The cause and timing of the 2021 super red moon "encounter" total lunar eclipse
2021 Super Red Moon and total lunar eclipse will appear at the same time, the time will be at 17:45 pm on May 26, until Ends at 21:51.This is a relatively coincidental celestial phenomenon, that is, a supermoon, a red moon and a total lunar eclipse appear at the same time, because a total lunar eclipse would have produced a blood moon, so generally speaking, this is a total lunar eclipse celestial phenomenon located at perigee.
Introduction to super moon
Super moon is a term coined by American astrologer Richard Noelle in 1979 , is a new moon or full moon when the moon is near perigee.When the moon is at perigee, a new moon occurs, which is called a super new moon; when the moon is at perigee, it is exactly full moon, which is called a super full moon.Because the moon orbits the earth in an elliptical orbit, the distance between the moon and the earth is constantly changing, so the closer the moon is to the earth when the full moon occurs, the larger the full moon will be seen.Supermoons are actually not uncommon.There are 4-6 supermoons every year.
Introduction to the Red Moon
In popular terms, a blood moon is a red moon in the sky, and a blood moon is a spectacle.A red moon usually appears during a total lunar eclipse.This is because the thick atmosphere absorbs all the violet, blue, green, and yellow light, leaving only the red light to penetrate.The same is true for a red moon during a total lunar eclipse.The atmosphere refracts red light onto the lunar surface, so we can still see the red moon hanging in the sky in the shadow of the earth.Folklore:If the moon changes color, there will be disasters.The green is for hunger and worry, the red is for fighting and soldiers, the yellow is for virtue and joy, the white is for drought and mourning, the black is for water, and people are sick and die.
Introduction to total lunar eclipse
Total lunar eclipse is an astronomical term and is a type of lunar eclipse.On the fifteenth and sixteenth of the lunar calendar, the moon moves in the opposite direction to the sun.At this time, if the centers of the earth and the moon are roughly on the same line, the moon will enter the umbra of the earth, resulting in a total lunar eclipse.During a lunar eclipse, for the Earth, the directions of the sun and the moon differ by 180°.Due to the orbits of the sun and the moon in the sky, called the ecliptic and the white path, they are not on the same plane, but at an angle of about 5°.Therefore, only the sun and the moon are located near the two intersections of the ecliptic and the white, respectively, and have the opportunity to form a straight line, resulting in a total lunar eclipse.
The time of the super red moon and total lunar eclipse in 2021
On the evening of May 26, 2021, the largest full moon in 2021 will "combine debut" with a total lunar eclipse, rare astronomical wonders superimposed The formation of a "super red moon".This time, the distance that the moon passes through the earth’s shadow is short, resulting in a short duration of the total eclipse, only 20 minutes from the eclipse to the light.Therefore, if you want to enjoy this "super astronomical phenomenon", you must pay close attention to the local weather and choose a suitable location.If the sky is beautiful, everyone will be able to see the beautiful scene of the moon "slightly drunk" and transformed into a "red moon".
This lunar eclipse will begin at 17:45 on May 26, Beijing time, when the lunar surface begins to eclipse (initial loss).At 19:9, the moon completely entered the earth’s shadow (eclipse), and at 19:19, it reached the maximum occlusion (eclipse).At 19:28, the moon began to reappear (glow), and at 20:53, the moon surface came out of the shadow of the earth (returned); at 21:51, the total lunar eclipse ended, and the entire full moon returned to its former luster.
The cause of the super red moon and total lunar eclipse in 2021
According to astronomers, when the positions of the moon, the earth and the sun in the universe are in a straight line, the earth’s A lunar eclipse occurs when the shadow blocks the moon.Coincidentally, this total lunar eclipse is also the largest of the full moons in 2021, which can be said to be a "super moon" rising with eclipse.In general, lunar eclipses are not uncommon.But when the "Tengu Eclipse Moon" meets the "Super Moon", this enlarged version of the "Super Lunar Eclipse" is more rare.What’s more interesting is that the moon of the day will not only "change face", but also "change color".When the moon completely enters the earth’s umbra, due to the refraction and scattering of sunlight by the earth’s atmosphere, only a small amount of red and yellow light with longer wavelengths can penetrate the atmosphere and shine on the moon, giving everyone the opportunity to see a round of "blood color" during the total eclipse phase.the moon.
