银河说-每日一图171204期：地月同框
本期为视频，视频见：https://galaxsay.com/2017/12/05/earth-and-moon/地月同框说明：在极少数情况下，地球和月球会被拍入同一个画面。上一次出现这种奇观是在25年前的12月，当时正巧伽利略号木星探测器经过地球，在15倍地月距离之外拍到了月球这颗地球唯一的天然卫星从地球前方滑过时的图片。将由此得来的52张具有历史意义的图片增强对比度，再连缀起来，就有了上方的影像。影像中，月球在地球旁边显得有些娇小，但是太阳系中，没有第二颗行星能与其卫星大小如此相当。在右方远处的太阳的照射下，地球和月球各有半边亮着，地球上亮着的半边可见回旋打转的白云、蔚蓝的海洋和暗色的陆地。而25年后的今晚，也就是在日落之后到明天日出之前，一个超级月亮即将现身。这次的超级月亮是满月，也就是橡树之月。（译注：在西方文化中，橡树有着强大、长生等的寓意，12月的满月被称作橡树之月，寓意新生。）译：银河说翻译组 飞果Earth and Moon

Explanation: On rare occasions, the Earth and Moon are photographed together. One of most spectacular times this occurred was 25 years ago this month 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. Tonight, a nearly full Oak supermoon will be visible from all of Earth from sunset to sunrise.
