NGC 604 (NIRCam Compass Image)

An image labeled “James Webb Space Telescope, NGC 604.” At the center of the image is a nebula on the black background of space. The nebula is comprised of clumpy, red, filamentary clouds. At the center-right of the red clouds is a large cavernous bubble, and at the center of the bubble there is a opaque blueish glow with speckles of stars. At the edges of the bubble, the dust is white. There are several other smaller cavernous bubbles at the top of the nebula. At lower left, a white arrow pointing in the 4 o’clock direction is labeled N for north, while an arrow pointing in the 11 o‘clock direction is labeled E for east. At lower right, a scale bar is labeled 250 light-years. At the bottom is a list of NIRCam filters in different colors, from left to right: F090M (blue), F187N (cyan), F200W (green), F335M (orange), F444W (red), and F470N (red).

This image of the NGC 604, captured by Webb’s NIRCam (Near-Infrared Camera) 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.

The scale bar is labeled in light-years, which is the distance that light travels in one Earth-year. (It takes 3 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.

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.
    01:34:33.79
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    30:46:59.0
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Triangulum
  • 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 2.73 million light-years (830,000 parsecs)
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    Image is about 2.1 arcminutes across (about 1,700 light-years)

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

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
