Nebulosa del anillo sur (imagen nircam)

Nebulosa del anillo sur (imagen nircam)

La estrella brillante en el centro de NGC 3132, aunque prominente cuando lo ve el telescopio Webb de la NASA con luz de infrarrojo casi, juega un papel de apoyo en la esculpir la nebulosa circundante. Una segunda estrella, apenas visible en la parte inferior izquierda a lo largo de uno de los picos de difracción de la estrella brillante, es la fuente de la nebulosa. Ha expulsado al menos ocho capas de gas y polvo durante miles de años.

Pero la estrella central brillante visible aquí ha ayudado a "revolver" la olla, cambiando la forma de los anillos altamente intrincados de esta nebulosa planetaria creando turbulencia. El par de estrellas está encerrada en una órbita apretada, lo que lleva a la estrella del atenuador a rociar material expulsado en una gama de direcciones mientras se orbitan entre sí, lo que resulta en estos anillos irregulares.

cientos de líneas rectas y iluminadas que perforan los anillos de gas y polvo. Estos "focos" emanan de la estrella brillante y corren a través de agujeros en la nebulosa como la luz del sol a través de los huecos en una nube.

Pero no toda la luz de las estrellas puede escapar. La densidad de la región central, establecida en verde azulado, se refleja en cuán transparente u opaco es. Areas that are a deeper teal indicate that the gas and dust are denser – and light is unable to break free.

Data from Webb’s Near-Infrared Camera (Nircam) se usaron para hacer esta imagen extremadamente detallada. Es repleto de información científica, y la investigación comenzará a seguir su lanzamiento.

Esta no es solo una imagen nítida de una nebulosa planetaria, también nos muestra objetos en las grandes distancias de espacio detrás de él. Las secciones rojas transparentes de la nebulosa planetaria, y todas las áreas fuera de ella, están llenas de galaxias distantes.

Busque la línea angulada brillante en la esquina superior izquierda. No es la luz de la estrella, es una galaxia lejana vista. Las espirales distantes, de muchas formas y colores, también salpican la escena. Aquellos que están más lejos, o muy polvorientos, son pequeños y rojos.

nircam fue construido por un equipo de la Universidad de Arizona y el centro de tecnología avanzado de Lockheed Martin.

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.
Instrument NIRCam
Exposure Dates 3 June 2022
Filters NIRCam> F090W, F187N, F212N, F356W, F405N, F470N
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  
Compass Image Colorful image of near-infrared light from a glowing cloud with a distorted ring-like shape, illuminated from within by a bright central star. The Southern Ring Nebula is a large, semi-transparent oval that is slightly angled from top left to bottom right. A bright white star appears at the center of this image. A large transparent teal oval surrounds the central star. Several red shells surround the teal oval, extending almost to the edges of the image. The shells become a deeper red with distance from the center. The bright central star has eight diffraction spikes. Behind the gaseous teal layers are deeper orange layers that are arranged like threads in a complex weaving. The red layers, which are wavy overall, look like they have very thin straight lines piercing through them, which are holes where light from a central star is traveling. The background of the image is black and speckled with tiny bright stars and distant galaxies.
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.
