Blue Moon phenomenon on New Year's Eve 2010

Blue Moon - an interesting phenomenon, will appear again on New Year's Eve to the new year 2010 after the last time 10 years ago.

By the definition of Westerners, Blue Moon is the second full moon night in a calendar month , a phenomenon with an average frequency of about 2 and a half years.

In December 2009, there will be two full moon on the 2nd and 31st days. The Blue Moon appears correctly on the New Year's Eve is a rare event.

The most recent occurrence of the Blue Moon on New Year's Eve is in 1990 and astronaut David Reneke works for the Ocean Science Journal to predict that this overlap will only repeat in 2028.

The second full moon phenomenon in the solar month is no different from any other full moon , however, the moon can change color under certain conditions.

For example, wildfires or volcanic eruptions often make the atmosphere thick with ash, causing the Moon to look bluish, even purple. The volcanic eruption of Krakatoa in Indonesia in 1883 caused Earth's atmosphere to be soaked with ash so that the Moon was bluish until two years later.

According to Astronaut David Reneke, this year, the Moon will not turn green and may turn red when viewed from cities due to the effects of fireworks smoke. Therefore, the best way to enjoy the Blue Moon is for the viewer to stay away from the city lights.

No one knows exactly where the concept of 'Blue Moon' comes from and when it appeared. However, in the West, the phrase Blue Moon has become a metaphor for a rare event.

The term appeared in an English book in 1518 that criticized the clergy of the time, meaning that "if you see the Moon is green, you must believe that it is true."

Another interpretation of the phrase suggests that it is derived from an ancient English word meaning "color" or "traitor" because clergy call the phenomenon of the Moon early when Easter week for Easter is 'Moon betrayed' or 'Moon in color'.
