Before & After: Titan above and below the atmosphere
Before & After: Titan above and below the atmosphere Cassini captured these images on 31 December 2015. Seen in visible light, Titan's atmosphere makes an opaque orange haze. Seen at an infrared wavelength at which methane is transparent, fuzzy surface features come into view. The "H" on Titan is made by two dark, dune-filled regions named Fensal and Aztlan.
