Earth

Scientists know that the liquid outer core of the Earth consists mostly of iron, but the other elements present remain unknown. New research shows that oxygen is not present in the outer core.

Earth's geological record holds clues about supervolcano eruptions that may have had profound effects on the evolution of life. However, there is no evidence that such a supereruption is imminent.

Measurements from NASA's Terra spacecraft have been used to improve the most complete digital topographic map of Earth.

A new study demonstrates how salty water and gases transfer from the atmosphere into the Earth's interior. The research provides new insight into the evolution of our planet. Studying the physical processes of Earth can help astrobiologists understand what makes a planet habitable.

New research shows that oceanic crust can make its way right down to the lower mantle (deeper than 660km) and then be transported back to the surface.

Now on its way to Jupiter, NASA's Juno spacecraft has taken time to capture images of Earth and the Moon.

Using measurements from space, scientists have confirmed that, although the surface of the Earth is constantly changing, the planet is not expanding.
