Esta imagen del Galaxy NGC 1433 cercano, capturada por el instrumento de infrarrojo medio de Webb (MIRI) muestra flechas de brújula, barra de escala y clave 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).
En la parte inferior derecha hay una barra de escala etiquetada con 7,000 años luz, 30 arcos. La longitud de la barra de escala es aproximadamente un quinto el ancho total de la imagen. Debajo de la imagen hay una tecla de color que muestra qué filtros MIRI se usaron para crear la imagen y qué color de luz visible se asigna a cada filtro. De izquierda a derecha, los filtros Miri son: F770W es azul; F1000W y F1130W son verdes; y F2100W es rojo.

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI instrument. Several filters were used to sample wide 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: Blue: F770W, Green: F1000W+F1130W, Red: F2100W |
| 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. |
