The full moon of May is typically known as the moon of the flower because of all the blooms this month. This year coincides with a rare occurrence: a blue moon.
Of course, the moon on this Saturday will not really be blue. And the reason for the name is a bit confusing.
A blue moon is the second of two full moons in a month, but it can also be the third of four full moons in a single season. In this case, it is the third of four full moons this spring. These do not happen as often as two full moons in a month.
Gianluca Massey, an astrophysicist and director of the project of the telescope to the default in Rome, said in an email: “the name” Blue Moon “has nothing to do with the moon.” “Every two or three years we have 13 full moons a year. In this way, we can get four full moons during a certain season or two of full moons in a given month. “
Very rarely, both types of blue moons occur in a year; this will occur in 2048, including a monthly blue moon in January and a seasonal moon in August.
Sometimes, the moon may appear blue in certain conditions of the sky, but it can not be predicted.
Then, this Saturday, enjoy the view of the beautiful moon with some appreciation for its meaning.
