The Earth's inner core is a solid sphere composed primarily of iron and nickel, located at the center of our planet. Understanding its dynamics and structure is crucial for comprehending the Earth ...

We are unsure of the nature of the strange doughnut-shaped structure discovered inside the Earth's core. We thought Earth had ...

The Earth has a shell-like structure. It is divided into a core (inner and outer core), a mantle (lower and upper mantle, separated by a transition zone), and the earth's crust. You are free to ...

Our history. Research shows there are little-known chapters in that history, deep within Earth's past. In fact, Earth's inner core appears to have another even more inner core within it.

Our planet's interior is much too deep and hot to explore with probes, so scientists rely on seismic waves to understand and model its structure. Seismic waves are shock waves tha ...

What we have always known about the Earth’s inner core has changed, and researchers have provided us with new information. Scientists recently uncovered a hidden structure in the Earth’s core, which ...

The Earth's inner core was once liquid ... These findings suggest that certain chemistry or structure that had previously not been considered might not require such an unreasonably large supercooling.

This appears to be the case, to a rather stunning extent, in the instance of the reporting this week around new findings that researchers say shows the rotation of Earth’s inner core is slowing ...

Earliest inner solar system planetesimals shaped the inventory of moderately volatile elements in terrestrial planets.
