Six near-infrared images from NIRCam (the Near-Infrared Camera) aboard the James Webb Space Telescope make up this composite of Herbig-Haro 46/47.
The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).
This image shows invisible near-infrared wavelengths of light that have been translated into visible-light colors. The color key shows which NIRCam filters were used when collecting the light. The color of each filter name is the visible-light color used to represent the infrared light that passes through that filter.
The scale bar is labeled in arcminutes, which is a measure of angular distance on the sky. One arcminute is equal an angular measurement equal to 1/60 of one degree. (The full Moon has an angular diameter of about 30 arcminutes.) The actual size of an object that covers one arcminute on the sky depends on its distance from the telescope.

| About The Data | |
| Data Description | This image was created from JWST data from proposal: (K. Pontoppidan) |
| Instrument | NIRCam |
| Exposure Dates | May 24, 2023 |
| Filters | F115W, F187N, F200W, F335M, F444W, F470N |
| 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: Blue: F115W, Cyan: F187N, Green: F200W, Yellow: F335M, Orange: F444W, Red: 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. |
