Hubble 47 Tucanae in UV with White Dwarfs Marked

About the colours

This image is a composite of separate exposures acquired by the WFC3 instrument. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Cyan: F225W (UV) Yellow: F336W (U)
