Release Date: August 16, 2012
Color: The images are composites of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Five filters were used to sample broad and narrow wavelength ranges for the UVIS image. The colors result from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
WFC3/UVIS image of 30 Dor
F336W (U) and F438W (B) blue
F555W (V) green
F814W (I) red
F656N (H-alpha) orange/red
Orientation: Compass and Scale Image of Merging Star Clusters in 30 Doradus
