The image is a composite of separate exposures made by Hubble Space Telescope ACS detectors, the ESO's Very Large Telescope (VLT), and the Chandra ACIS detector. Hubble provides the central, most detailed part of the image, while the VLT, which has a wider field of view, provides the outer parts of the image. A map of the cluster's dark matter distribution has also been applied to the image. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Dark Matter Map; HST F438W (B); VLT B blue HST F606W (V); VLT R green Chandra X-ray data; HST F814W (I); VLT I red

The image was created from Hubble data from proposal 11689: R. Dupke (University of Michigan), N. Benitez (Astrophysical Institute of Andalucía, Spain), J. Krick (California Institute of Technology), B. Bregman (University of Michigan), D. Coe (STScI), L. Sodre (University of Sao Paulo), T. Broadhurst (Tel Aviv University, Wise Observatory), and R. Bernstein (University of California, Santa Cruz).

The science team is led by J. Merten (Institute for Theoretical Astrophysics, Heidelberg/Astronomical Observatory of Bologna). Instrument: ACS/WFC Exposure Date(s): October 27-30, 2009 Exposure Time: 12 hours Filters: F438W (B), F606W (V), and F814W (I)
