Izquierda: en 2016, el telescopio espacial Hubble de la NASA vio una supernova de imagen multiplicada, apodada Supernova Requiem, en una galaxia distante lentes por el clúster de galaxias intermedio MacS J0138. Se ven tres imágenes de la supernova, y se espera que llegue una cuarta imagen en 2035. En esta imagen de infrarrojo cercano, la luz a 1.05 micras está representada en azul y 1.60 micras es naranja. Derecha: en noviembre de 2023, el telescopio espacial James Webb de la NASA identificó una segunda supernova de imagen multiplicada en la misma galaxia utilizando su instrumento NirCam (cámara de infrarrojo cercano). Este es el primer sistema conocido en producir más de una supernova de imágenes multiplicadas.

| About The Data | |
| Data Description | This image was created with Webb data from proposal: (J. Pierel) and HST data from proposal: (A. Newman) Image Processing: Alyssa Pagan |
| Instrument | Hubble> WFC3/IR Webb> NIRCam |
| Exposure Dates | 18-19 July 2016, 05 December 2023 |

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the Hubble Space Telescope using the WFC3/IR instrument and the James Webb Space Telescope using the NIRCam 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: Left (Hubble) = Cyan: F105W, Orange: F160W Right (Webb) = Blue: F115W+F150W, Green: F200W+F277W, Red: F356W+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. |
| About The Data | |
| Data Description |
|
| Instrument | The science instrument used to produce the data. |
| Exposure Dates | The date(s) that the telescope made its observations and the total exposure time. |
