Explanation: What’s that unusual spot on the Moon? It’s the International Space Station. Using precise timing, the Earth-orbiting space platform was photographed in front of a partially lit gibbous Moon last month. The featured composite, taken from Payson, Arizona, USA last month, was intricately composed by combining, in part, many 1/2000-second images from a video of the ISS crossing the Moon. A close inspection of this unusually crisp ISS silhouette will reveal the outlines of numerous solar panels and trusses. The bright crater Tycho is visible on the upper left, as well as comparatively rough, light colored terrain known as highlands, and relatively smooth, dark colored areas known as maria. On-line tools can tell you when the International Space Station will be visible from your area.

说明: 月亮上头的不寻常暗斑是什么？国际太空站是也。借助于精确的计时，摄影者在上个月补捉到地球轨道上的国际太空站，出现在半明半暗的凸月前方。这幅摄于美国亚利桑那州培森市的主题影像，是由数张以1/2000秒短曝光、记录国际太空站凌越月亮的影片定格精妙组合而成。如仔细检视异常清晰的国际太空站剪影，会发现它诸多的太阳能板和桁架之轮廓清楚可辨。此外在影像中，左上角有明亮的第谷坑，与及相对崎岖名为高地的淡色原野和相对平滑的暗色月海。运用一些线上的工具，可找出从你所在之地，于何时可见到国际太空站。
