This composite of planetary images was taken by various NASA spacecraft. Included are (from top to bottom) Jupiter, Saturn, Uranus, and Neptune. Jupiter was imaged by Cassini. The Saturn, Uranus, and Neptune images were captured by Voyager. NASA / JPL




The four largest moons of Jupiter are collectively called the Galilean satellites, named after Galileo Galilei who discovered them in 1610. In terms of size, Ganymede (far left) is the largest, followed by Callisto, Io, and Europa. In terms of distance, Io is the closet, followed by Europa, Ganymede, and Callisto. NASA / JPL

This 15-minute, unguided exposure was captured onto Kodak Elitechrome 200 slide film by a Minolta SRT101 camera with a 16mm lens at f/2.8 mounted on battery-driven, motorized camera mount. The image was digitized using a CanoscanFS2710 and auto-contrast adjusted using Photoshop6 to bring the image back as close as possible to the original. Russell Cockman
