Esta imagen de Galaxy NGC 4151, capturada por la cámara de campo ancho 3 del telescopio espacial Hubble, muestra flechas de brújulas y etiquetas 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 6,100 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 440,000 años luz de ancho.
Esta imagen muestra longitudes de onda visibles y ultravioletas que se han traducido en colores de luz visible. La tecla de color muestra qué filtros se usaron al recolectar la luz. El color de cada nombre de filtro es el color de luz visible utilizado para representar la luz infrarroja que pasa a través de ese filtro.

| About The Data | |
| Data Description | The HST observations include those from programs (B. Peterson) |
| Instrument | WFC3/UVIS |
| Exposure Dates | 07 Dec 2015 - 18 Feb 2016 |
| Filters | F350LP, F555W, F814W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the WFC3 instruments on the Hubble Space Telescope. Several filters were used to sample narrow 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: Luminosity: F350LP Cyan: F555W Orange: F814W |
| 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. |
