A full moon will be lighting up the skies for the first time in 38 years on Christmas Day this year.
A NASA spokesperson aired this news while revealing that the full moon will be observable and will reach its peak at 6.11am. Moreover, while further revealing information regarding this celestial phenomenon, NASA said that a full moon will not reoccur again on Christmas Day until 2034.
Because this is the last full moon of 2015 in December; therefore it is called the Full Cold Moon or Moon before Yule. Moreover, previously this year two super blood moons lit up the skies in April and September for the first time in three decades.
According to the scientific explanation of this celestial phenomenon, a full moon is the lunar phase that occurs when the moon is completely illuminated as seen from the Earth.
A full moon occurs when moon comes in a position opposite to the Sun (when it is on the opposed side of the Earth from the Sun; more accurately, when the ecliptic longitudes of the Sun and Moon differ by 180 degrees).This means that the hemisphere of the Moon that is facing the Earth is almost fully illuminated by the Sun and appears round, while the far side is almost completely unilluminated.
