Wolf-Rayet Stars son productores de polvo eficientes, y el mid-marrium instrument (miri) en nasabbebebebebebebeSaSaSaSa's James aparece a James de naSesc. Gran efecto. El polvo cósmico más frío brilla en las longitudes de onda más largas de infrarrojo medio, mostrando la estructura de la nebulosa de WR 124. La nebulosa de 10 años de ancho está hecha de material expulsado de la estrella envejecida en eyecciones aleatorias y del polvo producido en la turbulencia resultante. Esta brillante etapa de pérdida de masa precede a la eventual supernova de la estrella, cuando la fusión nuclear en su núcleo se detiene y la presión de la gravedad hace que se colapse en sí mismo y luego explote. Como Miri demuestra aquí, Webb ayudará a los astrónomos a explorar preguntas que anteriormente solo se dejaron a la teoría, sobre cuánto crean las estrellas de polvo como esta antes de explotar en una supernova, y cuánto de ese polvo es lo suficientemente grande como para sobrevivir a la explosión y servir como bloques de construcción de futuras estrellas, planetas y moléculas complejas.
En esta imagen, el rojo se asigna a longitudes de onda de 12.8 y 18 micras (f1280w, f1800w), verde a 11.3 microns (f1130w) y azul a 7.7 microns (f770w).

| 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. |

| Filters | F770W; F1130W; F1280W; F1800 |
| 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 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: F1280W + F1800W, Green: F1130W, Blue: F770W |
| 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. |
