Strange grooves, swirling valleys, and hidden ice far from Mars’s poles reveal a surprisingly recent ice age, as new ESA images expose how the Red Planet’s climate once dramatically shifted.

Captured by the European Space Agency’s (ESA) high-resolution stereo camera, Mars Express, the image close up of the planet’s south polar ice cap extends across its cratered highlands to the Hellas ...

Until recently, Mars was studied only through telescopes and some data that was recorded from early spacecraft. It was thought that Mars' polar regions were the only significant reservoirs of ice, ...

It was one of the most provocative findings of the past decade in planetary science: a potential underground lake of liquid water beneath Mars’ South Pole. First reported in 2018 by a team using the ...

This image, combining data from two instruments aboard NASA's Mars Global Surveyor, depicts an orbital view of the north polar region of Mars. The ice-rich polar cap (the quasi-circular white area at ...

Are researchers searching in the wrong locations on Mars to find ancient life? This is what a recent study published in Astrobiology hopes to address as a team of researchers investigated searching in ...

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 ...

A new climate model suggests that ancient lakes on Mars may have survived for decades beneath thin layers of ice that formed and melted with the seasons. The findings help resolve a long-standing ...
