Comment The Moon never looks the same twice (Score 1) 95
We're generally taught that the same face of the Moon always faces toward Earth, but that's only an approximation. There are a few effects that change the appearance of the Moon, so it'd be interesting to see how the AI reacts to those.
Obviously the phase affects how the Moon looks. Another is called "libration", due to the fact that the Moon's orbital speed varies, while it's rotational speed remains fairly constant. And the fact that the Moon's orbit is inclined 5deg. Parallax is the fact that two observers on the Earth, far appart, will see slightly different faces. The apparent size of the Moon changes as it gets closer and further away during its orbit. For a given phase, the actual ange of the Sun will vary exactly which portions of the Moon are lit.
With so many variables, the same moon nevere really repeats, so just using a stock Moon photo would produce a Moon which appears slightly different. So it'd be interesting ro see how the AI performs taking those into account.
