Blue Supermoon: On Monday, 19th August, the festival of Raksha Bandhan will be celebrated in the country, on this day a big astronomical event is reported to happen. On this day in the evening, the biggest and brightest moon, which is also being called Super Blue Moon, will appear in the sky. This is no ordinary full moon. It is a supermoon, a blue moon and many other names and cultural significance are associated with it which make it an amazing astronomical event.
First of all, let us know why this is a supermoon? This term was first used by astrologer Richard Nolle in 1979 to describe a new or full moon, which occurs when the moon is closest to the Earth i.e. 90 percent close. It also has a strange name which is also called Sturgeon Moon.
Blue Moon is an astronomical phenomenon
This is an astronomical phenomenon that occurs when there are two full moons in the same month or four full moons in a season. The third full moon is called a Blue Moon. When the moon is closest to the Earth, it is called a Supermoon. In this situation, the moon appears 14 percent larger and 30 percent brighter than a normal full moon.
Will the moon really appear blue?
The history of the term blue moon stretches back to 1528 and its origins are somewhat mysterious. Some believe it comes from an old English phrase meaning “treacherous moon,” while others believe it may refer to the rare times when dust in the atmosphere gives the moon a blue hue.
In recent times, the term is also used to describe the second full moon in a month that has two full moons. In this event, the moon is not blue in colour. It is in its natural colour but on this day the moon appears larger and brighter. Usually, a blue moon occurs once every 2-3 years.
