Nasa plans to hunt for alien life on Jupiter's icy moon

Jupiter's moon, Europa, has been described as one of the most likely places in the solar system for life to thrive. The moon, which lies 500 million miles from the sun, has an ocean lying beneath its surface that could host microbes. Now, Nasa says it has taken a small step to sending a robotic landing craft and underwater robots to Europa to search for life. An artists drawing illustrates the design for the Europa robot. A full exploration of Europa and its ocean will find out whether future robotic exploration will be possible.
