The inner core of our planet has started spinning slower and slower, new research has revealed Compared to the speed of the Earth's surface, the inner core was previously thought to rotate faster.

While InSight’s seismometer has been patiently waiting for the next big marsquake to illuminate its interior and define its crust-mantle-core structure, two scientists, Takashi Yoshizaki (Tohoku ...

To understand the mantle—the largest layer of Earth’s rocky body—scientists drill deep cores out of the Earth. Scientists drilled the deepest core yet and recovered serpentinized peridotite that forms ...

Earth's core has baffled researchers for decades, and it still contains many secrets. Recent studies show this hot furnace buried deep under our feet is weirder than we think. The inner core may be ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust last year, pulling out a treasury of geological goodness. The result ...

The rotation of Earth's inner core may have paused and it could even go into reverse, new research suggests. The Earth is formed of the crust, the mantle and the inner and outer cores. The solid inner ...
