A Rare Blue Moon Will Light Up the Night Sky On October 31 This Year!
Looks like we are in for an “once in a blue moon” experience this Halloween!
According to NASA, blue moons, which aren’t actually blue in color, usually only take place once every two and a half to three years. What makes this blue moon even more special is that it lands directly on Halloween. A full moon only falls on Halloween once every 19 years, according to The Old Farmer’s Almanac. If you happen to miss Halloween’s blue moon, there is a next seasonal blue moon expected to take place on August 22, 2021.
The phenomenon can either occur when there are two full moons in a single calendar month (a monthly blue moon), or when it’s the third or fourth full moon in a single season (a seasonal blue moon).
