Release Date: April 4, 2006
Color: This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using several different filters. Three filters sample broad wavelength ranges; one isolates the light of hydrogen. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
F658N (Hydrogen-alpha) red/orange
F814W (I) red
F555W (V) green
F435W (B) blue
