About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.11h 40m 48.4s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-26° 29' 11.0"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Hydra
- DistanceDistanceThe 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.10.6 billion light-years (3.2 billion parsecs)

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using several different filters. Two filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F475W (SDSS g) Green: F475W (SDSS g) + F814W (I) Red: F814W (I)
