth only 400 million years after its formation.

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. Primordial helium from the ...

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 ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

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