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 discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

Earth's innermost layer is called the core. The outside of Earth's core is made from molten nickel and iron that can reach temperatures of 9,000 degrees Fahrenheit (5,000 degrees Celsius).

New research sheds light on the Earth's "innermost inner core," offering new insight into the formation of the planet and its magnetic field. From our morning news briefing to a weekly Good News ...

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...
