This Hubble image shows the galaxy cluster Abell 2813. The color image was compiled using observations taken with Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) instruments. Several filters were used to sample various optical wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
