Not only is Earth's inner core spinning and growing, but it's also changing shape, according to new research. Our planet's ...

The outer core, composed of liquid iron and nickel, is known for its role in generating Earth's magnetic field. Until now, its impact on the inner core was poorly understood. The study reveals ...

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 ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

Earth's core is the beating heart of our planet as it produces a magnetic field that protects life from burning up in the Sun's radiation. The inner core spins independently from the liquid outer ...

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

Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the inner core was widely thought of as a solid sphere.

Well, the verdict is in. The Moon is not made of green cheese after all.

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our ...

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. Now, ...
