Organic molecules discovered by Curiosity Rover consistent with early life on Mars
Organic compounds called thiophenes were recently discovered on Mars, and a new study published in the journal Astrobiology thinks their presence would be consistent with the presence of early life on Mars. Phys.Org reports: "We identified several biological pathways for thiophenes that seem more likely than chemical ones, but we still need proof," Washington State University astrobiologist Dirk Schulze-Makuch said. "If you find thiophenes on Earth, then you would think they are biological, but on Mars, of course, the bar to prove that has to be quite a bit higher."
