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.

| About The Object | |
|---|---|
| Object Name | Titan |
| Object Description | Saturn's moon |
| About The Data | |
| Data Description | This image was created with Webb data from proposal (C. Nixon) |
| Instrument | NIRCam |
| Exposure Dates | 4 Nov 2022 |
| Filters | Right: F212N Left: F140M, F150W, F200W, F210M |
| About The Image | |
| Color Info | 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 |
| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
