A mudstone sample from Jezero Crater shows textures and minerals that on Earth often form through microbial activity. Scientists caution that nonbiological processes could also explain the features, ...

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 ...

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 ...

NASA’s interim administrator, Sean Duffy, was fired up on Wednesday when he joined a teleconference to talk about new scientific findings that concerned the potential for life to have once existed on ...

A rock sample collected by NASA’s Perseverance Mars rover may contain evidence of ancient microbial life, preserved for billions of years on the Red Planet. The potential “biosignature” is not direct ...
