COVER: Saturn and two of its moons,Tethys (above) and Dione (below), were photographed by Voyager 1 on November 3,1980, from 13 million kilometers (8 million miles). The shadow of Tethys is cast onto thecloudtops in the upper right corner of the image.
The pictures assembled in this publication are a part of the rich and varied harvest of informationreturned by Voyager 1 across nearly a billion miles of interplanetary space. These images are ofgreat beauty as well as great scientific interest, serving to remind us of the awesome and breathtakingdimensions of the solar system we inhabit. Voyager is providing intriguing new information whichshould help us to understand how the Earth—and possibly the universe—was formed. Already therehave been surprises and puzzles that paint a completely new picture of Saturn and its neighborhood,including the discovery of three new moons, startling information about Saturn’s rings, and observationof the unexpectedly complex structure of Saturn’s atmosphere and that of its largest moon, Titan.It will take years for scientists to assimilate completely the information which is cascading down fromVoyager. What more will this marvel of technology have to tell us before it departs the solar systemto travel endlessly among the stars?
