What does a lunar eclipse look like, and why there is a lunar eclipse myth

A lunar eclipse is an astronomical phenomenon in which when the Moon moves into the shadow of the Earth, and some or all of the part that could have been illuminated by the sun's rays cannot be illuminated by direct sunlight, making it impossible for observers on Earth to see the ordinary phases of the moon. When a lunar eclipse occurs, the Sun, Earth, and Moon happen to be or almost in the same straight line, so the lunar eclipse must occur on the night of the Full Moon. <

A lunar eclipse is an astronomical phenomenon in which the part of the moon that could have been illuminated by sunlight cannot be illuminated by direct sunlight when the moon moves into the Earth's shadow, making it impossible for observers on Earth to see the ordinary moon phase. When a lunar eclipse occurs, the Sun, the Earth, and the Moon happen to be or almost in the same straight line, so the eclipse must occur on the night of the Full Moon. Be cautious.

1. Lunar eclipse, also known as lunar eclipse, is an astronomical phenomenon in which when the moon moves into the shadow of the earth (the shadow is divided into two parts, umbra and penumbra), the part that can be illuminated by the sun's rays can not be illuminated by direct sunlight, making it impossible for observers located on the earth to see the ordinary moon phase.

2. When a lunar eclipse occurs, the sun, the earth, and the moon happen to be or almost in the same straight line, so the lunar eclipse must occur on the night of the full moon (lunar calendar.

Ten. Five, ten.

6. or 17), as the Shuo Wen says, "the solar eclipse is the new year, and the lunar eclipse is the hope." The Earth's shadow is located in the Earth's orbital plane (ecliptic plane), which does not coincide with the lunar orbital plane (white plane), and the intersection angle of the yellow and white planes is about 5 degrees. During most Full Moons, the Moon is not in the ecliptic plane, but is either north or south, not in the Earth's shadow, so not every Full Moon eclipse occurs. Lunar eclipses occur at least twice a year around the world.

3. There are three types of lunar eclipses:

1) Total Lunar Eclipse: When the entire Moon enters the Earth's umbra. The most recent total lunar eclipse occurred on May 26, 2021.

2) Partial lunar eclipse: When the Moon only partially enters the Earth's umbra, a partial lunar eclipse occurs before and after it. The most recent partial lunar eclipse occurred on July 16, 2019.

3) Penumbral lunar eclipse: At this time, the Moon only passes over the penumbra of the Earth, causing the luminosity of the Moon surface to weaken slightly, so it is less noticeable. The most recent penumbral lunar eclipse occurred on June 5, 2020.

What is a lunar eclipse and how is it formed? Do you understand?

Chinese folklore says that the tengu eats the moon, so what is the total lunar eclipse?

The Sun, the Earth, and the Moon are almost in the same straight line, and when sunlight passes through the Earth's atmosphere, it is refracted and projected on the surface of the Moon, which is red.

"After the moon completely walks into the shadow of the earth, although the sunlight cannot shine directly on the moon, there will still be a part of the sunlight refracted by the earth's atmosphere and shine on the surface of the moon, resulting in a red moon." ”
