Color: |
This image is a composite of separate exposures acquired by the WFC3 instrument on HST. 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:
F390W + F606W |
blue |
F814W |
green |
F098M + F125W + F132N + F160W |
red |
