Release Date: February 6, 2007
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 were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
F475W (g) blue
F625W (r) green
F814W (I) red
Orientation: Hubble Illuminates Cluster of Diverse Galaxies
