Earthquake data suggest that all or small patches of the inner core's surface may be swelling and contracting.

Geophysicists studying seismic waves from earthquakes have found evidence suggesting that Earth's inner core not only rotates ...

The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it ...

This appears to be the case, to a rather stunning extent, in the instance of the reporting this week around new findings that researchers say shows the rotation of Earth’s inner core is slowing ...

As much as we have explored and modeled our planet, there are a number of mysteries that surround the Earth's inner core. This isn't that surprising, as it's pretty difficult to study a region ...

Earth’s inner core, a solid metal ball gyrating within the molten outer core, may be both slowing down and changing shape. Recent analyses of earthquake waves have suggested that around 15 years ago, ...

Although this inner core is white hot, the pressure is so high the iron cannot melt. The iron isn't pure—scientists believe it contains sulfur and nickel, plus smaller amounts of other elements.

Earth’s inner core has been slowing down for 14 years. It comes just weeks after another team of researchers suggested that the slight increase in the length of a day may be because Earth’s ...

How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain ...

New simulation methods reveal insights into the Earth's core and promise advances in neuromorphic computing for artificial ...

Well, the verdict is in. The Moon is not made of green cheese after all.
