A newly discovered doughnut shape in Earth's outer core may reveal elements that help drive the formation of the planet's magnetic field.

Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core. It's believed to play an important role in maintaining the planet’s ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

The magnetic field and the liquid outer core are further stabilized by the more solid inner section. The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth.

A new study from USC scientists reveals the Earth’s inner core is undergoing structural transformation. (USC Graphic/Edward Sotelo/TNS) LOS ANGELES — USC scientists have made a groundbreaking ...

USC scientists have made a groundbreaking discovery about the nature of Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.

Earth's rotation is speeding up, leading to shorter days and potential timekeeping adjustments. Scientists predict that by ...

The 2003 disaster film "The Core" imagines that the rotation of Earth's center has stalled, damaging the magnetic field that envelops the planet — and triggering a violent lightning storm that ...
