Titan through different Cassini filters

Titan through different Cassini filters
Titan through different Cassini filters In most visible and near-infrared wavelengths of light, Titan appears nearly featureless, its smoggy atmosphere smoothly reflecting light like a billiard ball. The top three images show Titan as seen through medium-band red, green, and blue filters, the filters typically used to create color photos. In the bottom row, two images were taken through filters in which atmospheric methane is slightly (left) and strongly (center) absorbing, 620 and 890 nanometers, respectively. The rightmost image is taken at a near-infrared wavelength of 940 nanometers, where the atmosphere is somewhat transparent, so surface features are vaguely visible. Cassini took these images with its narrow-angle camera on 10 September 2016. NASA / JPL-Caltech / SSI
