The night sky will bring additional pleasure to this Halloween.
The night sky will bring additional pleasure to this Halloween, because it has a spectacle that has not been for almost two decades.
This year, Halloween is shaped much differently by the coronavirus pandemic, when some communities decided to end the scam to reduce the risk of the virus spreading from one household to another. But in areas where young masquerades will go from door to door collecting candy, they will have a bright full moon that will help light the way.
It won̵7;t be a typical full moon either – it will be a blue moon.
Unlike the name, the blue moon does not look blue. It’s just a nickname given to the second full month in a calendar month. However, the moon can take on different colors, such as orange and red, when it is near the horizon, just as the sky can take on bright colors when the sun is near the horizon.
“The modern understanding of the Blue Moon began to develop only in the 1980s. It was the result of a much earlier mistake published in the 1946 issue of Sky & Telescope, and since then the term has become widespread in the media,” explained the old farmer’s Almanac.
The first full moon in October came on the first day of the month and was one of the most famous full months of the year: Harvest Month. Harvest Moon is the nickname of the full moon closest to the autumnal equinox, and usually shines in September, but 2020 was one of the cases when it appeared in early October.
According to NASA, blue satellites like this month occur about once every two and a half years. This irregularity was the phrase “once a blue moon.”
Those who are superstitious may want to carry the spell of good luck on October 31 and keep it on hand, Friday the 13th right around the corner in November.
Some advertise the blue moon on Halloween as a rare celestial event, forcing people to think about how rare this event is compared to the typical blue moon.
“On average, the month of Halloween is full every 19 years,” NASA said. “In fact, every full moon on Halloween is also a Blue Moon.”
The last full moon lit up the sky on Halloween night in 2001; however, clouds obscured the eerie spectacle for people in the northeast, the northern plain, and along Interstate Corridor 5 in the Northwest Pacific.
This year, scammers may have children of their own the next time Halloween falls on the blue moon in 2039.
Where cloudless conditions prevail, you can see much more in the sky than just the moon.
After dark, three bright planets will be visible, including Mars to the right of the moon and Jupiter and Saturn nearby in the southern sky.
Installing a telescope and a good overview of these planets can be an interesting night for families who do not plan to cheat or treat because of a pandemic this year, although no telescope is needed to view the trio of planets.
Even looking at the moon through a telescope or simple binoculars, you can find countless craters that penetrate the surface of the Earth’s natural satellite.
The second full moon in a calendar month is the most common definition of a blue moon, but there is another way for a full moon to claim this nickname.
Instead of looking at the number of full months per month, you can find the blue moon when you look at the number of full months per season. There will usually be three full months each year, but this is not always the case.
“If there are four full moons in the season instead, then the third full moon (not the fourth) of the season can be called the Blue Moon,” the Old Farmer’s Almanac said.
Like the blue moon calendar, seasonal blue satellites appear every few years, the next coming down on August 22, 2021.
Since there are two types of blue satellites, there may be a calendar blue moon and a seasonal blue moon in the same year, but it will be another 17 years before the astronomers see the double celestial feature.
