Cassini's narrow-angle camera took these four images over a period of 20 minutes on April 3, 2004, when the spacecraft was 27.7 million miles (44.5 million kilometers) from the planet. In the upper left image, Saturn is seen in ultraviolet wavelengths (298 nanometers); at upper right, in visible blue wavelengths (440nm); at lower left, in far red wavelengths just beyond the visible-light spectrum (727nm); and at lower right, in near-infrared wavelengths (930nm).
