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 ...

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 ...

The strongest hints yet that Mars once hosted living microbes are no longer theoretical models or ambiguous chemistry. They ...

Scientists exploring Mars have uncovered strong new evidence that the Red Planet once had wave-washed beaches and long-lasting water activity, making it an even more promising place to search for ...

The European Space Agency’s Mars Express orbiter captured this view of Mars’ south polar ice cap Feb. 25, 2015. Three years later, the spacecraft detected a signal from the area to the right of the ...

New findings from NASA's Perseverance rover have revealed evidence of wave-formed beaches and rocks altered by subsurface water in a Martian crater that once held a vast lake—considerably expanding ...

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 - and Imperial scientists provided crucial context. Led by NASA and featuring key analysis from Imperial College ...

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

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 ...

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 ...
