Blue Moon

What Is a Blue Moon?

"Blue Moon" is a truly rare phenomenon that involves the presence of a full moon in a given time. What, though, is that period? It turns out that there are two meanings of the word, and one was the result of a misunderstanding of the other.

More stringent significance marks Blue Moon as the third full moon at four full moons. Named Blue Moon from time to time, this occurs about 2.5 years each, as indicated by NASA Extremely fast, the term Blue Moon was used in the next full moon during the month of the schedule alone. There are usually 29.5 days between full months, which makes it rare for two full months to enter a 30 or 31 day tax-paying month. (This means that February will never have Blue Moon.)

Which is right? All things considered, because the language and meaning of the words continue - select. Both are widely used today and any definition is considered great. As Texas astronomer Donald W. Olson wrote in a 2006 article in Sky and Telescope magazine, "With twenty years of known use behind it, the second full-moon-mis (mis) definition is like a genius." But that is not a bad thing at all. "

Next month to the month Blue Moon will be October 31, 2020, as indicated by NASA. The keep going one was March 31, 2018. The third full month of that period will be May 18, 2019.

Inception of the term

The term "rare" has been around for more than 400 years, as shown by Philip Hiscock, a mythologist at Memorial University of Newfoundland. In a 2012 article in Sky and Telescope magazine, he pointed out that the use of a quick term was like explaining that the moon is made of green cheddar - it showed something crazy. "He would argue that the moon is blue" was like saying, "You would argue that that black is white."

Improved value of something like "never," according to Hiscock. "I will marry you when the moon turns blue" turned into something that can be compared to "I will marry you when hell is over."

"Most of the Blue Moons look very dark and white, it is not clear if you have ever seen one," as NASA points out.

never say never. Significantly, the moon may appear blue, as it did in 1883 after the spring of the Krakatoa lava eruption. The fossils that were seen all around went as a channel, making the evening and the moon green and blue all over the world, an event NASA said was thought to have unveiled the phrase "blue moon." Sometimes, for example, wood flames and residual storms can turn the moon blue.

In line with these lines, the value of "rare" changes from "never" to "rare," as Hiscock pointed out.

When does a Blue Moon happen?

At the moment we come to the books against the definitions of Blue Moon.

The temporal meaning of the word Blue Moon is followed by the August 1937 edition of the Maine Farmer Almanac, which stated that the moon "as a rule comes in full several times a year, several times per season. , not the 12th standard. Moreover, that equally full moon would suggest that one of the four seasons would have four full months instead of the usual three. "

 For example, the last full moon of winter needed to fall during Lent; it was known as Lent Moon. The full moon of spring is known as the Egg Moon - or Easter Moon, or Paschal Moon - and had to enter within the last week of Easter. So when a particular period was four months, the third was named Blue Moon, with the intention that other full moons could occur at better times compared to solstices and equinox.

However, should not something be said about the meaning that many people have heard - that Blue Moon is the second full moon in a single month? That came as a shock to the original definition in 1946, which was used as a hot spot for a widely divided radio program in 1980.
