El telescopio espacial James Webb ha devuelto imágenes extraordinariamente detalladas y Specra de las galexas que existían solo el universo que existían solo el universo que existen. años. "En la imagen de infrarrojo cercano de Webb, podemos ver estructuras en cada galaxia individual que detectó el telescopio", compartió Jorryt Matthee de Eth Zürich. "Webb nos está mostrando la juventud aventurera de estas primeras galaxias".
Estas galaxias se ven más caóticas que las del universo cercano: son gruesas y a menudo alargadas. Estas galaxias también son más jóvenes y están formando activamente estrellas. Las estrellas que se detectaron en Webb son más masivas, lo que puede conducir a una abundancia de colorido supernovae disparos de la vista en estas galaxias. Los resultados fueron anunciados por miembros de galaxias de línea de emisión y gas intergaláctico en la época de reionización (EIGER) equipo. Webb’s nircam (cámara infrente cercana) conocidos como espectros ayudó al equipo a definir completamente 117 galaxias en este campo.

| About The Data | |
| Data Description | This image was created with Webb data from proposal: (S. Lilly) |
| Instrument | NIRCam |
| Exposure Dates | 22 Aug 2022 |
| Filters | F115W, F200W, F356W |
| 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: F115W Green: F200W Red: F356W |
| 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. |
