Explanation:
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
captures a transit
of China's
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
400,000 kilometers away.
Subtle color differences along the bright lunar surface are revealed in
the multiple stacked frames.
Not visible to the eye,
they indicate real differences in chemical makeup
across the lunar surface.
