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

A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation speed – it also appears to change in shape, with subtle variations appearing in the way ...

Earth's inner core may have changed shape, according to researchers studying unknown transformations deep within the planet.

Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the ...

The Earth’s inner core is 3,000 miles below the surface and was thought to be a solid sphere held by gravity in the molten ...

Researchers found evidence that the Earth's inner core is changing shape, suggesting unseen processes affecting its movement ...

The inner core is made from solid iron and nickel. In this diagram, the red lines represent the edges of the tectonic plates that make up the Earth's crust. For example, iron is mined from the ...

In contrast, the methods used by the researchers allowed them to measure the phase diagram of iron under conditions mimicking those at the depths of the Earth, which they could then use to extrapolate ...

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram ... the Earth (see image below right), the liquid metal that makes up the outer core ...
