El telescopio espacial James Webb ha observado la mejor evidencia hasta el momento para la emisión de una estrella de neutrones en el sitio de una supernova conocida y recientemente observada conocida como SN 1987a. A la izquierda hay una imagen Nircam (cámara de infrarrojo cercano) lanzado en 2023 . La imagen en la parte superior derecha muestra luz del argón ionizado individual (argón II) capturado por el modo del espectrógrafo de resolución media (MRS) de MIRI (instrumento de infrarrojo medio). La imagen en la parte inferior derecha muestra la luz del argón múltiple ionizado capturado por el NIRSPEC (espectrógrafo de infrarrojo cercano). Ambos instrumentos muestran una fuerte señal desde el centro del remanente de supernova. Esto indicó al equipo científico que existe una fuente de radiación de alta energía allí, muy probablemente una estrella de neutrones.

| R.A. Position | 05:35:28.03 |
| Dec. Position | -69:16:11.8 |
| Constellation | Dorado |
| Distance | Approximately 160,000 light-years away |
| About The Data | |
| Data Description | This image was created with Webb data from proposal: (M. Matsuura) and (G. Wright). Image Processing: Alyssa Pagan (STScI) |
| Instrument | NIRCam, MIRI, NIRSpec |
| Exposure Dates | 1-2 September 2022, 16 July 2022 |
| Filters | NIRCam > F150W; F164N; F200W; F323N; F405N; F444W |
| About The Image | |
| Color Info | The main 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. |
