Identifying the composition of the earth's core is key to understanding how our planet formed and the current behavior of its interior.

The composition of the Earth's core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well.

A team of scientists has proposed a novel model for the generation of a global magnetic field in the ancient moon, which could help solve a decades-old mystery about the presence of magnetized rocks on the moon’s surface.

The inner core of the Earth is simultaneously melting and freezing due to circulation of heat in the overlying rocky mantle, according to new research from the University of Leeds, UC San Diego and the Indian Institute of Technology.

New research gives the first accurate estimate of how much faster the Earth's core is rotating compared to the rest of the planet.
