Imagen anotada del sistema estelar beta pictoris capturada por Miri de Webb (instrumento de infrarrojo medio), con flechas de brújulas, una barra de escala y una tecla de color para referencia.
Las flechas de brújulas 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 en arriba).
La barra de escala está etiquetada en unidades astronómicas y arcos. Una AU es la distancia promedio de la tierra. (En nuestro sistema solar, Neptuno Orbits 30 Au del Sol). Arcseconds es una medida de distancia angular en el cielo. Un arco es igual a 1/3600 de un grado de arco. (La luna llena tiene un diámetro angular de aproximadamente 0.5 grados). El tamaño real de un objeto que cubre un arco en el cielo depende de su distancia del telescopio.
Esta imagen muestra longitudes de onda de luz intermedia invisibles que se han transferido a colores de luz visible. La tecla de color muestra qué filtros MIRI se usaron al recolectar la luz. The color of each filter name is the visible light color used to represent the infrared light that passes through that filter.

| About The Data | |
| Data Description | This image was created with Hubble data from proposal: (C. Stark). Image Processing: Alyssa Pagan (STScI). |
| Instrument | MIRI |
| Exposure Dates | 13 December 2022 |
| Filters | F1550C, F2300C |
| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI instrument. Several filters were used to sample specfic 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: F1550C Orange: F2300C |
| 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 | |
