When it comes to celestial events, a blue moon is relatively rare. In fact, the moon only appears blue about once every three years. So, why do they call it a blue moon?
The answer is actually quite simple. The moon only appears blue when there is a particularly high concentration of dust or smoke particles in the atmosphere. This is because these particles scatter sunlight in all directions, including back towards the moon. And when the moon is bathed in this blue light, it takes on a stunning blue hue.
So, next time you see a blue moon, you’ll know that it’s not just a coincidence or a rarity, but rather a result of the atmospheric conditions on Earth.
A blue moon is the name given to the second full moon in a month. It typically occurs every 2.7 years. The name is thought to have originated in the 1930s with the publication of the Maine Farmers’ Almanac.
The moon doesn’t actually turn blue, but every once in a while we get a “blue moon.” The term has become synonymous with rarity. So, why do we call it a blue moon?
The answer is both simple and complicated. The simple answer is that it’s just a mistake. The complicated answer is that it’s a mistake that’s been repeated so often it’s become part of our folklore.
