MACS 0416 (Hubble ACS y WFC3 + Imagen de Webb Nircam)

Esta vista pancromática del clúster Galaxy MacS0416 se creó combinando observaciones infrarrojas del telescopio espacial James Webb de la NASA con datos de luz visible del telescopio espacial Hubble de la NASA. Para hacer la imagen, en general, las longitudes de onda más cortas de la luz eran azules codificadas por colores, las longitudes de onda más largas rojo y las longitudes de onda intermedias de verde. La cobertura de longitud de onda resultante, de 0.4 a 5 micras, revela un paisaje vívido de galaxias que podría describirse como una de las vistas más coloridas del universo jamás creado.

MacS0416 es un grupo de galaxia ubicado a unos 4.300 millones de años luz de la Tierra, lo que significa que la luz ahora vemos el clúster cortos después de la formación de nuestro sistema solar. Este clúster magnifica la luz de las galaxias de fondo más distantes a través de Lensing gravitacional . Como resultado, el equipo de investigación ha podido identificar supernovas magnificadas e incluso estrellas individuales muy magnificadas.

Esos colores dan pistas sobre las distancias de la galaxia: las galaxias más azules están relativamente cercanas y a menudo muestran una intensa formación de estrellas, como lo detectan mejor por Hubble, mientras que las galaxias rojizas tienden a estar más distantes, o más que contienen una cantidad intensa de polvo, tal como detectado por el Hubble. La imagen revela una gran cantidad de detalles que solo son posibles para capturar combinando la potencia de ambos telescopios espaciales.

En esta imagen, el azul representa datos a longitudes de onda de 0.435 y 0.606 micras (filtros Hubble F435W y F606W); El cian es 0.814, 0.9 y 1.05 micras (filtros de hubble F814W y F105W y Webb Filter F090W); El verde es 1.15, 1.25, 1.4, 1.5 y 1.6 micras (Filtros Hubble F125W, F140W y F160W, y los filtros Webb F115W y F150W); El amarillo es 2.00 y 2.77 micras (filtros Webb F200W y F277W); Naranja es 3.56 micras (Filtro Webb F356W); y el rojo representa datos a 4.1 y 4.44 micras (Filtros Webb F410M y F444W).

About The Image
Color Info These images are a composite of separate exposures acquired by the Hubble and Webb Space Telescopes using the ACS, WFC3, and NIRCam instruments. Multiple filters were used to sample broad and narrow 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 and F410M, Orange: F356W, Yellow: F277W and F200W, Green: F160W, F150W, F140W, F125W, F115W, Cyan: F090W, F105W, F814W, Blue: F606W, F435W
Compass Image A field of galaxies on the black background of space. In the middle, stretching from left to right, is a collection of dozens of yellowish spiral and elliptical galaxies that form a foreground galaxy cluster. They form a rough, flat line along the center. Among them are distorted linear features, which mostly appear to follow invisible concentric circles curving around the center of the image. The linear features are created when the light of a background galaxy is bent and magnified through gravitational lensing. At center left, a particularly prominent example stretches vertically about three times the length of a nearby galaxy. A variety of brightly colored, red and blue galaxies of various shapes are scattered across the image, making it feel densely populated. Near the center are two tiny galaxies compared to the galaxy cluster: a very red edge-on spiral and a very blue face-on spiral, which provide a striking color contrast.
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.
