The Blue Moon arrives on time on Halloween night: nothing to do with the color of our satellite, which remains the same as always, but is called the second full Moon that occurs in a month.
Brilliant and spectacular, it will be bright in the sky, clouds permitting.
“On average we have a full Moon per month as our satellite takes 29.5 days to complete its cycle, which is just under a month.
For this reason it happens that, from time to time, we have 13 times the full moon in a year ”, explains astrophysicist Gianluca Masi, head of the Virtual Telescope.
"Sometimes - he continues - it happens that the blue moon is the second full moon in a month, in other cases it is the fourth of a season". And this is where the name "Blue Moon" comes in: for some it is the second full moon of a given month, for others the third full moon of a season that has four. As for this October 2020, the Blue Moon is the second of the month. His images of Rome and its monuments are broadcast live on the web at 5.30 pm by the Virtual Telescope.
