Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat ...

Deep beneath the surface of our planet lies the Earth’s core, a solid ball of iron under crushing pressure. Now, however, scientists conducting laboratory experiments have found evidence suggesting it ...

A bullet-speed experiment reveals that the Earth's inner core may be softer and more dynamic than previously thought.

Earth's core is rich with gold, and it's leaking out through the mantle and into the crust, new research has found. A new study of isotopes found in the volcanic rock that oozed out from deep under ...

PCWorld reports that scientists discovered Earth’s inner core has slowed its rotation relative to the crust, even appearing to stop moving in a phenomenon that occurs every 35 years. This iron-nickel ...

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 ...

For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps drive both the ...
