Blue Moon

Did you get to see the Blue moon this weekend? This guy lit up the sky this past Friday night. Well, it doesn't look blue you say? That's because blue moons aren't necessarily blue. A blue moon means that it is the 3rd blue moon in a season, whereas there are normally only 2. Blue moons happen roughly every 2.7 years, so if you missed this year's, you will have to wait almost three years for the next. There will be two full moons in a single month in July 2015 (July 1 and 31).
