Flyby of Jupiter  

Voyager 1 began photographing Jupiter in January 1979. Its closest approach came on 5 March 1979, passing approximately 349,000 kilometers (217,000 miles) from the planet’s center, before completing its survey of the Jovian system in April. Among its most significant discoveries were active volcanoes on Io—the first such volcanic activity ever observed on another body in the Solar System.

Flyby of Saturn  

Voyager 1 reached Saturn in November 1980, making its closest approach on 12 November, when it passed within 124,000 kilometers (77,000 miles) of the planet’s cloud tops. Its cameras revealed intricate structures within Saturn’s rings, while its scientific instruments conducted detailed studies of the atmospheres of Saturn and its largest moon, Titan, long of interest for its dense—if inhospitable—atmosphere. Voyager 1 also recorded wind speeds on Saturn of up to 500 m/s (1,100 mph) and measured the planet’s rotation period at 10 hours, 39 minutes, and 24 seconds.

These two chromogenic prints are composite images consisting of each planet and moon, photographed separately and then assembled into accurately-scaled images.
