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.

The Earth's outer core may be more dynamic than we once thought. Dan Shim/ASU "For years, it has been believed that material exchange between Earth's core and mantle is small," Dan Shim, an Earth ...

The Earth’s inner core is separated from the rest of the planet by its liquid outer core, so it rotates at a different pace and direction.

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 ...

Water leaking into the Earth may be wrapping the core in crystals, a study has suggested. The study may help explain a weird area in the outer core that has long puzzled scientists.

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 ...

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.

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

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 ...
