In the night between 22 and 23 August there was the blue Moon: the full moon, brilliant, gave a show in the skies of the whole world accompanied by the two planets Jupiter and Saturn (in the photo, Milan)

Why is it called the blue moon

The definition of blue moon has nothing to do with the color of our satellite: it takes this name out of a curiosity related to the calendar, as it is the third full moon of a season that hosts four (in the photo, the moon in Brazil)

The blue moon is an unusual but not rare event, which recurs approximately every two and a half years: the next will be in 2024 (in the photo, the moon in Greece)

In the 1930s the Maine Farmers’ Almanac used the term “blue moon” to refer to the third full moon of a season that hosts four. This was the third full moon of summer 2021, which has already given us two full moons (June 24 and July 24) and will give us a fourth on September 21 (in the photo, the moon in Greece)
