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 ...

Researchers are still discovering more about the Earth's center. A team at Australian National University (ANU) has found evidence of a new layer to the planet sitting within the inner core. This ...

Back in my day, there were only four layers of Earth: the crust, mantle, liquid outer core and solid inner core. Now, scientists have revealed a new, distinct layer within our planet’s inner core, ...
