Ancient Water Found on Mars, Hinting at Past Life Possibilities**

**
Scientists discovered wave ripples in Martian rocks that suggest the planet once had open bodies of water, not just ice. These ripples were formed when wind pushed water back and forth 3.7 billion years ago during a warmer period. Researchers estimate these waves originated from shallow lakes on Mars’ surface, which was liquid enough to support life. The findings imply Mars could have sustained microbial life earlier in its history due to the presence of liquid water. This discovery also offers insights into how long these ancient lakes existed and supports the idea of an atmosphere once dense enough for warmth. The Curiosity rover has provided crucial evidence of such features, contributing to our understanding of Mars’ paleoclimate and potential for early life.
