It's a blue moon tonight! (Technically at 9:58 tomorrow morning, but it counts.) If you're like me a few years ago, you'd be looking for the moon to have a blue color to it.
"In fact, 'blue moon' refers not to color, but to rarity. Blue moons are defined as either the fourth full moon in a season, or, more recently, as the second full moon in a month. It's the second definition that covers August's blue moon; the month's first full moon was on Aug. 1.
"Blue moons happen because our calendar months don't precisely sync with the moon's orbit. It takes the moon 29.5 days to wax and wane from full to new to full again. With the exception of February, months are longer than that, meaning that once in a while the timing works out so there are two full moons in one month." msnbc.msn.com
If you miss this one, the next chance you get will be in 2015
