About The Image
Color Info	This image is a composite of separate exposures acquired by the ACS/WFC instrument. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors represent not only changes in different filters, but also the same filters taken on different exposure dates to highlight features that change over time.
