Spiral Galaxy NGC 7329 in Tucana | Hubble Space Telescope
How are colorful Hubble images possible given that raw Hubble images are monochromatic? This is accomplished by combining multiple observations of the same object obtained using a choice of filters. This image, for example, was processed from Hubble observations made using four filters, each of spanning a distinct region of the light spectrum—from the ultraviolet to optical and infrared. Specialized image processors and artists can make informed judgements about the optical colors that best correspond to each filter used. They can then color the images taken using that filter accordingly. Finally, the images taken with each filter are stacked together, and voila! The colorful image of a distant galaxy is complete with colors as representative of reality as possible.
