Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

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 ...

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

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 may be layered like an onion, with silicon and carbon creating distinct zones that explain seismic wave ...

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

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 ...

With findings on Earth’s polar extremes and its innermost core, scientists shaped how we look at the planet in 2025 in surprising and fascinating ways.

LOS ANGELES — 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 ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...
