Recent research suggests that the gullies found on Mars might have been formed by liquid water in the not-so-distant past. While the elevated locations of these gullies don’t align with our expectations of recently flowing water, a study by US scientists proposes that under specific conditions, liquid water could have caused the formation of these features as recently as 630,000 years ago. The study also indicates that flowing water erosion better explains the Martian landscape features compared to CO2-related erosion. The findings not only have implications for understanding Mars’ geological history but also offer new perspectives on the potential for past and present life on the red planet.
