Scientists have reported potential signs of ancient microscopic life on Mars, based on chemical activity detected by NASA's Perseverance rover. While the findings are exciting, further analysis is needed before drawing conclusions. The rover has gathered 30 samples from locations believed to have hosted life billions of years ago, but there is currently no evidence of present-day life. The retrieval of these samples to Earth has been delayed due to budget issues. Experts caution that non-biological processes could explain the findings. Teljes cikk (Euronews.com)
