"A composite photo of the position and phases of the moon over 28 days, each photo taken at the same time each day at the same exact place. (photo by Giorgia Hofer Photography in 2017)"
I have to think about this one. How is the moon visible at the same time from the same location for an entire month? The moon moves from west to east 15 degrees each night. It should be a smooth arc from right to left, but only half the lunar cycle should be visible, right? The waxing crescent should be closest to the horizon on the right at sunset and the waning crescent should be closest to the horizon on the left at sunrise. But they can't both be seen at the same time from the same location 27 days apart, can they? The waxing crescent sets just after the sun, far right image if this is in the northern hemisphere. The 1st qtr moon is at apex at sunset. The full moon rises at sunset. The 3rd qtr moon is at apex at sunrise and the waning crescent rises just before dawn. That's not what this photo shows. This can't be a composite of photos taken at the same time from the same location on successive nights. But it's a pretty picture, and a fun puzzle to sort out
