Blue moon shines around the world

Tonight’s blue moon may not be as rare as it sounds, but it’s still special — as is every glorious full moon, whichever color you use to describe it.

Actually, the term “blue moon” is something of a misnomer. There’s no reason for the full moon to be any bluer than usual (though it’s certainly possible for the moon to take on a blue tinge). Instead, it has to do with the extra occurrence of a full moon in a given calendar cycle.
