Titan (NIRCam)

Side-by-side images of Saturn’s moon Titan, captured by Webb’s Near-Infrared Camera on November 4, 2022, with clouds and other features labeled. Left image labeled “lower atmosphere and clouds” is various shades of red. Right image labeled “atmosphere and surface,” is shades of white, blue, and brown.

Images of Saturn’s moon Titan, captured by the James Webb Space Telescope’s NIRCam instrument Nov. 4, 2022. Left: Image using F212N, a 2.12-micron filter sensitive to Titan’s lower atmosphere. The bright spots are prominent clouds in the northern hemisphere. Right: Color composite image using a combination of NIRCam filters: Blue=F140M (1.40 microns), Green=F150W (1.50 microns), Red=F200W (1.99 microns), Brightness=F210M (2.09 microns). Several prominent surface features are labeled: Kraken Mare is thought to be a methane sea; Belet is composed of dark-colored sand dunes; Adiri is a bright albedo feature.

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

Both images were aquired by the James Webb Space Telescope using the NIRCam instrument.  The image on the left was made using a single filter: F212N. The image on the right is a composite of separate exposures with different filters used to sample different infrared wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. Blue=F140M, Green=F150W, Red=F200W, Luminosity=F210M
