Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

The Earth's internal layers including the mantle, outer core, and inner core. Scientists believe that the inner core’s rotation began to slow down in 2010, but what that really means has been up for ...

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 ...

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

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are ...

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 ...

(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 ...

The wheel of time isn’t turning like it used to. Scientists have discovered that our planet’s core has been rotating at a slower rate for nearly 15 years — and it could mean longer days for some. 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 ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...
