nota del editor : esta publicación destaca los datos de Webb Science in Progress, que aún no ha pasado por el proceso de revisión de pares.
mediante la combinación de datos de la telescopio espacial James White de la NASA y los temascopios espaciales de la NASA, los investigadores, los investigadores, los investigadores, los investigadores de la luz de la NASA. Galaxia espiral a la derecha e identificar los efectos del polvo interestelar en la galaxia espiral. Esta imagen de Galaxy Par VV 191 incluye luz de infrarrojo cercano de Webb y luz ultravioleta y visible de Hubble.
Los datos de infrarrojo cercano de Webb también nos muestran los brazos espirales más largos y extremadamente polvorientos de la Galaxia con mucho más detalle, dándoles una apariencia de superposición con el bulto central de la galaxia elíptica blanca blanca brillante a la izquierda. Aunque las dos galaxias en primer plano están relativamente cercanas astronómicamente hablando, no están interactuando activamente.
¡No pasen por alto el escenario de fondo! Al igual que muchas imágenes de Webb, esta imagen de VV 191 muestra muchas galaxias que se encuentran grandes distancias. Por ejemplo, dos espirales irregulares en la parte superior izquierda de la galaxia elíptica tienen tamaños aparentes similares, pero aparecen en colores muy diferentes. Es probable que uno sea muy polvoriento y el otro muy lejos, pero los investigadores deben obtener datos conocidos como specTra a determinar a determinar a determinar a determinar a determinar que.

| About The Data | |
| Data Description | This image was created from JWST and HST data from proposals: (R. A. Windhorst), (B. W. Holwerda) ; (B. W. Holwerda) |
| Instrument | HST>WFC3/UVIS JWST>NIRCam |
| Exposure Dates | 19 June 2015, 16 Dec 2018, 2 July 2022 |
| Filters | HST> F336W, F606W JWST> F356W, F150W, F090W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope and the Hubble Space Telescope using the NIRCam and WFC3/UVIS instruments respectively. Several filters were used to sample infrared, visible and ultraviolet 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: F356W Yellow: F150W, Green: F090W, Blue: F336W + F606W |
| 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 | |
| Image Credit | The primary individuals and institutions responsible for the content. |
| Publication Date | The date and time the release content became public. |
| Color Info | A brief description of the methods used to convert telescope data into the color image being presented. |
