Sagitario C (imagen de Nircam)

La vista completa del instrumento Nircam (cámara de infrarrojo cercano) del telescopio de James Webb revela una porción de 50 años de ancho del centro de la Vía Láctea. Se estima que 500,000 estrellas brillan en esta imagen de la región Sagitario C (SGR C), junto con algunas características aún no identificadas. 

Una vasta región de hidrógeno ionizado, que se muestra en Cyan, envuelve un

Las nubes infrarrojas más pequeñas salpican la escena, apareciendo como agujeros en el campo de estrellas. 

Los investigadores dicen que solo han comenzado a profundizar en la riqueza de datos de alta resolución sin precedentes que Webb ha proporcionado en esta región, y muchas características tienen un estudio detallado. Esto incluye las nubes de color rosa en el lado derecho de la imagen, que nunca se han visto con tal detalle.

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 specific 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: F162M, Cyan: F405N, Orange: F360M, Red: F470N
Compass Image a funnel-shaped region of space appears darker than its surroundings with fewer stars. It is wider at the top edge of the image, narrowing towards the bottom. Toward the narrow end of this dark region a small clump of red and white appears to shoot out streamers upward and left. A large, bright cyan-colored area surrounds the lower portion of the funnel-shaped dark area, forming a rough U shape. The cyan-colored area has needle-like, linear structures and becomes more diffuse in the center of the image. The right side of the image is dominated by clouds of orange and red, with a purple haze.
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.
