| About The Image | |
| Color Info | 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: Blue: Dark Matter Map + F438W (B) + VLT B Green: F606W (V) + VLT R Red: Chandra X-ray data + F814W(I) + VLT I |
