Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...

Earth's inner core may have paused and reversed its spin, a new study suggests. Earthquakes and nuclear blasts can send seismic waves through the mysterious solid-iron core. Those waves hint that the ...

Earth’s core consists of a solid iron-nickel ball rotating within a layer of liquid metal. But that ball may not be as simple as it seems: new research suggests the inner core contains its own inner ...

Most of us learned in school that the Earth has four layers in its internal structure: the crust, the mantle, the outer core, and the inner core. But recent research reveals that the inner core itself ...

Deep earth may be slowing its roll. Earth’s solid iron inner core appears to be spinning at a slower rate than the planet, according to a new study — but no worries, scientists believe it’s been ...
