Esta imagen de la Nebulosa del Ring Southern (NGC 3132), capturada por la cámara de infrarrojo cercano de Webb (NIRCAM), muestra flechas de brújulas, 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 0.25 años en viajar a una distancia igual a la longitud de la barra de escala). 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 1.4 años luz de ancho.
Esta imagen muestra longitudes de onda de onda de infrarrojo cercano invisibles que se han traducido en colores de luz visible. La tecla de color muestra qué filtros Nircam 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 Webb data from proposal . It is part of Webb Early Release Observations. The Early Release Observations and associated materials were developed, executed, and compiled by the ERO production team: Jaclyn Barrientes, Claire Blome, Hannah Braun, Matthew Brown, Margaret Carruthers, Dan Coe, Joseph DePasquale, Nestor Espinoza, Macarena Garcia Marin, Karl Gordon, Alaina Henry, Leah Hustak, Andi James, Ann Jenkins, Anton Koekemoer, Stephanie LaMassa, David Law, Alexandra Lockwood, Amaya Moro-Martin, Susan Mullally, Alyssa Pagan, Dani Player, Klaus Pontoppidan, Charles Proffitt, Christine Pulliam, Leah Ramsay, Swara Ravindranath, Neill Reid, Massimo Robberto, Elena Sabbi, Leonardo Ubeda. The EROs were also made possible by the foundational efforts and support from the JWST instruments, STScI planning and scheduling, Data Management teams, and Office of Public Outreach. |

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample narrow and broad 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: Red: F470N, Red: F405N, Yellow: F356W, Green: F212N, Cyan: F187N, Blue: F090W |
| 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 | |
