Scientists have found that there is an extra innermost core at the center of the Earth made entirely of iron, measuring 400 miles in diameter.

Instead, it created distinct layers, marking the beginning of Earth's geological evolution. This discovery highlights the profound impact of the Moon-forming collision on Earth's structure and ...

The rotation of Earth’s inner core may have paused and it could even go into reverse, new research suggests.. The Earth is formed of the crust, the mantle and the inner and outer cores. The ...

The planet's internal structure comprises four layers: a rocky crust on the outside, then a rocky mantle, an outer core made of magma and a solid inner core. This metallic inner core, about 1,500 ...

When Earth first took shape more than 4.5 billion years ago, it set aside its most valuable riches for its heart. As the planet melted and separated into layers, dense metals like gold, platinum ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance. The ...

Of all Earth’s layers, the inner core is the most remote and mysterious. This solid sphere of iron and nickel is about 70% the size of the moon, with a radius of approximately 759 miles (1,221 ...

A new region of Earth's core could help scientists understand our magnetic field—the shield that protects life on the surface.

Behind the expedition to the Earth's mantle 04:06. Earth's inner core, a hot iron ball the size of Pluto, has stopped spinning in the same direction as the rest of the planet and might even be ...

A surprising discovery by Dutch scientists could offer new clues about how life began on Earth. Researchers from the ...

Of all Earth's layers, the inner core is the most remote and mysterious. This solid sphere of iron and nickel is about 70% the size of the moon, with a radius of approximately 759 miles.

(CNN) — Scientists who just months ago confirmed that Earth’s inner core recently reversed its spin have a new revelation about our planet’s deepest secrets — they identified changes to the inner core ...
