A NASA Mars rover has found more potential evidence of past life on the Red Planet. Scientists said this week that rocks analyzed by the Perseverance rover show signs of large complex carbon-containing molecules. On Earth, such molecules in rocks are linked to ancient microbial life. While the molecules can have non-biologic sources, scientists said that their presence alongside minerals formed in water-rich environments suggests conditions were at least hospitable for life there. Researchers added that better understanding of those molecules would require returning samples to Earth, but it's unclear if and when samples cached by Perseverance will be returned.
