| About The Image | |
| Color Info | The image is a composite of separate exposures made by Hubble Space Telescope ACS and WFPC2 detectors and the Chandra ACIS detector. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Pink (ordinary matter/hot gas): X-ray Blue (dark matter map): F450W (B) Yellow/cyan: F555W (V), + F814W (I) |
