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

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

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

Searching for small fossils in big rocks requires specialized tools --tools that scientists could also use to look for ...

"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 ...

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 ...

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

Gypsum deposits formed on Mars could conceal evidence of past life on the planet — microbes similar to the first life that formed on Earth four billion years ago. But to test this hypothesis, we need ...

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