Looking at the moon in #742 it has a very unusual crescent shape. Normally, a crescent moon's dark side would go from pole to pole, because the light from the sun will always illuminate exactly half the moon at any one time, and the position of the moon relative to the sun and the planet will determine how much of the dark half is visible from the planet. In this strip, much more than half of the moon would have to be illuminated UNLESS we are actually seeing the full moon - the entire lit half is facing the planet - and another body is passing between sun and planet and casting a shadow.

I contend that there are only two possible explanations for the shape: either it is artistic choice, or there is an eclipse.

So, IF there is an eclipse, does this MEAN something?
