Red Moon

The red moon is the red moon in the sky, an astronomical spectacle. This phenomenon usually occurs in the entire eclipse of the month. Because of the deep, purple, blue, green and yellow light absorption of the atmosphere, only the red light can penetrate. The same is true for the red moon in the entire lunar eclipse. The atmosphere reflects red light onto the surface of the moon, so we can still see the red moon hanging in the sky. In the process of the moon's entire eclipse, from this time between "food" and "light", the moon does not disappear in our eyes, but gives a mysterious and elegant bronze, so it is called "red moon."

Blue moon

"Blue Moon" is a popular term that refers to the appearance of two full moons in a month. The second full moon is given a romantic name: "Blue Moon."

Super moon

"Super Moon" is a relatively common astronomical phenomenon. The exact title in Astronomy is near the point of hope. It refers to the New Moon or the full moon, the distance between the moon and the Earth is closer than usual, and the largest and most circular moon visible to the naked eye. Since the orbit of the moon orbiting the ground is non-standard, the distance between the moon and the earth is not constant. As the distance between the moon and the earth changes, the size of the moon looks different. "Super Moon" is 14% larger than the standard moon diameter, 30% greater than the area, and visible to the naked eye, so it's very popular. The time interval between the appearance of the "Super Moon" is about 14 months (which is approximately equivalent to 14 months), which is 413.4 days. Experts predict that the next "Super Moon" will be on February 19, 2019. This day coincides with the Chinese Lunar New Year Lantern Festival, which could trigger people to enjoy the moon again.

Eclipse

The eclipse is a special astronomical phenomenon, when the moon, the earth, and the sun form a straight line, and the moon moves in the shade of the earth, the part that can be illuminated by the sun, some or all of it Direct light illuminates, causing observers on earth to see astronomical phenomena in which the moon is lacking or darkening. The old saying goes, "The solar eclipse is awkward and the lonely eclipse is expected." Therefore, the lunar eclipse will fall on the full moon night, which is, the evening of the 15, 16,

Chinese dynasties have a rich celestial calendar. About 3,000 years ago, our ancestors recorded the eclipse and eclipse. The Yin Dynasty's Yin Dynasty Eclipse, the cultural relic of the last Yin Dynasty Capital, was recorded at Aniang, Henan, and recorded the eclipse and lunar eclipse that was more than 1,000 years ago in BC. During the 242 years of the Spring and Autumn Period, at least 37 solar eclipses were recorded. According to modern astronomers, 33 of them proved reliable and became the most complete eclipse record in ancient times.

The ancient Chinese not only recorded the eclipse and eclipse, but also had a rise in eclipse as early as 1500 years ago. The Dunhuang literature "The Northern Wei Dynasty Taiping Zhenji 11 calendar year following the twelfth calendar day" is China's earliest eclipse material, and it is quite accurate.
