Color: |
The image is a composite of separate exposures made by the WFPC2, ACS, and WFC3 instruments on the Hubble Space Telescope. Three filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
F814W (I) |
red-yellow |
F658N (H-alpha + [N II]) |
red |
F555W (V) |
blue-cyan |
