This 31 July, the world is a phenomenon not seen since August 2012, are talking about the ‘Blue Moon’.
According to the magazine ‘ Astronomy ‘, the’ Blue Moon ‘occurs because the lunar cycle and timing are not well synchronized. If the month is always a full moon, every three years, ends with two full moons in the same month to well adjust the lunar cycle.
So this July 31 will be the second of the month, so called ‘Blue Moon’.
If the call blue is the presence of particles of smog or dust in the atmosphere.
In 1883, an Indonesian volcano Krakatoa erupted and threw so much ash into the atmosphere that moon made a bluish hue for several years.
