A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation speed – it also ...

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet ...

Not only is Earth’s inner core spinning and growing, but it’s also changing shape, according to new research. Our planet’s [… ...

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 is changing.

First, a few basics. The Earth’s inner core, which is smaller than the moon, is solid iron and nickel. It’s surrounded by a layer of molten metal known as the outer core, followed by the Earth’s ...

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than ...

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 ...

Earth's inner core is undergoing structural transformation. 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 ...

A new study reveals that the Earth's inner core is undergoing a structural transformation. A new study by USC scientists, ...

Earth’s core is pretty dynamic. Its spin speeds up and slows down based on how its two primary layers are behaving. As we improve the waveform techniques used to study the deepest layer ...

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 ...
