These images are a composite of separate exposures acquired by the WFC3/IR and WFC3/UVIS 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: F555W
Green: F814W
Red: F110W +F160W
