Calendar of New Moon and Full Moon in 2023
Introduction to the new moon: The new moon is an astronomical phenomenon, which refers to the situation that on the first day of each month in the lunar calendar, when the moon moves between the sun and the earth, the moon faces the earth with its dark side and sinks with the sun, and the moon cannot be seen on the earth. The original meaning of the word "new moon" is the eyebrow moon that is first seen after the moon and the sun merge into one.
This happened before the sun set on the western horizon, that is, a short time after sunset, so the date of the new moon and the exact time when the event can be seen are closely related to the geographical position of the observer.
The astronomical new moon, sometimes called the Black Moon to avoid confusion, is defined as invisible from the earth when the sun and the moon have the same ecliptic. This moment is unique and has nothing to do with geographical location. In some cases, there will be a solar eclipse.
The reason for the formation of the new moon:?
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, it is completely black, and the moon at this time is called the new moon; On the other hand, if you look at the moon from the direction of the sun, it 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 called "looking". So the change of the moon phase can also be called the change of the moon.
