Detailed explanation-1: -Eric Wu needs to take pictures at the border between the light and the dark part of the Moon.
Detailed explanation-2: -The Moon doesn’t emit (give off) light itself, the ‘moonlight’ we see is actually the Sun’s light reflected off the lunar surface. So, as the Moon orbits the Earth, the Sun lights up different parts of it, making it seem as if the Moon is changing shape. In actual fact, it’s just our view of it that’s altering…
Detailed explanation-3: -This is due to the low Moon’s light passing through more of Earth’s atmosphere than the high Moon’s light. That squashed look is due to Earth’s atmosphere behaving like a weak lens with moonlight being bent more near the horizon than it is slightly higher above the horizon.
