Galaxy Cluster MACS J1149.5+2223

About the colours

This image is a composite of separate exposures acquired by the ACS and WFC3 instruments on the Hubble Space Telescope. Several filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F606W+F814W Green: F105W+F125W Red: F140W+F160W
