Composite of visible-light (Hubble) and infrared (Spitzer) images of the distant galaxy HUDF-JD2 in the Hubble Ultra Deep Field.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    3h 32m 28s.74s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -27° 48' 39".9
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Fornax
  • 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.
    This galaxy has a redshift of z = 6.5.
