Caption:
Saturn is seen here in the background from the enigmatic moon Titan, which is the second largest moon in the solar system, with a diameter of about 5 150 km. It has a highly thick, orange atmosphere that covers the entire surface. There are many different kinds of carbohydrates in the atmosphere, but nitrogen is the dominant substance. Here you see a lake of ethane, and some freshly fallen ice on the surface. In actuality the atmosphere is so thick you would not be able to see Saturn this clearly.
