Esta imagen zoom de Urano, capturada por la cámara de infrarrojo cercano de Webb (NIRCAM) el 6 de febrero de 2023, revela impresionantes vistas de los anillos del planeta. El planeta muestra un tono azul en esta imagen de color representativo, realizado mediante la combinación de datos de dos filtros (F140m, F300m) a 1.4 y 3.0 micras, que se muestran aquí como azul y naranja, respectivamente.
En el lado derecho del planeta hay un área de brillo en el polo frente al sol, conocido como un capital polar. Esta tapa polar es exclusiva de Urano porque es el único planeta en el sistema solar inclinado de lado, lo que causa sus temporadas extremas. Un nuevo aspecto de la tapa polar revelada por Webb es un brillo sutil cerca del Polo Norte Uraniano.
En el borde de la tapa polar se encuentra una nube brillante, así como unas pocas características extendidas más débiles, justo hacia el norte del borde de la tapa, y se ve una segunda nube muy brillante en la extremidad izquierda del planeta. Dichas nubes son típicas para Urano en longitudes de onda infrarroja, y probablemente están conectadas a la actividad de la tormenta.

| About The Object | |
|---|---|
| Object Name | Uranus |
| Object Description | Planet |
| Distance | On February 6, 2023 Uranus was 19.67 AU from Earth (1.83 billion miles) |
| About The Data | |
| Data Description | This image was created from JWST data from proposal: (K. Pontoppidan) |
| Instrument | NIRCam |
| Exposure Dates | February 6, 2023 |
| Filters | F140M, F300M |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Two filters were used to sample medium wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Cyan: F140M, Orange: F300M |

| 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. |
| About The Data | |
