Imágenes del titán Moon de Saturno, capturado por el instrumento NIRCAM del telescampo espacial James Webb el 4 de noviembre de 2022. Izquierda: Imagen usando F212N, un filtro de 2.12 micrones sensible a la atmósfera inferior de Titán. Los puntos brillantes son nubes prominentes en el hemisferio norte. Derecha: imagen compuesta de color usando una combinación de filtros de nircam: azul = F140m (1.40 micras), verde = F150W (1.50 micras), rojo = F200W (1.99 micras), brillo = F210m (2.09 micras). Se etiquetan varias características de superficie prominentes: se cree que Kraken Mare es un mar de metano; Belet está compuesto por dunas de arena de color oscuro; Adiri es una característica de albedo brillante.

| 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. |
