The findings potentially solve the paradox of how liquid water seems to have persisted on Mars even when the climate grew too cold.

The discovery suggests that parts of Mars may once have supported tropical-like climates, complete with heavy, sustained rainfall.

A new study suggests a habitable past and signs of ancient microbial processes on Mars. Led by NASA and featuring key analysis from Imperial College London, the work has uncovered a range of minerals ...

A Martian mystery that sparked years of debate — an alleged lake buried beneath miles of ice — now looks far less watery than scientists hoped. A new radar study from NASA’s Mars Reconnaissance ...

NASA’s Perseverance rover has uncovered signs of an ancient Martian shoreline, hinting at long-lasting lakes, subsurface water activity, and conditions that may once have supported life on the Red ...

New findings from NASA's Perseverance rover have revealed evidence of wave-formed beaches and rocks altered by subsurface ...

Utah’s Great Salt Lake is a place of extremes, and its ecosystem is evidence that life can thrive under some of Earth’s most hostile conditions. Scientists say it may hold clues for life on other ...

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 ...

For seven years, a puzzling signal beneath the Martian south pole has divided planetary scientists over whether a hidden lake of liquid water could really exist in such brutal cold. Now NASA ...
