If Mars ever hosted microorganisms in its bygone oceans, their fossils might still be preserved in minerals—and now, we have ...

Additionally, Mars has unique environmental conditions, which could affect biosignature preservation over geological periods.

Planetary scientists in Algeria and Switzerland have developed a scientific instrument that could help hunt for signs of life ...

"What this study in Algeria really does is it highlights that you can use ... "And chemical methods are just a little more ...

"We proved that our instrument is capable of detecting signatures of life in gypsum," he added, suggesting it might help do ...

Scientists found fossil-like traces in gypsum, suggesting ancient microbial life may have existed on Mars billions of years ...

Scientists may finally have a way to detect ancient life on Mars by studying microbial fossils preserved in sulfate minerals.

Gypsum from Algeria stood in for Martian sulfate deposits However, in the distant past Mars was a very different place with a thicker atmosphere and so much liquid water that much of the surface ...

Researchers tested this technology in gypsum deposits in Algeria, a geological site analogous to those on Mars. The results are encouraging: LIMS identified microbial filaments and minerals associated ...

Scientists are using a laser-based tool to aid future Mars missions in identifying evidence of life on the Red Planet.
