Significance: For the first time, apparent frost linked to rainfall has been observed on another body in the solar system. Frost appeared to form on Saturn's moon Titan in the wake of a storm. Hydrocarbon rain-darkened the surface in an area called Yalaing Terra. Later, data from Cassini's Visual and Infrared Mapping Spectrometer (VIMS), Imaging Science Subsystem (ISS) and RADAR were used in the analysis of surface brightening at four locations after cloud-bursts on Titan. The bright, frosty-looking area gradually faded over the course of about a year.
