This creates pools that, turn, become vast lakes and, perhaps, seasonal oceans. has other sense, large shifting areas sand covering plains discovered. also seas, well, along oceans frozen lava. Do super-chilled concoctions ammonia, liquid nitrogen, water percolate surfaces Enceladus Triton? we can only guess possibilities. ‘Alien Seas’ serves up part history, current research, theory offers rich buffet “seas” worlds.
