Esta imagen del sistema Fomalhaut, capturada por el instrumento de infrarrojo medio de Webb (MIRI), muestra flechas de brújulas, barra de escala y clave de color para referencia. Las etiquetas indican las diversas estructuras. A la derecha, se resalta una gran nube de polvo y los retiros lo muestran en dos longitudes de onda infrarrojas: 23 y 25.5 micras.
Las flechas de la brújula norte y este muestran la orientación de la imagen en el cielo. Tenga en cuenta que la relación entre el norte y el este en el cielo (como se ve desde abajo) se voltea en relación con las flechas de dirección en un mapa del suelo (como se ve desde arriba).
La barra de escala está etiquetada en unidades astronómicas, que es la distancia promedio entre la Tierra y el Sol, o 93 millones de millas. El anillo exterior tiene aproximadamente 240 unidades astronómicas de diámetro.
Esta imagen muestra longitudes de onda de luz de infrarrojo medio invisibles que se han traducido en colores de luz visible. La tecla de color y las etiquetas muestran qué filtros MIRI se usaron al recolectar la luz.

| 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 | |
| Data Description |
|
| Instrument | The science instrument used to produce the data. |
| Exposure Dates | The date(s) that the telescope made its observations and the total exposure time. |
| Filters | The camera filters that were used in the science observations. |
| About The Image | |
| Image Credit | The primary individuals and institutions responsible for the content. |
| Publication Date | The date and time the release content became public. |
| Color Info | A brief description of the methods used to convert telescope data into the color image being presented. |
