Surely everybody has heard the expression “once in a blue moon” at least once in their lives and so, everybody knows that it refers to something very special and something very rare, that only comes along once in a long period of time.
Well, astrologists are letting us know that next week we will be witnessing something very special, a very rare natural phenomenon that is worth acknowledging. On Friday, July 31st we will be having a Blue Moon and it’s going to be an amazing sight.
If you’re expecting the moon to actually be blue in color, that we are sorry to disappoint you, but that is linked to an entirely different type of natural occurrence. The moon becomes visible as blue only after volcanic eruptions of significant proportions take place and cause a special type of chemical plume to rise in the atmosphere. The chemicals are the ones that make the the moon appear blue from Earth.
The moon from Friday night will look like a regular full moon, but what will be truly special about it is the fact that it is the second one that we are getting this month. This is one of the instances that the astrological term blue moon refers to.
Considering that a lunar cycle is 29.53 days, July 2015 is bringing two full moons instead of the regular one per month that we usually get. The last full moon that we got this month was on July 2nd and next week will be blue moon. This means that we will be having 13 full moons this year, instead of the regular 12 and also 4 full moons this season instead of the regular three.
This phenomenon occurs only once every few years because it originates from the difference in the duration of the solar year and 12 lunar cycles. The difference adds up every month and once every 3 or 4 years, we get blue moons.
While astronomers will marvel at this celestial celebration, romantics get a chance to be hopeful and optimistic, because they do say that anything could happen on a blue moon. So save a few minutes on Friday night to remember that it is one to be remembered and be optimistic, because it just might be the night of your life!
