Explanation: The Earth and Moon are rarely photographed together. One of most spectacular times this occurred was about 30 years ago when the Jupiter-bound Galileo spacecraft zoomed past our home planetary system. Then, robotic Galileo watched from about 15-times the Earth-Moon separation as our only natural satellite glided past our home world. The featured video combines 52 historic color-enhanced images. Although our Moon may appear small next to the Earth, no other planet in our Solar System has a satellite so comparable in size . The Sun, far off to the right, illuminated about half of each sphere, and shows the spinning Earth’s white clouds, blue oceans, and tan continents.

说明: 地球和月球鲜少同时入镜。这种蔚为奇观的实例之一,就出现在30年前的这个月,时值前往木星的伽利略号太空船掠过我们所在的行星系统。在当时,无人的伽利略号从15倍地球─月球间距之外远眺,看见地球唯一的天然卫星滑过地球前方。在这部结合了52张历史性色彩强化照片的主题影片里,虽然在地球旁边的月球看来有些娇小,但是在我们太阳系里,没有其他的行星拥有大小如此接近的卫星。拍照时,太阳位在右方的远处,照亮这二个球形天体的半边,让我们得以见到回旋的白云、蔚蓝的海洋和暗色的大陆块。
