NASA's Perseverance rover finds potential signs of ancient life on Mars
NASA's Perseverance rover has found potential signs of ancient life on Mars. The rover obtained a sample of rock formed billions of years ago from sediment, and the rocks contain minerals that typically form as a result of a chemical reaction between mud and organic matter. This suggests the possibility that Mars once hosted microbial life, as similar reactions on Earth are often driven by the activity of microbes. However, the researchers caution that this is just a potential biosignature and not actual proof of ancient life. The area where the samples were found was likely once a river valley that led to a lake, more than 3.5 billion years ago. The samples were collected in 2021, and further research is needed to determine whether the features were generated by biological processes.
