The inner core of Earth may have changed shape in the past 20 years, according to a group of scientists. The inner core is ...

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

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 ...

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 ...

Scientists infer features of this innermost geographic layer—like the fact that it’s divided ... repeating earthquakes that pass through Earth’s core, scientists can track changes in the ...

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 ...

Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the ...

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 ...

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 ...

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.

In fact, the core might go through a process ... ‘Annual-scale variability in both the rotation rate and near surface of Earth’s inner core’, published in the journal Nature Geoscience.
