This is a compass graphic for the star-forming region NGC 1333. The left half is a color image of NGC 1333 labeled “NGC 1333, HST WFC3/UVIS”. Four filter labels are in blue (F475W), green (F606W), and red (F657N H-alpha plus NII, and F814W). At bottom a scale bar is labeled 0.2 light-years and 43 arcseconds. The right half shows four black-and-white panels in a two-by-two layout. Each panel is a view of NGC 1333 in an individual filter. At top left is F475W; at top right is F606W; at bottom left is F657N; at bottom right is F814W.

| About The Data | |
| Data Description | The HST observations include those from program 17266 (C. Britt) |
| Instrument | WFC3/UVIS |
| Exposure Dates | December 2022 to March 2023 |
| Filters | F475W, F606W, F657N, F814W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the WFC3 instrument on the Hubble Space Telescope. Several filters were used to sample wide and narrow 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: F475W, Green: F606W, Red: F657N and F814W |
| 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. |
