A miracle in the sky happened on 31 Dec 2009. The blue moon brightened up more on that night for the excitement of all the people. Though it is mentioned as blue moon the moon was not in blue color. According to the Indians, if the occurrence of the full moon is happened second time in a month, it is called as the Blue Moon. Actually in a year the full moon appears for 12 times but sometimes, it appears 13 times for every 2 to 3 years. This incident happened on December 2nd and again this took place on 31st of this month. All this information is passed on by the Science Popularization Association of Communication and Educators which is one of the important organizations for the special researches. In general, the moon appears blue in color when the sky is covered with a lot of dust and snow. But this process is totally different from this idea of getting the blue moon when it is covered by dust or snow. According to the special research center, it takes nearly 29.53 days to form a full moon which in terms can be called as one month. By this we can say that for every one month one full moon appears. But the moon which is left for the whole year forms as a second moon after 2 to 3 years which is called as the Blue Moon. After this formation of the blue moon on 31st again it happens on November 21, 2010 and August 21, 2010. So it is going to be a great experience for the people on 31st to watch this wonder which happens after many years.
