You must have seen different shapes of the moon such as the crescent moon and the full moon in the night sky. Sometimes the moon may not be visible from any angle in the sky. But what is the cause of this problem?
Whether or not the moon can be seen in the night sky is an astronomical problem that can be investigated scientifically. This issue depends on the direction of the sun’s radiation to the moon. Since the moon does not have its own light and is illuminated and visible by the sun’s radiation, we must look for the answer to this question in the angle of the sun’s radiation to the moon. In this section of Star for your information, we have written about the time when the moon is not visible in the sky.
the first of the lunar month; When the moon is not visible in the sky
Scientifically, when the location of the moon is between the earth and the sun, the part of the moon that is illuminated by the sun’s rays is directly facing the sun, and as a result, we will not be able to see it. In such a situation, the situation of “comparison of the moon and the sun” has occurred, so to speak new moon It is said It should be noted that this situation occurs on the first lunar month and in such a situation, since the dark half of the moon faces the earth, the moon cannot be seen in the night sky.
According to the above, the moon is always present in the night sky, but it cannot be seen from the earth when its dark side is facing the earth.
The light of the sun and the appearance of the moon in different modes
As we mentioned earlier, the moon does not have its own light like other planets and reflects the sun’s light. Therefore, how the moon looks from the earth depends on the way the moon is placed in its orbit and the angle and direction of the light rays; In some periods of time, the dark surface of the moon faces the earth, and in other times, its bright surface; Based on this, the moon is seen in different forms on different days of the lunar month, and the moon is not seen in the sky in a certain period of time.
What is a conjugation?
The conditions of the month that we discussed up to this point are called Muhaq. In fact, when the moon is between the earth and the sun, and the completely bright part of the moon, which is illuminated by the direct sunlight, is behind the earth, so that the moon cannot be seen in the night sky, it is said to be meridian.
Why is the moon seen in different forms from the earth?
From the point of view of astronomy, there is a major reason for seeing the moon in the shape of a crescent, a full moon, and even not seeing the moon in the night sky that we have discussed so far; The moon rotates around the earth once every 30 days (more precisely, every 29.5 days) and during this rotation, different surfaces and angles of it are illuminated by the sun. According to the position of the moon, the sun and the earth and the way each of them is placed in relation to each other in each phase of the moon’s illumination by the sun’s rays, the moon can be seen from the surface of the earth in various ways; The new moon or the conjunction state, the first quarter, the full moon and the last quarter, each of these forms of the month is repeated once.
