  • New research reveals ancient ripples on Mars, providing compelling evidence of long-lost lakes that once existed 3.7 billion years ago.

The article from Earth.com discusses the discovery of wave-like ripples on Mars' surface, which suggest that liquid water once flowed on the planet approximately 4 billion years ago. These ripples, identified in the Hellas Planitia region, were likely formed by water flowing over a sandy bed, similar to how ripples form in rivers or streams on Earth. This finding supports the theory that Mars had a wetter past, potentially capable of supporting life. The ripples were observed using high-resolution images from NASA's Mars Reconnaissance Orbiter, providing evidence of ancient water flows and contributing to our understanding of Mars' climatic and geological history.
