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...
Diagram of Earth's structure showing inner core, outer core, mantle and crust. A doughnut-shaped structure almost 3,000 kilometers beneath our feet has been discovered by scientists...
Scientists have discovered that the inner core’s surface is changing shape, challenging previous assumptions about its solid nature. This dynamic activity could influence Earth’s rotation and …
A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation speed – it also appears to change in shape, with subtle variations appearing in the way acoustic …
A doughnut-shaped region thousands of kilometers beneath our feet within Earth's liquid core has been discovered, providing new clues about the dynamics of our planet's magnetic field.
On September 3, 2024, researchers at Australian National University said they found the donut-shaped feature by analyzing seismic waves passing through the core.
Deep beneath our feet lies a realm shrouded in mystery—the Earth’s inner core. Recent studies have unveiled surprising insights into this hidden world, suggesting that the inner core’s rotation is not as …
Scientists have proposed that Earth’s moon-sized inner core revolves independently of the mantle and crust, and that it is now backpedaling relative to those other layers. Something strange...
Using a new way of studying these waves, my colleague Xiaolong Ma and I have made a surprising discovery: there is a large donut-shaped region of the core around the Equator, a few hundred …
Hidden thousands of miles beneath the surface, the planet’s inner core is inaccessible to direct observation, leaving researchers to infer its behavior from seismic signals. These subtle shifts are …
