Release Date: January 5, 2010
Color: The image is a composite of separate exposures made by the WFC3 and ACS instruments on the Hubble Space Telescope. In total, 10 filters were used to sample a very wide wavelength range. The color results from assigning different hues (colors) to combinations of the monochromatic images. In this case, the assigned colors are:
WFC3/IR F125W+F160W red
ACS/WFC F606W+F775W+F850LP
WFC3/IR F098M
green
WFC3/UVIS F225W+F275W+F336W
ACS/WFC F435W
