Galaxy HUDF-JD2 – Near Infrared

Galaxy HUDF-JD2 - Near Infrared
The galaxy was detected using Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS). But at near infrared wavelengths, it is very faint and red.

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.
