About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.14h 22m 23.76s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.00° 23' 15.61"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Virgo
- 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.About 72 million light-years (22 million parsecs)
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.The image is 2.4 arcminutes (50,000 light-years or 15,000 parsecs) wide.

This image is a composite of separate exposures acquired by the WFC3 instrument on HST. Several filters were used to sample broad 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: White: F350LP (Long Pass) Blue: F555W (V) Orange: F814W (I)
