Meridiani Journal looks at the sub-surface water on Titan



Titan is already known to have lakes and seas of liquid methane, but now the evidence is growing that it also harbours a subsurface ocean of water, which may come to the surface periodically via cryovolcanoes (spewing ice or water instead of lava). As the two linked articles describe, studies of Titan’s variable spin rate have bolstered the case for an interior water / ammonia ocean, while new evidence for ice flows resulting from cryovolcanic eruptions have been found on the surface.
