Lunar Eclipse in Two Hemispheres

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.

两个半球的月食现象

说明: 这两组引人注目的缩时摄影系列追踪了九月的月全食，它们横跨地球南北半球的夜空。在北半球的序列中（上图），月亮的轨迹从左上方弧形移动到右下方。它从明亮的土星下方经过，这一景象来自位于北纬30度左右的中国浙江大学国际校区的晴朗天空。相比之下，从南纬35度的澳洲坎培拉格里芬湖看到的南半球景色则记录了月亮从右上方延伸至左下方的轨迹。地平线附近雷暴产生的多道闪电倒映在湖中。这两个序列均使用16毫米广角镜头拍摄，并涵盖整个月食，暗红色的月亮完全浸没在地球中心附近的本影中。然而，月亮在天空中运行路径的不同方向显示了北纬和南纬观测造成的视角变化。
