   Explanation: September's total lunar eclipse is tracked across night
   skies from both the northern and southern hemispheres of planet Earth
   in these two dramatic timelapse series. In the northern hemisphere
   sequence (top panel) the Moon’s trail arcs from the upper left to the
   lower right. It passes below bright planet Saturn, seen under mostly
   clear skies from the international campus of Zhejiang University in
   China at about 30 degrees north latitude. In contrast, the southern
   hemisphere view from Lake Griffin, Canberra, Australia at 35 degrees
   south latitude, records the Moon’s trail from the upper right to the
   lower left. Multiple lightning flashes from thunderstorms near the
   horizon appear reflected in the lake. Both sequences were photographed
   with 16mm wide-angle lenses and both cover the entire eclipse, with the
   darkened red Moon totally immersed in Earth's umbral shadow near
   center. But the different orientations of the Moon’s path across the
   sky reveal the perspective shifts caused by the views from northern vs.
   southern latitudes.
