Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

Researchers have found evidence of changes in the structure of the Earth's core. University of Southern California team, led by Professor John Vidale, was investigating the inner core's rotation – a ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

A groundbreaking study published in Nature Communications offers new insights into Earth’s inner core, potentially solving long-standing mysteries about seismic anomalies. An international team led by ...

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 Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, ...
