Giant plumes of water have been spotted for the second time in the same location on Jupiter's moon Europa.
Jupiter's Europa is believed to have an underground ocean that could suggest it could support alien or extraterrestrial life.
Alien life signs in the solar system could be a lot more difficult than what researchers had imagined due to the damaging effects brought about by radiation.
Congress is reportedly enthusiastic about planetary science and wants to develop a two phase mission to Europa.
A recent study by scientists suggests that Europa could sustain life due to its similarity with the chemistry of our planet.
