As expected, the super full moon that rose on the night of August 30-31 — bigger and brighter than usual, given its proximity to Earth: only 222,043 miles (357,344 kilometers) or so — surprised and delighted stargazers from around the world. The phenomenon is defined by experts as “Blue Moon”, with reference to the frequency with which it occurs (full moon twice in a month), and is not linked to the actual color of the Earth’s satellite planet. The origin of the term is linked to the English language, where the expression “once in a blue moon” (“once in a blue moon”) indicates a rare and unusual event.
