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

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 ...

Over a thousand miles from the surface, in Earth’s D” layer—right on the edge of the liquid metal outer core—there is a weird ...

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.

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.

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

While it's unlikely the deep-buried treasure chest will ever be cracked open, scientists call the discovery significant.

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 ...
