Este gráfico muestra el espectro de transmisión obtenido por Webb Observaciones de Exoplanet Rocky GJ 486 b. El análisis del equipo científico muestra toques de vapor de agua; Sin embargo, los modelos de computadora muestran que la señal podría provenir de una atmósfera planetaria rica en agua (indicada por la línea azul) o de los puntos de estrella de la estrella del host enano rojo (indicado por la línea amarilla). Los dos modelos divergen notablemente en longitudes de onda infrarrojas más cortas, lo que indica que se necesitarán observaciones adicionales con otros instrumentos Webb para restringir la fuente de la señal de agua.
La ilustración de fondo de un planeta es un concepto de artista. Webb no ha tomado una imagen del planeta.

| 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. |
| Filters | The camera filters that were used in the science observations. |
| About The Image | |
| Image Credit | The primary individuals and institutions responsible for the content. |
| Publication Date | The date and time the release content became public. |
| Color Info | A brief description of the methods used to convert telescope data into the color image being presented. |
| Orientation | The rotation of the image on the sky with respect to the north pole of the celestial sphere. |
