Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external ...

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

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 that sits some 3,000 miles (4,828 kilometers) below the surface.However, ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

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 ...

Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges Sara Hashemi Daily Correspondent Deep at the ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

A recent study revealed that Earth’s inner core is slowing down, prompting scientists to investigate further. Their research led to an unexpected discovery: that inner core is not entirely solid.

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

Earth’s inner core is less solid than previously thought, reveals new research. American scientists have detected structural changes near the planet’s center. Changes to the inner core have ...
