The partial solar eclipse at the end of April is a pity, so what astronomical wonders will arrive in the following May? May will have a rare astronomical spectacle, the long-awaited "Super Blood Moon" for astronomy enthusiasts, a round Hao Moon will turn blood red and last for 5 hours and 21 minutes in the night sky, which is a 7-year spectacle.
The most recent "Super Blood Moon" was staged on November 19 last year, and we were impressed, astronomy enthusiasts took perfect photos of the gradient blood red process of the full moon, which was particularly eye-catching, looked magnificent, and people wondered why a good moon turned blood red.
After 6 months, the "Super Blood Moon" is staged again, so let's find out with excitement what is the "Super Blood Moon" that happens once in 7 years.
May 15 is a seven-year "Super Blood Moon"
On April 30, 2022, a partial eclipse spectacle was staged on Earth, which unfortunately only a very few regions in South America were lucky enough to see, and it didn't matter, because 15 days later, on May 15, there will be a "super blood moon", which according to American astronomers will be the longest "blood moon" from 2022 to 2029, lasting 5 hours and 21 minutes.
"Super Blood Moon" is generally staged together with the "Total Lunar Eclipse" and the Super Full Moon, when the total lunar eclipse is staged, the distance between the Moon and the Earth is shortened by 10%, and the "Super Blood Moon" only appears in the process of the occurrence of the total lunar eclipse, so we only need to know the timing of the total lunar eclipse, and the "Super Blood Moon" stage time is naturally known.
The exact time of the total lunar eclipse is at 21:31 EST on May 15, when the Moon gradually turns blood-red and darkens, the "Super Blood Moon" begins to appear, and the Moon enters the Penumbra region of the Earth. At 22:27 on May 15, the blood-red moon area began to decrease, the lunar eclipse officially began, and the moon officially entered the Earth's umbra.
At 0:02 on May 16, the blood-red moon was completely invisible, a total lunar eclipse appeared, the moon completely entered the earth's umbra, the moon was about 1737 kilometers in diameter, the 38.4 kilometers away from the earth's umbra was about 3 times the diameter of the moon, and the moon's rotation speed was 1.023 km / s, so the moon disappeared for a long time.
At 0:53 on May 16, the moon flew out of the earth's umbra, the moon area began to recover, the total eclipse ended, and at 1:54 on May 16, the moon area was completely restored, the moon left the earth's umbra and entered the earth's penumbra, and we can see the large and round blood-red moon.
It is not until 2:52 on May 16 that the Moon fully emerges from the Earth's penumbra, and the Moon's blood-red moon will disappear and return to its former bright color. From the time the Moon enters the Earth's penumbra and the Moon leaves the Earth's penumbra completely, the whole process lasts 5 hours and 21 minutes.
7 years of the "super blood moon" is about to be staged, I believe that everyone is most concerned about the thing is, which regions can be seen, it is understood that the areas that can be watched are North America, South America, southeast Pacific, Atlantic, Africa and western Europe, but there is no Asia, the United States, Canada, Brazil and other countries can watch, but the mainland can not watch.
In the United States, the "Super Blood Moon" in May is also called "Super Flower Blood Moon", why do you have a flower word? This is because May is the season when flowers bloom, so a "flower" is deliberately added to the middle of the "Super Blood Moon", which means that the "Super Blood Moon" in May is very beautiful.
Why does the moon turn blood red?
The reason why haoyue becomes blood red is related to the earth's atmosphere, the earth's atmosphere is very thick, can extend to an altitude of about 1000 kilometers, after the sunlight penetrates the thick earth's atmosphere, the light becomes red, or close to the red orange, why is this so?
This is actually because the gas molecules in the Earth's atmosphere absorb and scatter part of the light, only the most penetrating red light and orange light can penetrate the past, when the lunar eclipse occurs, the red light and orange light that penetrates the past can illuminate the surface of the moonlight, completely dyeing the moon red, which is the "super blood moon".
Sunlight looks white, no other color, in fact, it is composed of colorful light, we generally divide it into red, orange, yellow, green, blue, indigo, purple 7 colors, light has wave-particle duality, here it is regarded as light waves, different colors represent different wavelengths of light, penetration ability is also different.
Purple light wavelength 435-390 nm, indigo wavelength 450-435 nm, blue light wavelength 492-450 nm, green light wavelength 577-492 nm, yellow light wavelength 597-577 nm, orange light wavelength 622-597 nm, red light wavelength 760-622 nm, the longer the wavelength the stronger the penetration ability, it can be seen that the red light and orange light penetration is the strongest.
When sunlight passes through the Earth's atmosphere, atmospheric molecules absorb and scatter away the light of yellow, green, blue, indigo, and purple, and only the most penetrating red and orange light can pass through, staining the moon red, and the moon will become blood red.
At last
7 years of a "super blood moon" is about to be staged, the starting time is in the United States on May 15, 21:31 Eastern Time, converted to Beijing time, that is, May 16, 9:31, just daytime, unfortunately, this time we have to leave regrets again, there is no way, this is a naturally formed astronomical wonder, is not affected by human influence.
However, the United States, Canada, Brazil and other countries and regions can see, there will certainly be many people to take a lot of blood moon photos, we can only appreciate the photos, a little to make up for our inner regrets.
