Mating of LVA
Saturn's clouds are full of raw beauty, but they also represent a playground for a branch of physics called fluid dynamics, which seeks to understand the motion of gases and liquids.
This composite image, composed of two images taken with Cassini's visual and infrared mapping spectrometer, shows a crescent view of Saturn's moon Titan. The data were obtained during a flyby on J...
