Seismic imaging in northeastern China revealed both the top (X1) and bottom (X2) boundaries of a tectonic plate (blue) that formerly sat at bottom of…
This graph shows how the amount of water in the atmosphere of Mars varies depending on the season. During global and regional dust storms, which…
This artist’s concept depicts the early Martian environment (right) – believed to contain liquid water and a thicker atmosphere – versus the cold, dry environment…

Current understanding is that the chemical composition of the Earth’s mantle is relatively homogeneous. But experiments conducted by ETH researchers now show that this view…
The lightning phenomenon known as a sprite depicted at Jupiter in this illustration. Jupiter’s hydrogen-rich atmosphere would likely make them appear blue. In Earth’s upper…
The loss of huge ice masses can contribute to the warming that is causing this loss and further risks. A new study now quantifies this…
