On Earth, scientists study rock layers and the fossils embedded in them to learn about ancient life. A new study focused on red Mars - the desert planet - did something similar. It looked at the record of changing habitability preserved in ancient dune fields.

New research suggests that the Mars underground has the right ingredients for present-day microbial life.
