Este mosaico muestra tres de aproximadamente 80 transitorios, u objetos de cambio de brillo, identificados en datos del programa JADES (JWST Advanced Deep Extragalactic Survey). La mayoría de los transitorios son el resultado de estrellas o supernovas en explosión. By comparing images taken in 2022 and 2023, astronomers could locate supernovae that, from our perspective, recently exploded (like the examples shown in the first two columns), or supernovae that had already exploded and whose light was fading away (third column).
The age of each supernova can be determined from its Redshift (designado por "Z"). La luz de la supernova más lejana, a un desplazamiento al rojo de 3.8, se originó cuando el universo tenía solo 1.700 millones de años. Un desplazamiento al rojo de 2.845 corresponde a un tiempo 2.300 millones de años después del Big Bang. The closest example, at a redshift of 0.655, shows light that left its galaxy about 6 billion years ago, when the universe was just over half its current age.

| About The Data | |
| Data Description | This image was created with Webb data from proposal: (D. Eisenstein). Image processing: Alyssa Pagan (STScI). |
| Instrument | NIRCam |
| Exposure Dates | 29 Sept. - 10 Oct. 2022, 2023 |
| Filters | F090W, F115W, F150W, F200W, F277W, F335M, F356W, F410M, F444W |
| 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 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: Blue: F090W + F115W + F150W Green: F200W + F277W + F335M Red: F356W + F410M + 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. |
