Pluto – HST – 90° Longitude

About the colours

The image is a composite of separate exposures made by the ACS/HRC instrument on the Hubble Space Telescope. Two filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F435W (B) Green: F555W (V)
