What is happening in Earth's inner core? Discover the implications of its deformation for seismic activity and navigation.

Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external ...

Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the ...

The inner core of the Earth, which is found about 3,000 miles (4,828 kilometers) under the surface, sits within a molten outer core, and is anchored by gravity. Once commonly thought of as a solid ...

Earth’s inner core is changing shape, scientists have found. The discovery resolves a long-simmering controversy about what’s happening at the heart of the planet — which was long thought to ...

Now, scientists believe that Earth’s inner core might be less solid than we previously thought. The findings are detailed in a study published February 10 in the journal Nature Geoscience and ...

Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges Sara Hashemi Daily Correspondent Deep at the ...

For decades, scientists have tried to understand how Earth’s inner core operates compared with the rest of the planet. Now, a team of researchers has found compelling evidence that it’s ...

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 inner core was widely thought of as a solid sphere.
