Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

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 ...

Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface ...

Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

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

Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many years. For decades, scientists have known the inner core is solid thanks to ...
