About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    09h 19m 26.22s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    27° 20' 51.0"
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Cancer
  • 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.
    z (quasar galaxy) = 0.209, z (lensing source) = 0.558

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 WFC3 UVIS instrument. Several filters were used to sample various wavelength and energy 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 (B) Orange: F814W (I)
