A new study led by a team at Western University in Ontario, Canada finds that the subsurface ocean of Titan – the largest moon of Saturn – is most likely a non-habitable environment, meaning that any hope of finding life in this icy world is dead in the water. This is discouraging since Titan is the most organic-rich icy moon in the Solar System, so if its subsurface ocean turns out to be not habitable for life, it does not bode well for the habitability of other known icy worlds like Jupiter’s moons Europa and Ganymede and Saturn’s moon Enceladus. This finding, if proven correct, means it is far less likely that space scientists will ever find life in the outer Solar System planets Jupiter, Saturn, Uranus, and Neptune.
