Nasa has obtained the clearest evidence yet that water flows on Mars, raising the possibility that the planet could be home to primitive life.
Dr Seth Shostak is the Senior Astronomer and Director from California's SETI Institute (Search for ExtraTerrestrial Intelligence Institute) which is dedicated to scanning the cosmos listening for any signs of intelligent life in space.
