Earth's Moon is the largest and brightest object suspended in the darkness of the starry night sky. It is both lovely and enchanting, and it has, since ancient times, inspired curiosity and wonder in human beings who gaze up at the mysterious sky after the Sun has set. As such, Earth's Moon has long served as the inspiration for imaginative, wild and marvelous tales--it is the stuff of mythology and folklore. The "Man in the Moon" refers to several fantastic images of a human face that certain traditions see outlined in the gleaming disk of the full Moon. In November 2013, astronomers using data from the lunar-orbiting twins composing NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, announced that they have been acquiring new and fascinating insight into how this bewitching "face," etched on our Moon's disk, received its captivating and enchanting good looks!
On occasion February will have no full moons and January and March will both have two. In this case, you have two calendar blue moons in the same year. However, there can be no more than one in a year's time or it would not be that rare of an event. Using the Farmer's Almanac description there can be a maximum of one in a year.
GRAIL Mission Puts A New Face On The Moon! Scientific investigation into the origin of lunar impact basins has been hampered because there is a general lack of agreement on their size. The majority of the largest impact basins pock-mark the near-side of the Moon (the Moon's enchanting "face"), and have also been filled in by gushing lava streams. These lava streams have covered up, and rendered invisible, important clues pertaining to the shape of the land.
