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

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than ...

Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an ...

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

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 of ...

Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core. It's believed to play an important role in maintaining the planet’s ...

Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic ...

Notably, the Earth is made up of four main structures: the outer crust, a semi-liquid mantle, a molten outer core, and a dense inner core. Earth's core plays a vital role in sustaining life on our ...

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 that ...

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...
