A hot topic in science over the past few decades has been whether liquid water is present or has been present on Mars in the past few millions of years. But despite a lot of research no conclusive answer has been put forward to date. Our international team has now hunted down another piece of evidence. By comparing satellite images of Mars with mud flows on Earth, we found that running water must have existed on the red planet relatively “recently”, in the past million years.
