NGC 346 (NIRCam Compass Image)

A star cluster within a nebula. The center of the image contains arcs of orange and pink gas that form a boat-like shape. One end of these arcs points to the top right of the image, while the other end points toward the bottom left. Another plume of orange and pink gas expands from the center to the top left of the image. To the right of this plume is a large cluster of white stars. There are more of these white stars and a few galaxies of different sizes spread throughout the image.

This image of the star cluster NGC 346, captured by Webb’s Near-Infrared Camera (NIRCam), shows compass arrows, scale bar, and color key for reference.

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).

At the lower right is a scale bar labeled 50 light-years, 15 parsecs. The length of the scale bar is approximately one-fifth the total width of the image. Below the image is a color key showing which NIRCam filters were used to create the image and which visible-light color is assigned to each filter. From left to right, NIRCam filters are: F200W is blue; F277W is green; F335M is orange; and F444W is red.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    00:59:04.95
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -72:10:09.15
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Tucana
  • Distance
    DistanceThe 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.
    200,000 light-years away (61,300 parsecs)
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    This image is about 3.9 arcminutes across (240 light-years).

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

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:   Red: F444W, Orange: F335M, Cyan: F277W, Blue: F200W
