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

What is the Earth's core? Earth's diameter is about 7,900 miles. The planet's internal structure comprises four layers: a rocky crust on the outside, then a rocky mantle, an outer core made of ...

An analysis of Hawaii’s volcanic rocks revealed Earth’s core is leaking gold and other precious metals, a study found. The elements emerge when ocean islands form.

“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 human timescale,” Vidale said in a press statement.

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.
