When something is rare, it only happens 'Once in a Blue Moon.' Well, the blue moon happens tonight! What is a blue moon? It is defined as a second full moon during a calendar month. While most years have 12 full moons, this year has 13. Blue moons are very rarely blue. In fact NASA experts say tonight's blue moon could actually appear red depending on where you are.

The last blue moon was on August 31st of 2012 and then next one won't happen until 2018! So go out and catch a glimpse of a blue moon tonight and do something daring or dangerous. You have permission.
