Casiopeia A (nircam y Miri lado a lado)

Esta imagen proporciona una comparación de lado a lado de la supernova remanente cassiopeia a (CAS a) como capturada por la NASA la NASA Webb Space Telescope (cámara de infrarrojo cercano) y Miri (instrumento de infrarrojo medio).

A primera vista, la imagen de NIRCAM de Webb parece menos colorida que la imagen de miRi en general, sin embargo, esto es solo que se debe a los materiales que se debe a la visión de lo que se debe altera. El objeto está emitiendo su luz. La imagen de Nircam parece un poco más nítida que la imagen Miri debido a su mayor resolución.

Las afueras de la caparazón interna principal, que apareció como un naranja profunda y rojo en la imagen de Miri, parece humo de una fogata en la imagen de Nircam. Esto marca donde la ola de explosión de supernova se está embarcando en el material circunstelar circundante. El polvo en el material circunstelar es demasiado fresco para detectarse directamente a las longitudes de onda de infrarrojo cercano, pero se ilumina en el infrarrojo medio.

tampoco se ve en la vista de infrarrojo cercano es el bucle de la luz verde en la cavidad central de CAS A que brillaba en la infrarrición media, apodada el monstruo verde por el equipo de investigación. Sin embargo, los agujeros circulares visibles en la imagen de Miri dentro del monstruo verde se describen ligeramente en la emisión blanca y morada en la imagen de Nircam.

About The Data
Data Description This image was created with Webb data from proposal: (D. Milisavljevic).
Instrument NIRCam
Exposure Dates 05 November 2022
Filters F162M, F356W, F444W
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, Green: F356W, Red: F444W
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.
