Hey..I'm back!!
Actually it's kinda late to post
this (sorry :),
but, I do feel the urge post this
sooner or later.
So here we go~
Just a little information that last
August was my birthday (I won't tell you the date tho)
-I know it's not important-
Aaand...it was also the month when one unique phenomenon occured
-At that time,I don't even know it really existed-
-At that time,I don't even know it really existed-
So, can you guess?
YEP,
It's the Blue Moon.
huh.?
Okay, so here goes the scientific information :
A blue moon is an additional full moon that appears in a subdivision of a year: either the third of four full moons in a season, or a second full moon in a month of the common calendar.
A blue moon is an additional full moon that appears in a subdivision of a year: either the third of four full moons in a season, or a second full moon in a month of the common calendar.
The phrase has nothing to do with the actual colour of the moon, although a literal "blue moon" (the moon appearing with a tinge of blue) may occur in certain atmospheric conditions: e.g., when there are volcanic eruptions or when exceptionally large fires leave particles in the atmosphere.
The most literal meaning of blue moon is when the moon (not necessarily a full moon) appears to a casual observer to be unusually bluish, which is a rare event. The effect can be caused by smoke or dust particles in the atmosphere, as has happened after forest fires in Sweden and Canada in 1950 and 1951, and after the eruption of Krakatoa in 1883, which caused the moon to appear blue for nearly two years. Other less potent volcanoes have also turned the moon blue. People saw blue moons in 1983 after the eruption of the El Chichón volcano in Mexico, and there are reports of blue moons caused by Mount St. Helens in 1980 and Mount Pinatubo in 1991. In the Antarctic diary of Robert Falcon Scott for July 11, 1911 his entry says, "... the air thick with snow, and the moon a vague blue". On that date the moon phase would have looked full.
On September 23, 1950, several muskeg fires that had been smoldering for several years in Alberta, Canada, suddenly blew up into major—and very smoky—fires. Winds carried the smoke eastward and southward with unusual speed, and the conditions of the fire produced large quantities of oily droplets of just the right size (about 1 micrometre in diameter) to scatter red and yellow light. Wherever the smoke cleared enough so that the sun was visible, it was lavender or blue. Ontario, Canada, and much of the east coast of the United States were affected by the following day, and two days later, observers in Britain reported an indigo sun in smoke-dimmed skies, followed by an equally blue moon that evening.
The key to a blue moon is having lots of particles slightly wider than the wavelength of red light (0.7 micrometer)—and no other sizes present. It is rare, but volcanoes sometimes produce such clouds, as do forest fires. Ash and dust clouds thrown into the atmosphere by fires and storms usually contain a mixture of particles with a wide range of sizes, with most smaller than 1 micrometer, and they tend to scatter blue light.
Oh WOW, so the Blue Moon does really exist and that's a natual phenomenon.

I remember the first time I read the news about The Blue Moon,my thought was like "what? such a nonsense....seriously, they've got to be joking".
Uh well, they're not joking ...
It was real.(dumbfounded)
And Yeah, I'm feeling satisfied that I've finally wrote this,
Big Thanks to you all my readers, hope this could inspire you.
Wait for my another, yet to come articles OK..? :D
"Sayonara"~
