En esta imagen por la cámara de infrarrojo cercano de Webb (NIRCAM), un puñado de cientos de galaxias de fondo, que varían en tamaño y forma, aparecen junto con el sistema Neptuno.
neptuno, en comparación con la Tierra, es un planeta grande. Si la Tierra fuera del tamaño de un níquel, Neptuno sería tan grande como un baloncesto. En la mayoría de los retratos, los planetas exteriores de nuestro sistema solar reflejan este tamaño de otro mundo. Sin embargo, Neptuno parece relativamente pequeño en una vista de campo amplio del vasto universo.
hacia la parte inferior izquierda de esta imagen, se enfoca una galaxia espiral barrada. Los científicos dicen que esta galaxia en particular, previamente inexplorada en detalle, puede estar a unos mil millones de años luz de distancia. Las galaxias espirales como esta suelen estar dominadas por estrellas jóvenes que parecen azules en estas longitudes de onda.
nircam fue construido por un equipo en la Universidad de Arizona y el centro de tecnología avanzada de Lockheed Martin.

| About The Object | |
|---|---|
| Object Name | Neptune |
| Object Description | Gas giant |
| Distance | Neptune's average distance from Earth is 2.7 billion miles |
| About The Data | |
| Data Description | This image was created from JWST data from proposal: (K. Pontoppidan). |
| Instrument | NIRCam |
| Exposure Dates | 12 July 2022 |
| Filters | F140M, F210M, F300M, F460M |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample different infraraed 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: Red: F460M Orange: F300M Green: F210M Blue: F140M |

| 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 | |
