According to NASA, the last time a Blue Moon fell on New Year's Eve was almost 20 years ago, in December 1990. And although a Blue Moon occurs on average every two and a half years, the next time one will fall on New Year's Eve won't be until 2028.
In other words: Look up tonight if you can, and enjoy the extra moonlight! Will your New Year's Eve celebrations have a Blue Moon 2009 theme? Let us know in the comments.
