If Mars ever hosted microorganisms in its bygone oceans, their fossils might still be preserved in minerals—and now, we have a new potential way to find them

Additionally, Mars has unique environmental conditions, which could affect biosignature preservation over geological periods. Further studies are needed." Nevertheless, Sellam is proud to have led "the first astrobiology study to involve Algeria," and ...

Searching for small fossils in big rocks requires specialized tools --tools that scientists could also use to look for evidence of life on Mars in rocks that may be similar on both planets.

The question of whether life once existed on Mars may be answered by a new laser instrument from the University of Bern. The device can be carried by a rover to zap samples of the Red Planet to see if they contain traces of microfossils.

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

The first life on Earth formed four billion years ago, as microbes living in pools and seas: what if the same thing happened on Mars? If it did, how would we prove it? Scientists hoping to identify fossil evidence of ancient Martian microbial life have now found a way to test their hypothesis,

What tests can be performed on Earth to help us find signs of ancient life on Mars? This is what a recent study published in Frontiers in Astronomy and Spa | Space
