The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

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 ...
