Esta imagen infrarroja del telescopio espacial James Webb de la NASA (también llamado Webb o JWST) fue tomada por el NIRCAM (cámara de infrarrojo cercano) para la encuesta extragaláctica profunda de JWST, o Jades, programa. Los datos de NIRCAM se usaron para determinar qué galaxias estudiar más con observaciones espectroscópicas. Se determinó que una de esas galaxias, Jades-GS-Z14-0 (que se muestra en la extracción), estaba en un desplazamiento al rojo de 14.32 (+0.08/-0.20), lo que lo convierte en el actual titular de la galaxia conocida más distante. This corresponds to a time less than 300 million years after the big bang.
In the background image, blue represents light at 0.9, 1.15, and 1.5 microns (filters F090W + F115W + F150W), green is 2.0 and 2.77 microns (F200W + F277W), and red is 3.56, 4.1, and 4.44 microns (F356W + F410M + F444W). La imagen de extracción muestra luz a 0.9 y 1.15 micras (F090W + F115W) como azul, 1.5 y 2.0 micras (F150W + F200W) como verde y 2.77 micras (F277W) como rojo. href = "https://webbtelescope.org/contents/early-highlights/nasas-james-webb-space--telescope-finds-most-distant- conocido-galaxy"> leer la historia.

| About The Data | |
| Data Description | This image was created with Webb data from proposal: (D. Eisenstein) |
| Instrument | NIRCam |
| Exposure Dates | 29 Sept. - 10 Oct. 2022 |
| Filters | F090W, F115W, F150W, F200W, F277W, F356W, F410M, F444W |
| 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 wide 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: Blue: F090W + F115W + F150W Green: F200W + F277W Red: F356W + F410M + F444W |
| 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. |
