Earth’s inner core has both changed its relative rotation rate and deformed in the past few decades, according to an analysis of seismic waves recorded when the inner core occupied the same relative ...

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate than a simple metal ball. Instead of a single solid sphere, the inner core ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

Cross-sectional illustration of Earth's layers, down to molten core. Scientists in China recently made a discovery at the heart of our planet: Every 8.5 years, the Earth's inner core wobbles around ...

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 ...

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 ...

Earth's largest gold reserves are not kept inside Fort Knox, the United States Bullion Depository. In fact, they are hidden much deeper in the ground than one would expect. More than 99.999% of ...
