Esta imagen de la NACRIM (cámara de infrarrojo cercano) de James Webb del telescopio de James Webb (cámara de infrarrojo) de la región que formaba estrellas NGC 604 muestra cómo los vientos estelares de estrellas jóvenes brillantes y calientes escallan cavidades en gas y polvo circundantes.
Las rayas de color naranja brillante en esta imagen significan la presencia de las moléculas basadas en carbono conocidas como aromatices hidrocríesicos poliícolas, o páhs. A medida que viaja más lejos de las cavidades inmediatas de polvo donde se está formando la estrella, el rojo más profundo significa hidrógeno molecular. Este gas más frío es un ambiente principal para la formación de estrellas. El hidrógeno ionizado por la radiación ultravioleta aparece como un brillo fantasmal blanco y azul.
ngc 604 se encuentra en la galaxia triangulum (M33), a 2.73 millones de años luz de la Tierra. Brinda una oportunidad para que los astrónomos estudien una alta concentración de estrellas muy jóvenes y masivas en una región relativamente cercana.

| About The Data | |
| Data Description | This image was created with Webb data from proposal: (M. Marin). Image processing: Alyssa Pagan (STScI). |
| Instrument | NIRCam |

| Filters | F090W, F187N, F200W, F335M, F444W, F470N |
| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample varying 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, Cyan: F187N, Green: F335M, Red: F444W+F470N |

| 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. |
