New research suggests that the thick, mineral-rich layers of clay found on Mars could hold the key to understanding whether the Red Planet ever harbored life. These layers, thought to have formed ...

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 ...

Bright white rocks found by NASA’s Perseverance rover hint at ancient Martian rain lasting millions of years, raising new questions about how wet Mars once was and what those conditions might mean.

Small lakes on ancient Mars may have remained liquid for decades, even with average air temperatures well below freezing. Using a climate model adapted for Martian conditions, a team of researchers ...
