The Pale Blue Dot

Explanation: On Valentine's Day in 1990, cruising four billion miles from the Sun, the Voyager 1 spacecraft looked back one last time to make the first ever Solar System family portrait . The portrait consists of the Sun and six planets in a 60 frame mosaic made from a vantage point 32 degrees above the ecliptic plane. Planet Earth was captured within a single pixel in this single frame. It's the pale blue dot within the sunbeam just right of center in this reprocessed version of the now famous view from Voyager . Astronomer Carl Sagan originated the idea of using Voyager's camera to look back toward home from a distant perspective. Thirty years later, on this Valentine's day, look again at the pale blue dot .
