The Earth’s core is 6,970 kilometers (4,330 miles) across and it is divided into an inner solid core and a liquid outer core. The liquid core is responsible for the magnetic field of our planet ...

There's a lot more to Earth than meets the eye. Far from being just a roundish rock barreling through space, our planet is composed of several layers held together by intense forces of gravity.

The planet, dubbed WASP-189b, isn't a new discovery. Scientists already knew that the world, which lies about 322 light-years from Earth, is a gas giant that orbits its star 20 times closer than ...

What this new research reveals is that the atmosphere of WASP-189b may have distinct layers—just like Earth. While Earth’s atmosphere contains layers—such as the stratosphere, whose ozone ...

Researchers are still discovering more about the Earth's center. A team at Australian National University (ANU) has found evidence of a new layer to the planet sitting within the inner core.

Newly discovered layers of ice buried a mile beneath Mars' north pole are the remnants of ancient polar ice sheets and could be one of the largest water reservoirs on the planet, according to ...
