Earth's composition is more complicated than we think and is changing continuously every day. The inner part of the planet can be divided into three different layers: crust, mantle, and core.

University of Southern California scientists have proven that the Earth's inner core is backtracking—slowing down—in relation to the planet's surface, as shown in new research published in Nature.

This appears to be the case, to a rather stunning extent, in the instance of the reporting this week around new findings that researchers say shows the rotation of Earth’s inner core is slowing ...

Currently, the rotation between the inner and outer cores is becoming less distinct. When researchers say “reverse,” they mean the inner core is rotating slightly slower than the outer core, Brown ...

A single rotation of our planet takes 24 hours ... which matches observations by astronomers and satellites. Earth’s inner core has been slowing down for 14 years. It comes just weeks after ...

Seismic waves travel through the Earth's inner core faster between the north and ... which are themselves anisotropic -- parallel with Earth's rotation axis.

Deep within Earth 's fiery belly, beneath layers of molten rock, a peculiar jig is underway. Our planet's inner core, a solid iron ball bigger than Pluto, isn't just spinning – it's doing a ...

solid ball at the center of our planet has been reducing its speed for years as part of an oscillating cycle Rudy Molinek A new study suggests more solar radiation reached Earth while the magnetic ...

Published in the journal Nature Geoscience on Monday, the peer-reviewed research suggests that the solid inner core of the Earth could experience changes in its rotation every several decades.

We have been adding “leap seconds” to time kept by our atomic clocks, but soon we may have to subtract one. Are the tiny adjustments worth the bother?

Mercury ' s inner core is solid and about the same ... Mercury takes 59 Earth days to complete one rotation on its axis and 88 Earth days to complete one revolution around the Sun.
