Discover when the "Smiley Moon" will appear in the Arab world.

On Saturday night, one of the most important features of the moon, the skies of Saudi Arabia and the Arab region, is known as the "smiling moon" on the moon.

The head of the Astronomical Society of Jeddah, the engineer Majid Abu Zahra, posted on his Facebook social networking page "after sundown Saturday: watch out for the lunar zone called" Mir Kriosium ", which will be seen in Arabia Arabia and the Arab region, an opportunity for amateur photography. "

For what is called "the smiling face of the moon", engineer Abu Zahra pointed out that when the region is in an appropriate position for the observer from the surface of the earth, it looks like to a smiling face if it is seen through the telescope, although in reality.

He added that this smiling face appeared when the Mir-Kerysium area was in the field of vision and the sunlight was crossing the edge of the mountain. The curved, mouth-like hills reflect the bottom of the two mouths that represent the eyes. This view is repeated at the beginning of each lunar month.

The US space agency "NASA" earlier revealed the reason for seeing a smiling face on the moon, explaining that this was due to the uneven distribution of huge collision pools caused by the impact of asteroids on the moon.

Maria Zuber, researcher at the Massachusetts Institute of Technology, said, "We now know that dark spots are huge lava-filled collisions, caused by asteroids four billion years ago," said Maria Zuber.

The researcher explained that the data indicates that the near and far sides of the moon have been subjected to similar collisions, but they interact with them in different ways.
