What is a blue moon and why should you see the one on March 31?

Evoke poetry in the name of Moon it is something that has been done practically since men have dedicated themselves to looking at the sky. The blue moon has not been the exception.

The name of this powerful cosmic phenomenon is nothing more than poetry and meaning. A blue Moon (by his name in English, blue moon) is a full moon: the second occurred in the same month of the Gregorian calendar. Previously, the third of four full moons that occurred in a season of the year was also called that (according to various studies, it occurs every 2.5 years). Both perspectives are correct to define if a full moon is also blue.

From this last reference a very beautiful meaning emerges, that of color blue. No one could think that the color blue, in its English form, blue, was named for this unique full moon. But, in fact, there is a version that says that it was so. The blue moon is actually a nice play on words that comes from Old English, from the expression belewe, which means «traitor». This term was synthesized in blweand due to its pronunciation, in blue. So this moon was designated as a «treacherous moon», because it made the fast of Lent prolonged.

So one blue moon A blue moon is an extra full moon that occurs due to a quirk of the calendar. The next blue moon (a second full moon that will appear only in a month) will be this Saturday March 31, 2018. The last one was magnificent super blue blood moon, which left many shocked on January 31. After this blue moon, we won’t see another one again until spring 2019.

According to NASA references: «Most blue moons are pale gray and white in color, indistinguishable from any other moon you’ve ever seen.» But this quality is not incorruptible, as the Moon has already been bluish once, in 1883, due to the eruption of the Krakatoa volcano in Indonesia. On that occasion the dust in the air acted as a filter, causing sunsets, and the Moon turned green and blue all over the world. Other events, like forest fires, can also cause the moon to appear blue.

The blue moon may be a full moon like any other, but no one can deny that its unpredictable appearance, always in a different time and space, is unique.

This coming Saturday, dedicate a few moments to this emblematic blue moon, and enjoy the benefits that nature shares.
