Esta imagen de Cartwheel and Sur Companion Galaxies es un compuesto de Webb cámaras cercanas a la entrada Instrumento de la infrarroja media (miRI), que revela detalles que son difíciles de ver solo en las imágenes individuales. hace millones de años. La rueda de carreta está compuesta de dos anillos, un anillo interno brillante y un colorido anillo exterior. Ambos anillos se expanden hacia afuera desde el centro de la colisión como ondas de choque.
Sin embargo, a pesar del impacto, gran parte del carácter de la gran galaxia espiral que existía antes de que permanezca la colisión, incluidos sus brazos rotativos. Esto lleva a los "radios" que inspiraron el nombre de la galaxia de las ruedas de carreras, que son las rayas rojas brillantes que se ven entre los anillos internos y externos. Estos brillantes tonos rojos, ubicados no solo en toda la rueda de carreta, sino también en la galaxia espiral complementaria en la parte superior izquierda, son causados por polvo brillante y rico en hidrocarburos.
En esta imagen compuesta de infrarrojo cercano y medio, los datos de Miri son rojos de color, mientras que los datos de Nircam son azules de color, naranja y amarillo. En medio de los remolinos rojos de polvo, hay muchos puntos azules individuales, que representan estrellas o bolsillos individuales de la formación de estrellas. Nircam también define la diferencia entre las poblaciones de estrellas más antiguas y el polvo denso en el núcleo y las poblaciones de estrellas más jóvenes fuera de ella.
Las observaciones de Webb capturan la rueda de carreta en una etapa muy transitoria. La forma que la Galaxia Cartwheel eventualmente tomará, dadas estas dos fuerzas competidoras, sigue siendo un misterio. However, this snapshot provides perspective on what happened to the galaxy in the past and what it will do in the future.
NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.
MIRI was contributed by ESA and NASA, with the instrument designed and built by a consortium of nationally funded European Institutes (The MIRI European Consorcio) en asociación con JPL y la Universidad de Arizona.

| 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 MIRI and NIRCam instruments. 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: F444W + F356W Orange: F770W + F1000W + F1280W + F1800W Yellow: F277W Green: F200W Blue: F150W + 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. |
