Los científicos utilizaron el NIRSPEC de James Webb Space Telescope de la NASA (espectrógrafo de infrarrojo cercano) para obtener un espectro de la galaxia distante Jades-GS-Z14-0 para medir con precisión su desplazamiento al rojo y, por lo tanto, determinar su edad. El desplazamiento al rojo se puede determinar a partir de la ubicación de una longitud de onda crítica conocida como la ruptura de Lyman-Alpha. Esta galaxia se remonta a menos de 300 millones de años después del Big Bang.

| 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. |
