Whenever he thought about it, he felt terrible. And so, at last, he came to a fateful decision. He decided not to think about it. ~John-Roger and Peter McWilliams

Q:

Dear 100 Hour Board,

Is the moon visible to all places on the globe every night (except during new moons and certain weather, of course)?

- Crater Watcher

A: Dear Watcher,

Yes, it is. There are some interesting timing issues due to phase cycle of the moon, though. For instance, there are days where the moon never rises or sets, because the moon's phase cycle is 29.5 days, while the average calendar cycle is 30.4 days. (For more info, see this article.)
