Serpens (nircam)

En esta imagen de la nebulosa Serpens de la cámara de infrarrojo cercano (NIRCAM) en el telescopio espacial James Webb de la NASA, los astrónomos encontraron una agrupación de salidas protoStellar alineadas dentro de una pequeña región (la esquina superior izquierda). En la imagen de Webb, estos chorros están significados por rayas brillantes y gruesas que aparecen rojos, que son ondas de choque del chorro que golpea el gas y el polvo circundantes.

La nebulosa serpens, ubicada 1,300 años luz de la tierra, es el hogar de un grupo de recién formación de estrellas (~ 100,000 años), que finalmente crecerá a la masa de nuestra masa de la masa de la masa de la masa de la masa. Descubrimientos coincidentes, incluido el aleteo "bat shadow", que obtuvieron su nombre cuando los datos de 2020 de la telescopio de Hubble de la NASA revelaron una sombra de la estrella de la estrella que entra en el planet a Flap, o el desplazamiento. Esta característica es visible en el centro de la imagen Webb.

A la derecha de la "sombra de murciélago" se encuentra otra característica intrigante: una grieta en forma de ojo, que parece que una estrella está estallando. Sin embargo, los astrónomos dicen que la apariencia puede estar engañando aquí. Esto podría ser solo gases de diferentes densidades en capas una encima de la otra, similar a lo que se ve en el famoso pilares de la creación .

y a la derecha de eso es extremadamente oscuro. Este gas y polvo son tan densos en comparación con el resto de la región, no hay luz de infrarrojo cercano. (Stsci)

About The Image
Color Info This image is a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample medium 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: F140M, Cyan: F210M, Orange: F360M, Red: 480M  
Compass Image A rectangular image with black vertical rectangles at the bottle left and top right to indicate missing data. A young star-forming region is filled with wispy orange, red, and blue layers of gas and dust. The upper left corner of the image is filled with mostly orange dust, and within that orange dust, there are several small red plumes of gas that extend from the top left to the bottom right, at the same angle. The center of the image is filled with mostly blue gas. At the center, there is one particularly bright star, that has an hourglass shadow above and below it. To the right of that is what looks a vertical eye-shaped crevice with a bright star at the center. The gas to the right of the crevice is a darker orange. Small points of light are sprinkled across the field, brightest sources in the field have extensive eight-pointed diffraction spikes that are characteristic of the Webb Telescope.
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.
