NGC 3972

About the colours

These images are a composite of separate exposures acquired by the WFC3/UVIS/IR instrument on the Hubble Space Telescope. Several filters were used to sample narrow wavelength ranges. 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: Luminosity: F350LP Blue: F555W Green: F814W Red: F160W
