Cassiopeia A (imagen de Miri)

Cassiopeia A (imagen de Miri)

cassiopeia A (CAS A) es un remanente de supernova ubicado a unos 11,000 años luz de la Tierra en la constelación de Cassiopeia. Abarca aproximadamente 10 años luz. Esta nueva imagen usa datos de Webb Instrumento interfremado en medio de Remnant (Miri) para revelar CAS a una nueva luz.

En la parte superior e izquierda, se encuentran cortinas de material que aparecen naranja y rojo debido a la emisión del polvo cálido. Esto marca donde el material expulsado de la estrella explotada se está embarcando en el material circunstelar circundante. 

Interior a esta capa externa se encuentra filamentos moteados de rosa brillante con grupos y nudos. Esto representa el material de la estrella misma, y ​​probablemente brilla debido a una mezcla de varios elementos pesados ​​y emisión de polvo. El material estelar también se puede ver como mechas más débiles cerca del interior de la cavidad.

Un bucle representado en verde se extiende a través del lado derecho de la cavidad central. Su forma y complejidad son inesperadas y desafiantes para que los científicos entiendan.

Esta imagen combina varios filtros con el color rojo asignado a 25.5 micras (F2550W), naranja a 21 micrones (F2100W), naranja a 18 micras (F1800W), amarillo a 12.8 micras (F1280W), verde a 11.3 micrones (F1130 WWW), cyan to 10 Microns a 10.8 microns (F1280W), Green to 11.3 Microns (F1130 Ww), Cyan to 10 Microns, Cyan to 10 Microns (Cyan to 10 Micron (F1000W), azul claro a 7.7 micras (F770W) y azul a 5.6 micras (F560W). Los datos provienen del programa General Observer 1947 .  

MIRI was contributed by NASA and ESA, with the instrument designed and built by a consortium of nationally funded European Institutes (the MIRI European Consortium) and NASA’s Jet Propulsion Laboratory, in partnership with the University of Arizona.

About The Data
Data Description This image was created with Webb data from proposal: (D. Milisavljevic).
Instrument MIRI
Exposure Dates August 4, 2022

About The Image
Color Info These images are a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI instrument. Several filters were used to sample wide 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: F560W, Light Blue: F770W, Cyan: F1000W, Green: F1130W, Yellow: F1280W, Orange: F1800W, Red: F2100W+F2550W
Compass Image A roughly square image is rotated clockwise about 45 degrees, with solid black in the corners on the top left, top right, bottom left, and bottom right. Within the image is a circular-shaped nebula with complex structure. On the circle’s exterior, particularly at the top and left of the image, lie curtains of material glowing orange. Interior to this outer shell lies a ring of mottled filaments of bright pink studded with clumps and knots. At center right, a greenish loop extends from the right side of the ring into the central cavity. Translucent wisps of blue, green, and red appear throughout the image.
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.
