This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges, while one filter was used to sample a narrow wavelength band. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F435W (B)


F555W (V)


F656N (Halpha + [N II]) and F814 (I)
