There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

Scientists have detected a surprising amount of a rare version of helium, called helium-3, in volcanic rocks on Canada’s Baffin Island, lending support to the theory that the noble gas is leaking from ...

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

Gold and other precious metals are leaking from Earth’s core into the layers above, eventually making their way up to the surface during the formation of volcanic islands like Hawaii, a new study ...

In work published in Science Advances, a team of researchers have determined a new pressure scale, which is critical for understanding the Earth’s composition. Using x-rays from a uniquely powerful ...
