An international team of astrobiologists have claimed that organic molecules discovered by NASA’s Curiosity Mars rover could be evidence of life on Mars. The team claims that the presence of the compounds called “thiophenes,” which are usually found in coal, crude oil, etc back on Earth, could be an indication of ancient life on Mars. While thiophenes comprise two bio-essential elements, carbon and sulfur, there are chances they could’ve been formed during meteor impacts that heat sulfates to high temperatures. However, the team isn’t jumping over any conclusions just yet. If the compounds were indeed an indication of Martian life, they could’ve been the outcome of bacteria breaking down sulfates some three billion years ago.
