The Hubble data are taken from the HST proposal 11498: A. Simon-Miller (NASA Goddard Space Flight Center), N. Chanover (New Mexico State University), and G. Orton (Jet Propulsion Laboratory).
410 nm, 502 nm, and 673 nm
These images are a composite of separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Three filters were used to sample various wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
Blue: F410 M
Green: F502 N
Red: F673 N
