This image is a composite of many separate exposures made by the WFC3/UVIS instrument on the Hubble Space Telescope using three different filters. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
Blue: F467N (46nm)
Green: F631N (63nm)
Red/orange: F845M (84nm)
