This image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope using two different cameras and filters isolating the light of specific elements or of specific broad wavelength ranges. The color arises by assigning different hues (colors), to each monochromatic image. In this case, the colors are: blue WFC3/UVIS F606W, green WFC3/IR F110W, orange/red: WFC3/IR F160W.
