About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.14h 34m 37.02s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.59° 20' 16.11"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Draco
- 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.130 million light-years (40 million parsecs)

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.
This image is a composite of separate exposures acquired by the WFC3/UVIS instrument. Several filters were used to sample various wavelengths. 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: F555W (V), Green: F350LP Red: F814W (I)
Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
