   Explanation: [5]The rugged lunar south polar region lies at the top of
   this colorful portrait of a last quarter Moon made on August 20.
   Constructed from video frames and still images taken at Springrange,
   New South Wales, Australia it also [6]captures a transit of China's
   [7]Tiangong Space Station. The transit itself was fleeting, taking the
   space station less than a second to cross the shadowed and sunlit lunar
   disk. The low Earth orbiting Tiangong is at an altitude of about 400
   kilometers, while the Moon is some [8]400,000 kilometers away. Subtle
   color differences along the bright lunar surface are revealed in the
   multiple stacked frames. [9]Not visible to the eye, they indicate real
   differences in chemical makeup across the lunar surface.
