IC 348 (NIRCam Compass Image)

An image showing wispy pink-purple filaments and a scattering of stars.

This image of star cluster IC 348, 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).

The scale bar is labeled in light-years, which is the distance that light travels in one Earth-year. (It takes 0.1 years for light to travel a distance equal to the length of the scale bar.) One light-year is equal to about 5.88 trillion miles or 9.46 trillion kilometers. The field of view shown in this image is approximately 0.5 light-years across and 0.8 light-years high.

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.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    03:44:34.28
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    +32:09:43.10
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Perseus
  • 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.
    About 1,000 lightyears
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    This image is about 1.9 arcminutes across (.6 lightyears)

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:  Blue: F277W, Green: F360M, Red: F444W
