Earth's core might be layered like an onion, according to a new study that looked at the anomalous nature of waved in the ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

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 ...

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

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 ...

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

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 Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been assumed, ...

“It’s probably benign, but we don’t want to have things we don’t understand deep in the Earth.” Now, a recent study published in the scientific journal Nature Geoscience reveals a curious new detail ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface ...
