This is a false-colour composite image I made of Saturn's moon Titan, using raw images taken by Cassini spacecraft using broadband infrared and narrowband methane filters. This allows us to see through Titan's thick atmosphere, making visible the clouds of methane and dark fields of sand along the equatorial region.
Sand on Titan is not made of silicates as on Earth, but of solid hydrocarbons that precipitate out of the atmosphere. These then aggregate into millimetre-sized grains by a still unknown process.

Looking forward to the dragonfly mission, and the view its going to get of the deep dune seas, deepest and most extensive dunes we know of in the solar system. Kinda like a cold arrakis.
What would be the AQI there???
