El telescopio espacial James Webb de la NASA ha mirado a la nebulosa del cangrejo en la búsqueda de respuestas sobre los orígenes del remanente de supernova. El NIRCAM de Webb (cámara de infrarrojo cercano) y Miri (instrumento de infrarrojo medio) han revelado nuevos detalles en luz infrarroja.
Similar a la imagen de longitud de onda óptica de Hubble lanzada en 2005, con Webb el remanente aparece compuesto de una estructura nítida y similar a la copa de los filamentos rojos rojos de gas de gas de gas de los sulfures fluidos. Entre las crestas interiores del remanente, blancas amarillas y verdes, forman estructuras de bucle a gran escala, que representan áreas donde residen las partículas de polvo.
El área dentro está compuesta de material lechoso translúcido. Este material blanco es la radiación sincrotrón, que se emite a través del espectro electromagnético, pero se vuelve particularmente vibrante gracias a la sensibilidad y la resolución espacial de Webb. Se genera por partículas aceleradas a velocidades extremadamente altas a medida que enrollan alrededor de las líneas de campo magnético. Trace la radiación sincrotrón en la mayoría del interior de la nebulosa de cangrejo.
Localice los mechones que siguen un patrón similar a una onda en el medio. En el centro de esta estructura en forma de anillo hay un punto blanco brillante: una estrella de neutrones que gira rápidamente. Más allá del núcleo, siga las cintas blancas delgadas de la radiación. Los rizos curvos se agrupan estrechamente, siguiendo diferentes direcciones que imitan la estructura del campo magnético del pulsar. Tenga en cuenta cómo ciertos filamentos de gas son de color más azules. Estas áreas contienen hierro ionizado individual (hierro II).

| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam and MIRI instruments. 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, Light Blue: F480M, Cyan: F560W, Green: F1130W, Orange: F1800W, Red: F2100W |

| 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. |
