Pale Blue Dot On the Cover: Voyager 1 turned its camera back on its home planet for the last time on February 14, 1990. For the first time, humankind could see itself in perspective from the edge of our solar system—something possible only through our efforts to explore other worlds. This evocative representation of Earth appeared in the book Pale Blue Dot by Carl Sagan. To see the image of Earth taken by Voyager 1, go to http://planetary.org/html/society/advisors/sagandot.html.
