This image was created from HST data from the following proposal 10495: B. McNamara (Ohio University), M. Wise (Massachusetts Institute of Technology), and P. Nulsen (Harvard-Smithsonian Astrophysical Observatory).
This image is a composite of many separate exposures made by several different instruments from the three missions listed above. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
Blue (CXO): X-ray
Yellow-green (HST): visible
Red (VLA): radio
