Extended data:

The different phases of the moon are related to the direction of observing the moon. If you look at the moon from the opposite direction to the sun, the moon is completely black, and the moon at this time is called a new moon; On the other hand, if you look at the moon in the direction of the sun, the moon is all bright, and the moon at this time is called the full moon. The change of the moon phase is a process from the new moon to the full moon and from the full moon to the new moon. When the new moon appears, the moon and the sun are on the same side of the earth, which is called the conjunction of the sun and the moon, also known as the "new moon". When the full moon appears, the moon and the sun are located on both sides of the earth, which is called the collision between the sun and the moon, also known as "looking". Therefore, the change of the moon phase can also be called the change of the moon.
