Nebula del anillo sur (imagen de Miri)
El telescopio Webb de

de la NASA ha revelado la capa de polvo alrededor de la segunda estrella, que se muestra a la izquierda en rojo, en el centro de la nebulosa del anillo sur por primera vez. Es un caliente, denso White Darf Star .

como se transformó en una estrella de la estrella blanca . Masa expulsada periódicamente: las conchas del material que ves aquí. Como si estuviera en repetición, se contrajo, se calentó, y luego, incapaz de expulsar más material, pulsado.

En esta etapa, debería haber arrojado sus últimas capas. Entonces, ¿por qué la estrella roja todavía está envuelta en polvo? ¿Se transfirió el material de su compañero? Los investigadores comenzarán a buscar respuestas pronto.

La estrella azul a la derecha en esta imagen también ha dado forma a la escena. Ayuda a agitar el material expulsado. El disco alrededor de las estrellas también se tambalea, disparando espirales de gas y polvo durante largos períodos de tiempo. Esta escena es como presenciar a un rociador giratorio que ha terminado de disparar material en todas las direcciones durante miles de años.

Webb capturó esta escena en la luz de infrarrojo medio, la mayoría de los cuales solo se pueden observar desde el espacio. La luz de infrarrojo medio ayuda a los investigadores a detectar objetos envueltos en polvo, como la estrella roja.

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 MIRI
Exposure Dates 12 June 2022
Filters MIRI>F770W, F1130W, F1280W, F1800W
About The Image
Color Info These images are a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI instrument. Several filters were used to sample 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: F1800W, Green: F1280W, Cyan: F1130W, Blue: F770W
Compass Image The Southern Ring Nebula is a large, semi-transparent oval that is slightly angled from top left to bottom right. Two stars appear at the center very close to one another. The one at left is red, the one at right is light blue. The blue star has tiny diffraction spikes around it. A large translucent red oval surrounds the central stars. From the red oval, shells extend in a mix of colors. The shells that extend to the left and right are red and the shells that extend to the top and bottom are teal. The shells appear to have a filamentous pattern, similar to the surface of a cut citrus fruit. The shells darken in color with distance from the center. The background is black and speckled with tiny bright stars and distant galaxies in a range of colors. For more details, download the Text Description.
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.
