Example Input: NASA has given the people of Earth a rare treat: A color mosaic that captures not only Saturn, but also the tiny dots of Earth and other planets in the background.

Earth appears as a bright blue dot to Saturn's lower right, just above Saturn's outer, halo-like E-ring. Venus is a dot to the upper left, with Mars appearing as a faint red dot above and to the left of Venus. This is the first image in which Saturn, its moons and rings, and Earth, Venus and Mars are all visible, NASA said. The image -- a panorama of 141 wide-angle pictures -- covers 404,880 miles across Saturn and its ring system.Image is Cassini's first showing Saturn, rings, moons, Earth, Venus and Mars at same timeThe collage is panorama of 141 wide-angle pictures taken July 19Image was possible that day because Saturn obstructed spacecraft's view of sun
