The heart of our planet has been spinning unusually slowly for the past 14 years, new research confirms. And if this mysterious trend continues, it could potentially lengthen Earth's days — though the ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth's crust through its core. The very center of the planet, a solid ball of iron and nickel ...

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 inner ...

(CNN) — Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

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.

Forbes contributors publish independent expert analyses and insights. Eric Mack is a reporter covering science, sustainability and space. Science is hard. Writing about science can be hard too, ...

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 ...

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 be solid ...
