After the Blue Moon on Oct. 31, 2020, trick-or-treaters will need to wait until 2039 to see the next blue moon on Halloween.
This year, Halloween is going to be a little more spooky than usual since, on October 31, 2020, there is going to be a blue moon. This is a great event for all the moon lovers and also an amazing opportunity to buy a telescope in case you don't have one. As reported by The Sacramento Bee, this year is going to have 13 full moons, which is going to include 2 supermoons. Also, when there are two full moons in a month and during such an instance, the second moon is known as a 'Blue Moon'.
The Blue Moon is all set to make the appearance on Halloween, just a few days before the 2020 Presidential election. The first moon of 2020 already appeared on January 10 and it was known as the 'Full Wolf Moon'. The Farmer's Almanac reported that the name comes from the howling of the wolves during the cold winter nights outside of Native American villages.
This time there are two full moons in October, and now you know where the phrase also comes from, 'Once in a blue moon'. According to NASA, "Most blue moons look pale gray and white, indistinguishable from any other moon you've ever seen. Squeezing a second full moon into a calendar month doesn't change the physical properties of the moon itself, so the color remains the same."
Even though there is no biblical reference to a blue moon, there are lots of references to blood moons and other signs that explain why some people wonder about the significance of celestial events like this. According to some of the Biblical scholars, the color blue is said to represent important things like heaven, royalty, and riches, and it might also refer to the Holy Spirit and the truth.
The Biblical references to the color blue can be found in contexts such as Exodus 24:10 that says, "...and saw the God of Israel. Under his feet was something like a pavement made of lapis lazuli, as bright blue as the sky." Even though there is a lack of biblical reference to a blue moon, WDAF TV reports that its a very rare event and the next one that will happen on Halloween will be in 2039. A full moon on Halloween occurs only once in 19 years and if these events are calculated using Greenwich Mean Time, it translates approximately 3-4 times per century.
