About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.06:15:49.7
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-57:46:41
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Pictor
- 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.Galaxy Cluster: 7.7 billion light-years; Lensed Galaxy: 13.243 billion light-years
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.Image is 2 arcmin across (about 4.5 million light-years at the distance of the cluster)

These images are a composite of separate exposures acquired by the ACS/WFC and WFC3/IR instruments on the Hubble Space Telescope. Several filters were used to sample various 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: F606W Green: F814W Red: F105W + F125W + F140W + F160W
