Lakes on Titan
The strongest evidence yet for large lakes on Saturn’s moon Titan are in these RADAR images of the north polar regions of the large moon. At the very cold temperatures of Titan, these lakes are liquid methane or ethane. Water is hard as a rock at Saturn. These lake-like features may be lake beds, or marshy areas. They are certainly smooth, but may not currently be liquid. If they are, it would make Titan the only object other than Earth to have liquids on the surface at the present time.
