NASA Europa Mission to search for Aliens

NASA is planning a mission to Jupiter's moon Europa to search for signs of alien life on the icy, ocean-harbouring world. NASA has asked scientists to consider ways that a Europa mission could search for evidence of alien life in the plumes of water vapour that apparently blast into space from Europa's south polar region. These plumes, which NASA's Hubble Space Telescope spotted in December 2012, provide a possible way to sample Europa's ocean of liquid water, which is buried beneath the moon's icy shell, researchers said.
