Possible giant "karstic" caves that formed when slightly acidic water dissolved bedrock have been identified on Mars and hailed as one of the best locations on the Red Planet to search for preserved ...

A recent discovery on Mars has revealed something truly fascinating: massive water-carved caves that might just be hiding evidence of ancient life. These caves, which formed when slightly acidic water ...

Researchers say life on Mars may be hidden in caves. A new study suggests eight "skylights" may be entrances to underground spaces where evidence of ancient microbial organisms could be found.

The rover’s science instruments found that the formation’s sedimentary rocks are composed of clay and silt, which, on Earth, are excellent preservers of past microbial life. The findings were made ...

A long time ago, life left microscopic signatures on Mars — or did it? That's the question NASA scientists have worked for years to answer. On Wednesday, NASA researchers said the answer might be in a ...

NASA announced it found promising potential biosignatures on Mars. Potential biosignatures are things like chemicals and structures that could be a result of life on the planet, but more research was ...
