Release Date: November 5, 2009
Color: The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Five 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:
F336W (U) blue
F555W (V) green
F814W (I) red
F502N ([O III]) cyan
F657N (H-alpha) red
