Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core. For decades, planetary scientists suspected that the solid inner core deformed over time as it spun.

Researchers had long suspected the Earth had another layer at its core, but because its composition is so similar to the layer surrounding it, the innermost inner core was hard to spot.

The surface of Earth's inner core may be shape-shifting ... in waves that just glanced the surface of the core, elucidating its outermost layer. Since the first studies of the inner core in ...

Inner core The inner core is 2900 km below the Earth’s surface, in the centre of the Earth, and is the hottest layer. It is spherical and solid and made up of iron and nickel. Its temperatures ...

Earth's inner core, the innermost geologic layer of our planet, which is a solid ball with a radius of about 1,220 km, is now rotating in the opposite direction than when it was discovered nearly ...

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

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.

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our understanding of its history and evolution within the Solar System.

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’s shape ...

This increased movement makes the inner core less rigid ... the intricacies of our planet and its dancing atoms, the Earth's evolving layers have yet to be pulled back fully.

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...
