Earth's core might be layered like an onion, according to a new study that looked at the anomalous nature of waved in the ...

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 ...

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

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

The Earth's internal layers including the mantle, outer core, and inner core. Scientists believe that the inner core’s rotation began to slow down in 2010, but what that really means has been up for ...

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

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 ...

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

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...

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 ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance. The surface ...
