NASA's Perseverance rover finds potential signs of ancient life on Mars
NASA just announced that its Perseverance rover recently found some promising signs of ancient life on Mars. The rover obtained a sample of rock formed billions of years ago from sediment and there are biomarkers indicating the potential presence of microbes once upon a time. Basically, the rocks contain minerals that typically form as a result of a chemical reaction between mud and organic matter. That doesn't necessarily mean that Mars once had life, as the minerals can form due to nonbiologi
