Little Red Dot Abell2744-QSO1 (NIRCam Compass Image)

Image titled James Webb Space Telescope, Pandora’s Cluster, Little Red Dot Abell2744-QSO1 with compass arrows, scale bar, and color key. A deep field image showing objects of different size, color, and shape. Three tiny, red circular objects are called out with small white boxes, and enlarged in pullouts labeled from top to bottom: QSO1A, QSO1B, and QSO1C. In the bottom left corner of the image are compass arrows indicating the orientation of the image on the sky. The east arrow points toward 10 o’clock. The north arrow points toward 1 o'clock. At the bottom right corner of the image is a scale bar labeled 15 arcseconds. The image width is about 5.5 times the length of the scale bar. 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: F115W (blue), F150W (blue), F200W (green), F277W (green), F356W (red), F444W (red).

Image of Abell 2744 (Pandora's Cluster) and Little Red Dot Abell2744-QSO1, captured by Webb’s NIRCam, with 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 arcseconds, which is a measure of angular distance across the sky. For reference: There are 60 arcseconds in 1 arcminute, and 60 arcminutes in 1 angular degree. The full sky, surrounding the entire Earth, is 360 angular degrees. The full Moon has an angular diameter of about 30 arcminutes (0.5 angular degrees).

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.
    00:14:18.25
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -30:22:46.04
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Sculptor
  • 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 3.5 billion light-years to cluster and 13.1 billlion light-years to QSO1 (z = 7.04)
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    The image is 4.3 arcminutes across

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: F115W+F150W, Green: F200W+F277W, Red: F356W+F444W

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
