This image is a composite mosaic of many separate expposures made by the ACS instrument on the Hubble Space Telescope and the ESO La Silla 2.2 meter telescope using several different 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:
