Jezero Crater on Mars was once home to a lake, delta and rivers. See an animation of what it could have looked like when ...

Thin, seasonal ice may have protected ancient lakes on Mars, allowing liquid water to last for decades despite cold ...

Small lakes on ancient Mars may have remained liquid for decades, even with average air temperatures well below freezing.

New climate modeling suggests that small lakes on ancient Mars could have stayed liquid for decades, even in a generally cold environment. Small lakes on early Mars may have stayed in liquid form for ...

How did Mars maintain surface liquid water billions of years ago? This is what a recent study published in AGU Advances hopes ...

This unusual crater on Mars resembles a butterfly, but its shape tells a story of a shallow impact, melted ice, and ancient ...

What can craters on Mars teach scientists about the Red Planet’s climate history? This is what a recent study published in Geology hopes to address as a team of researchers investigated ice buildup ...

Changes in Mars’ axial tilt (obliquity) drive shifts between polar ice caps at low obliquity and widespread mid-latitude glaciation at high obliquity. These cycles result in ice accumulating inside ...

Dark “slope streaks,” likely resulting from dust avalanches, stretch across an area of Mars called Acheron Fossae in this image from the High-Resolution Imaging Science Experiment (HiRISE) camera ...

NASA's Curiosity rover has sent back a striking new "postcard" from high on the slopes of Mount Sharp, offering a dramatic ...
