About The Image
Color InfoThis image is a composite of separate exposures acquired by the WFC3 and ACS instruments on HST. Several filters were used to sample broad 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:Wide M31 Image (at top)Blue: F336W(U)Cyan: F475W (g)Yellow: F814W(I)Red: F160W (H) (H) Detail M31 Image (at bottom)Light purple: F275W (UV)Blue: F336W (U)ACS/WFC: F475W (g)Dark red: F814W (I)
