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 ...

These chemical oddities may explain why Earth seems to be deficient in certain elements — and could prove useful in catalysts ...

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 ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own ...

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

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...
