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

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

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

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

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 ...

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

A major scientific breakthrough has settled a decades-old debate about the moon’s interior. Researchers have confirmed that ...

The planet’s inner core was previously thought of as a hard, solid sphere. But a new study has found that its edges are softer than realized and actually changing shape as they press against the ...

But a new study has found that its edges are softer than realized and actually changing shape as they press against the liquid iron and nickel in Earth’s outer core. “The molten outer core is ...
