Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate ...

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

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 layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...

With findings on Earth’s polar extremes and its innermost core, scientists shaped how we look at the planet in 2025 in ...

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 ...

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 ...

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth’s inner core, according to seismologists from The Australian National University (ANU). By ...

Cartoon of the Earth with cutaway showing the mantle and inner and outer core. Magnetic field lines produced by the geodynamo extend into space and interact with the solar wind. The iron-rich core at ...
