ARP 107 (imagen de la brújula)
Subtítulo
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 (visto desde abajo) está invertida en relación con las flechas de dirección en un mapa del suelo (visto desde arriba).
La barra de escala está etiquetada en años luz, que es la distancia que viaja la luz en un año terrestre. (La luz tarda 75.000 años en recorrer una distancia igual a la longitud de la barra). Un año luz equivale aproximadamente a 5,88 billones de millas o 9,46 billones de kilómetros. El campo de visión que se muestra en esta imagen tiene aproximadamente 450.000 años luz de diámetro.
Esta imagen muestra longitudes de onda de luz invisibles en el infrarrojo cercano y el infrarrojo medio que se han traducido en colores de luz visible. La clave de color muestra qué filtros NIRCam y MIRI se utilizaron al recolectar la luz. El color del nombre de cada filtro es el color de luz visible utilizado para representar la luz infrarroja que pasa a través de ese filtro.

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam and MIRI instruments. 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: NIRCam> Blue: F090W + F150W, Green: F200W+ F277W, Red: F356W + F444W MIRI> Yellow: F770W, Orange: F1000W, Red: F1500W |
| 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 | |
| Color Info | A brief description of the methods used to convert telescope data into the color image being presented. |
| Compass and Scale Image | An astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made. |
