Tonight’s #BlueMoon is sure to be epic! 🌚 #DidYouKnow that the term “Blue Moon,” is actually just a generic name given to the second full moon to occur in a single calendar month AND that we’ve actually already had one blue moon this year? Tonight will mark the last time we’ll be able to see a blue moon for a while though, as the next one won't come until Halloween night in 2020. 🎃 . . . . . #POTD #photooftheday #picoftheday #photography #picoftheday #nasa #fullmoon #sapmoon #bluesapmoon #sky #night #themoreyouknow #funfacts #facts
