Let those who are white as usual next Saturday be assured: they will not be affected by color blindness.
A blue moon is not a color, but an astronomical phenomenon in which two full moons appear at exactly the same month., Jean David, President of the Wall-Belar Astronomy Corporation.
On the night of October 1, the first full moon shone. The second will appear on the 31st.
So 2020 will have this advantage: it offers 13 full moons more than the usual twelve.
Remember that blue moons occur every two and a half years NASANational Aeronautics and Space Administration. On the other hand, this phenomenon rarely appears at night in the heart.
The next time a blue moon rises on Halloween, it will be in 2039.
The Moon has been operating on a long-term basis in a 19-year cycle, explains Jean David. If we go back 19 years, we will see a full moon on October 31st in the same place.
What makes this year’s event extraordinary is that the entire planet will be able to celebrate this blue moon on October 31st.
The moon is always full for everyone, Jeanne underscores David, but it keeps moving. It takes 12 hours to move from one hemisphere to another; This means that she will get up early to fill up all over the planet on the same day.
It is said that the last time such a sight was seen around the world was in 1944 NASANational Aeronautics and Space Administration.
