Esta imagen de la cámara de infrarrojo casi del telescopio espacial James Webb de la NASA (NIRCAM) presenta la región central de la nube molecular oscura de Chamaeleon I, que reside a 630 años de luz. El material de nube fría y tenue (azul, centro) está iluminado en el infrarrojo por el brillo de los jóvenes y flores de protos ced 110 IRS 4 (naranja, esquina superior izquierda). La luz de numerosas estrellas de fondo, vistas como puntos naranjas detrás de la nube, se puede usar para detectar los hielos en la nube, lo que absorbe la luz de las estrellas que los pasa.
Un equipo internacional de astrónomos ha informado el descubrimiento de diversos compositivos en las regiones más oscuras de una nube molecular fría medida hasta la fecha al estudiar esta región. Este resultado permite a los astrónomos examinar las moléculas heladas simples que se incorporarán a futuros exoplanetas, al tiempo que abren una nueva ventana sobre el origen de moléculas más complejas que son el primer paso en la creación de los bloques de construcción de la vida.

| About The Data | |
| Data Description | This image was created with Webb data from proposal: (M. McClure). |
| Instrument | NIRCam |
| Exposure Dates | 11-12 Aug 2022 |
| Filters | F150W, F410M |
| 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 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: Orange: F150W, Blue: F410M |
| 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. |
