About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.11h 49m 35.5s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.22° 24' 4.21"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Leo
- 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.13.2 billion light-years (4 billion parsecs or redshift z = 9.6)

This image is a composite of separate exposures acquired by the ACS and WFC3 instruments. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated: Blue: ACS/WFC F435W (B) + F475W (g) + F555W (V) Green: ACS/WFC F606W (V) + F625W (r) + F775W (I) + Red: ACS/WFC F814W (I) + F850LP (z) + WFC3/IR F105W (Y) + F110W (YJ) + F125W (J) + F140W (JH) + F160W(H)
