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’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 ...

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.

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 ...

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

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 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 ...

In fact, the inner core's rotation completely changed direction in 2010 and has been slowly moving in the opposite direction since. The mantle is the largest of the Earth's layers and consists of ...

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 inner core was widely thought of as a solid sphere.

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.
