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

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.

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.

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 Earth is leaking. The good news is this isn’t bad news, because the Earth is leaking gold and other precious metals.

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 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 ...

The Inner Layers of the Earth Might Not Match Up “The molten outer core is widely known to be turbulent, but its turbulence had not been observed to disrupt its neighbor the inner core on a ...

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 ...

It is true that the outer core generates electrical currents that sustain the planet’s magnetic field, but Vidale says shifts in the Texas-size inner core are too minuscule to have an impact.
