On another Valentine’s Day 25 years ago, cruising four billion miles from the Sun, the Voyager 1 spacecraft looked back one last time to make this first ever Solar System family portrait. The complete portrait is a 60 frame mosaic made from a vantage point 32 degrees above the ecliptic plane. In it, Voyager’s wide angle camera frames sweep through the inner Solar System at the left, linking up with gas giant Neptune, the Solar System’s outermost planet, at the far right. Positions for Venus, Earth, Jupiter, Saturn, Uranus, and Neptune are indicated by letters, while the Sun is the bright spot near the center of the circle of frames. The inset frames for each of the planets are from Voyager’s narrow field camera. Unseen in the portrait are Mercury, too close to the Sun to be detected, and Mars, unfortunately hidden by sunlight scattered in the camera’s optical system. Closer to the Sun than Neptune at the time, small, faint Pluto’s position was not covered.

二十五年前的情人節，探測器Voyager 1在距離太陽四億英里的地方，回頭最後一次拍攝了這幅史上首張太陽系合照。這幅完整的肖像是由60幅畫面拼接而成，拍攝角度位於黃道平面上方32度的位置。在這幅合照中，Voyager的廣角相機從左邊捕捉到內太陽系的行星，並在最右側連接上太陽系的最外層行星——氣體巨星海王星。畫面中，金星、地球、木星、土星、天王星和海王星的位置分別用字母標註，而太陽則是圓形畫面中央明亮的一點。每顆行星的插圖是由Voyager的窄角相機拍攝的。畫中未能顯現的有水星，因為它太靠近太陽而無法被侦测到，而火星則因為相機光學系統中散射的陽光而被遮住。當時位於海王星內部的小而微弱的冥王星，由於位置不包括在此次拍攝中。
