Ring In The New Year With A Blue Moon!

This New Year's Eve, a Blue Moon will shine down on earth. What's a blue moon? According to the popular definition, it's the second full moon in a month. It won't really be the color blue, however. It is very rare - New Year's Eve blue moons only occur about every 19 years. The last one was in 1990!
