Scientists have long wondered what lies at the very center of the Earth, and the latest research is putting weight behind a theory that our planet has a distinct ball of iron within its metallic core.

Around 3,000 kilometers (1,864 miles) beneath our feet, there's a mysterious band of material called the D" layer, which has long fascinated scientists for its lumpiness. Thin in patches and thick ...

When you look at photographs of Earth from space, the planet looks like a blue marble, with patterns of clouds lying on the surface of the marble. It seems as if Earth's atmosphere is incredibly thin, ...

thermal characteristics (temperature changes), chemical composition, movement, and density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical ...
