Cassiopeia A (imagen de Nircam)

Una nueva imagen de alta definición de la NASA's James Webb Space Telescope (cámara de infrarrojo cercano) revela detalles intrincados de la supernova remanente de cassiopeia a (Cas a), y muestra la carcasa expansiva de los golpes de material en la estrella de la estrella de la estrella de la estrella y los colores más livianos de los colores más livianos de la red de los colores más livianos de la imagen de los colores más livianos de la cebada de los accesorios. Concha interior del remanente de supernova. Estos pequeños nudos de gas, compuestos por azufre, oxígeno, argón y neón de la estrella misma, solo son detectables por la resolución exquisita de Nircam, y brindan a los investigadores una pista de cómo la estrella moribunda se rompió como el vidrio cuando explota. Esto marca donde el material expulsado de la estrella explotada se está embarcando en el material circunstelar circundante. Los investigadores dicen que este color blanco es ligero de la radiación sincrotrón, que se genera por partículas cargadas que viajan a velocidades extremadamente altas en espiral alrededor de las líneas de campo magnético.

También hay varios ecos de luz visibles en esta imagen, especialmente en la esquina inferior derecha. Aquí es donde ha alcanzado la luz de la explosión de la estrella, y está calentando el polvo distante, que está brillando a medida que se enfría.

About The Data

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
Compass Image Cassiopeia A, a circular-shaped cloud of gas and dust with complex structure. The inner shell is made of bright pink and orange filaments studded with clumps and knots that look like tiny pieces of shattered glass. Around the exterior of the inner shell, particularly at the upper right, there are curtains of wispy gas that look like campfire smoke. The white smoke-like material also appears to fill the cavity of the inner shell, featuring structures shaped like large bubbles. Around and within the nebula, there are various stars seen as points of blue and white light. Outside the nebula, there are also clumps of yellow dust, with a particularly large clump at the bottom right corner that appears to have very detailed striations.
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.
