NASA's Perseverance rover discovered complex organic matter in rocks within the Jezero crater on Mars, potentially indicating ancient microbial life. The rocks contained macromolecular carbon, a type of organic matter commonly found in Earth rocks containing fossilized biological carbon and meteorites, detected by Perseverance's scientific instruments. While the discovery is significant, the formation mechanism of the macromolecular carbon remains unknown, and further analysis is needed to determine if it originated from biotic or abiotic processes. See more After more than five years of roaming the desolate and dusty landscapes of the Martian surface, NASA's Perseverance rover has come across some of the most intriguing evidence yet of ancient microbial life on the Red Planet. As detailed in a new paper published in the journal Science Advances , scientists confirmed that Perseverance had discovered a rock that contained "complex organic matter" — the building blocks of life, in biological parlance — in two rocks in a formation dubbed Bright Angel.
