MacS 0416 (Hubble y Webb comparado)

Esta comparación de lado a lado del clúster Galaxy MacS0416, como lo ve el telescopio espacial Hubble en luz óptica (izquierda) y el telescopio espacial James Webb en luz infrarroja (derecha) revela diferentes detalles. Ambas imágenes presentan cientos de galaxias, sin embargo, la imagen Webb muestra galaxias que son invisibles o que apenas son visibles en la imagen del Hubble. Esto se debe a que la visión infrarroja de Webb puede detectar galaxias demasiado distantes o polvorientas para que Hubble lo vea. (La luz de las galaxias distantes es redhshifted de la vez. El tiempo de exposición total para Webb fue de aproximadamente 22 horas, en comparación con 122 horas de tiempo de exposición para la imagen del Hubble.

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.
