Once in a Blue Moon...

Tomorrow night, May 31st- the western hemisphere will experience a Blue Moon. Check out this article *here* for some interesting facts describing what a blue moon is, and how the name was coined.

Interesting quote from the article:

If you told a person in Shakespeare's day that something happens "once in a Blue Moon" they would attach no astronomical meaning to the statement. Blue moon simply meant rare or absurd, like making a date for "the Twelfth of Never."

But "meaning is a slippery substance," writes Philip Hiscock of the Dept. of Folklore, Memorial University of Newfoundland. "The phrase 'Blue Moon' has been around a long time, well over 400 years, and during that time its meaning has shifted."

Tomorrow night would be an opportunity to make a memory with your kids, according to this NASA article, the next Blue Moon will not happen until December 31, 2009.
