Solar System Spotlight: Moon

When someone says “once in a blue moon”, you know they mean something that doesn’t happen often. In fact, blue moons happen about every two-and-a-half years, when there is a second full moon in one calendar month. This October, experience a rare event – a blue moon on Halloween! For the first time since 2001, the second full moon of the month will illuminate Halloween night.
