NASA suggests that the best spot to look for alien life is Europa, one of Jupiter's moons.
New modelling shows the interior ocean of Jupiter's moon Europa should be able to support life.
Europa has a subsurface ocean and waters may not be as acidic as previously thought.
Europa has a thin atmosphere composed mostly of molecular oxygen and some water vapour.
Europa is the smallest of the four Galilean moons orbiting Jupiter, and the sixth-closest to the planet of all the 79 known moons of Jupiter.
