What it means
It is the only world besides Earth with standing liquid on its surface, and the only moon with a thick atmosphere, denser at the ground than our own. At around one hundred and eighty degrees below zero Celsius, methane and ethane play the part water plays here: they evaporate, form clouds, fall as rain, carve channels and pool into lakes and seas. Water on Titan is a rock, and the bedrock is ice.
The claim comes from NASA.
