NIRCAM de Webb (cámara de infrarrojo cercano) capturó esta imagen detallada de SN 1987a (Supernova 1987a). En el centro, el material expulsado de la supernova forma una forma de ojo de cerradura. Justo a su izquierda y a la derecha hay crecientes débiles recién descubiertos por Webb. Más allá de ellos, un anillo ecuatorial, formado a partir de decenas expulsadas del material de miles de años antes de la explosión de supernova, contiene puntos calientes brillantes. Exterior a eso es una emisión difusa y dos anillos exteriores débiles. En esta imagen, el azul representa la luz a 1.5 micras (F150W), Cyan 1.64 y 2.0 micras (F164N, F200W), Amarillo 3.23 Microns (F323N), Orange 4.05 Microns (F405N) y Red 4.44 Microns (F4444W).

| About The Data | |
| Data Description | This image was created with Webb data from proposal: (M. Matsuura) |
| Instrument | NIRCam |
| Exposure Dates | 1-2 September 2022 |
| Filters | F150W; F164N; F200W; F323N; F405N; F444W |
| 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 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: F150W, Cyan: F164N, Cyan: F200W, Yellow: F323N, Orange: F405N, 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. |
