Imagen de la nebulosa de cangrejo capturada por Nircam y Miri de Webb, con 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 desde arriba).
La barra de escala está etiquetada en años luz, que es la distancia que la luz viaja en un año terrestre. (La luz tarda 2 años en viajar a una distancia igual a la longitud de la barra). Un año luz es igual a aproximadamente 5.88 billones de millas o 9.46 billones de kilómetros. El campo de visión que se muestra en esta imagen es de aproximadamente 10 años luz de ancho.
Esta imagen muestra longitudes de onda de luz de infrarrojo cercano e infrarrojo intermedio que se han traducido en colores de luz visible. La tecla de color muestra qué filtros Nircam y Miri se usaron al recolectar la luz. El color de cada nombre del filtro es el color de la luz visible utilizado para representar la luz infrarroja que pasa a través de ese filtro.

| About The Data | |
| Data Description | This image was created with Webb data from proposal: 1714 (T. Temim) - Image Processing: Joseph DePasquale (STScI) |
| Instrument | NIRCam, MIRI |
| Exposure Dates | 31 Oct 2022, 24 Feb 2023, 17 Mar 2023 |
| Filters | NIRCam: F162M, F480M; MIRI: F560W, F1130W, F1800W, F2100W |
| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam and MIRI instruments. Several filters were used to sample specific 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: F162M, Light Blue: F480M, Cyan: F560W, Green: F1130W, Orange: F1800W, 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. |
| 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. |
