说明: 这是行星间的第一次在同一天，从内外太阳系两侧，水星和土星为地球拍照。左边照片是由正在环绕气体巨行星─土星的卡西尼太空船拍的，土星环下的蓝白色小点是地球；右边照片是由正在环绕水星的信使号太空船拍的，地月系统在黑色背景的衬托下特别显眼。在这张信使号拍的照片里，反射太阳光的地球(左边亮点)和月球(右边亮点)明亮地发光着。上週五信使号拍的这张长曝光的照片，其目的有一部份是为了探查这颗太阳系最里面且黯淡的天然卫星─月球。同一天，地球上的人类也为他们自己拍下土星的照片。

Explanation: In a cross-Solar System interplanetary first, our Earth was photographed during the same day from both Mercury and Saturn.Pictured on the left, Earth is the pale blue dot just below the rings of Saturn, as captured by the robotic Cassini spacecraft now orbiting the gas giant.Pictured on the right, the Earth-Moon system is seen against a dark background, as captured by the robotic MESSENGER spacecraft now orbiting Mercury.In the MESSENGER image, the Earth (left) and Moon (right) shine brightly with reflected sunlight.MESSENGER took the overexposed image last Friday as part of a search for small natural satellites of the innermost planet, moons that would be expected to be quite dim.During this same day, humans across planet Earth snapped many of their own pictures of Saturn.
