Color:

The image is a composite of several separate exposures made by the ACS instrument on the Hubble Space Telescope . Two filters were used to sample broad wavelength ranges in the yellow and near infrafed. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F435W ( B )

blue

B + r

green

F625W ( SDSS r )

red
