All my life I've thought a blue moon was some super rare event in which the moon actually appeared blue. You know, like the saying, "once in a blue moon." A harvest moon is always gold, so I thought why not a blue one?
I heard on the news that tonight is a blue moon. I've been looking out there all evening and, while the moon is full, I was curious as to when it would start to look blue.
So I googled it. Turns out, it's not blue.
