Decode the phenomenon of the moon

Usually we cannot see the moon and the stars during the day. Still, there are days when you see the moon "showing" in the sky at the same time as the sun . Please read along to explore this unique phenomenon through the following article.

As you know, during the day we cannot see the stars. The main cause of this phenomenon is because the strong illumination of the sun in the sky obscures the stars' faint aura. Science addicts go even further and tell you that stars actually disappear because the earth's atmosphere contributes to the scattering of sunlight reaching the green planet.

With the star especially the natural satellite of the earth, there are two reasons for it to be seen clearly in the daytime: the moon is bright enough for you to see it in the light blue / blue sky , with time periods the moon is on the earth's horizon at the same time as the sun.

The moon is bright enough to exist in the middle of the day

Maybe you know this or not, the moon does not radiate its light, it just reflects the sunlight to illuminate the sky at night . It is interesting to note that the moon is actually quite dark, so it reflects only about 3% of the sunlight emitted on its surface. This little 3% figure is enough to back up our earth.

In short, though there is almost no place on this earth, the moon is like the sun, but the moonlight is still shimmering than the brightest star in the sky. Therefore, the moon can shine through the white light of the day sky so that we can see it even when the sun is shining (midday)!

The effect of the earth turning itself to the "show" in the moon's daytime

The ability to see the moon from Earth depends entirely on the original position of the moon in its orbit. The moon's rotation around the earth lasts 29.5 days and it appears in different shapes in the sky during this cycle. These shapes are commonly known as the moon's eight-phase common call (below).

The artwork of Carson-Dellosa shows 8 phases in the lunar cycle: new moon (new moon or first moon), waxing crescent, first quarter, waxing gibbous , full moon, waning gibbous (end of the month), last quarter (second half), waning crescent.The moon receives light from the sun (Sun's Ray) and emits it back to the earth.In the direction of the moon's rotation around the earth (Moon's orbit) and the Earth turning around itself (Earth's orbit) are counterclockwise.

The phases of the moon

The shape of the moon when "showing" in the sky depends on the angle it forms with sunlight shining on its surface.

Consider a given part of the moon cycle around the earth, for example, the full moon, because in the sky the moon lies opposite the sun so we will see the moon rise when the sun goes down. Thus, at every full moon, the three sun, moon and earth sets align themselves in a direction where we can see the sunset and the moonrise at the same time. .

However, after the full moon phase, each day passes, the moon will be closer to the sun until it is very close to the largest planet in our solar system (the time of a new moon), growing and diving almost at the same time as the sun. As a result, you will see less of the moon at night and see it more in the daytime.

And because the earth continuously rotates, the moon will "show" above the horizon for about 12 hours on a total of 24 hours a day. On some days, these 12 hours coincide with 12 hours above the sun's horizon. And so unexpected things happen: we can watch the moon during the day!

At that time, the moon began to move away from the sun again until it returned to the full moon and the above cycle was repeated.

Another interesting thing is that we can see the daytime moon almost every day (except for the days close to the new moon phase) but to discover it you need to observe the sky carefully. That's why most amateur observers often find it difficult to see the scene.

For all those who like to observe the stars: the moon "shows up" in the daylight after a full moon until a few days before the new moon. You will not be able to see the moon on the new moon phase because then the illuminated side of the moon is opposite the earth in the opposite direction, not directly opposite, as shown in the image above. You have to watch the phases of the moon every day so you can know the exact time to discover a soft white sphere that shines dimly in the daylight.
