NASA discovers unusual green spots on Mars hinting at past microbial life

NASA has discovered unusual "green spots" on Mars, suggesting the possibility of past microbial life. These spots were found on a section of Martian rock called Wallace Butte, raising interest in the planet's history and potential for life. The green markings, associated with microbial processes on Earth, were revealed by the Perseverance rover. While they may indicate past biological activity, NASA has stated there is no evidence of current life on Mars. This discovery adds to the understanding of Mars, which may have once had oceans. Ongoing research, including AI studies, aims to identify the best locations for searching for signs of life on the planet.
