Esta imagen tomada por la NIRCAM de Webb (cámara de infrarrojo cercano) muestra una parte de la nebulosa Orion conocida como la barra de Orión. Es una región donde la luz ultravioleta energética del grupo de trapecio, ubicado en la esquina superior izquierda, interactúa con nubes moleculares densas. La energía de la radiación estelar está erosionando lentamente la barra de Orion, y esto tiene un profundo efecto en las moléculas y la química en Protop Los discos que se han formado alrededor de las estrellas recién nacidas aquí.
Dentro de esta imagen se encuentra un joven sistema estrella conocido como D203-506, que tiene un disco protoplanetario. Los astrónomos usaron Webb para detectar una molécula de carbono conocida como catión metílico en ese disco por primera vez. Esa molécula es importante porque ayuda a la formación de moléculas más complejas basadas en carbono.

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam/MIRI 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: Purple: 1.4, 1.62 microns; Blue: 1.64, 1.82 microns; Cyan: 1.87, 2.1 microns; Green: 2.12, 2.77 microns; Yellow: 3.0 microns; Orange: 3.23, 3.35 microns; Red: 4.7, 4.8 microns |
| 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. |
