New fossil evidence from Mars suggests that the planet had wet and dry seasons billions of years ago - which would have provided ideal conditions for life.

For the study, researchers from The French National Centre for Scientific Research (CNRS), Paul Sabatier University, and Claude Bernard University Lyon 1 in France, looked at data from Nasa鈥檚 Curiosity rover, launched in 2012.

But what does the evidence actually show? Newshour's Owen Bennett-Jones has been speaking to William Rapin, a research scientist on this project.
