The moon that went into the darkness appears brightly again [Now in space]

The sun shines on the Earth. The Earth casts a long shadow. The moon is hidden behind the Earth. 'Sun-Earth-Moon' are in a line. The sun shines and the moon rises behind the Earth's shadow.



Little by little, it is sucked into the Earth's shadow. The full moon is gradually cut off and finally disappears.



Eventually, the disappeared moon turns red. The full moon disappears and a 'blood moon' rises. It is a reddish moon. After about an hour, the moon reappears as much as it has been cut off. It gradually emerges from the deep dark tunnel and becomes a bright full moon again.



On the 14th of next month, a total lunar eclipse will occur where the moon completely hides in the Earth's shadow. Based on Coordinated Universal Time (UTC), the total lunar eclipse will begin at 6:26 a.m. on the 14th and end at 7:31 a.m.

It will be visible in the Western Hemisphere where the American continent is located. This total lunar eclipse will not be visible in our country, which is in the Eastern Hemisphere.



In the past, when there was no scientific knowledge about lunar eclipses, a total lunar eclipse was considered an ominous sign. This is because the moon in the sky disappears. Of course, the same was true for a solar eclipse, where the sun is covered by the moon and darkness falls in broad daylight.



Now that we know well about the movements of celestial bodies in the solar system, it is different. It is called a 'space show' that is not seen often. Many citizens of the world, including astronomers and space scientists, even count the days to observe lunar and solar eclipses. It is not an ominous sign, but a mysterious 'space show'.



A lunar eclipse refers to the phenomenon in which the moon enters the Earth's shadow when the 'sun-Earth-moon' are in a straight line. When part of the moon enters the Earth's shadow, it is a partial lunar eclipse, and when the entire moon is hidden in the Earth's shadow, it is a total lunar eclipse. During a total lunar eclipse, the moon slowly slides from the penumbra to the umbra.



When the moon enters the Earth's shadow during a total lunar eclipse, the moon appears red-orange. That's why it's called a 'blood moon.'



Unlike a solar eclipse, a lunar eclipse can be observed without a telescope or filter. However, if you use a telescope, you can see it bigger and in more detail. This total lunar eclipse can be seen in the Western Hemisphere.



There's a reason why the moon appears 'red-orange' when it completely enters the Earth's shadow. The short-wavelength blue light of sunlight is scattered and scattered. On the other hand, the long-wavelength red light passes through the Earth's atmosphere and reaches the moon.



When the moon reflects this red light, it appears red, creating a 'blood moon.'



A total lunar eclipse will also occur on September 8, and it will be observed in Korea as well. It will probably be even more beautiful than the total lunar eclipse in March.
