Do you know how scary Venus is?
Astronomers call it the Hell Planet because its surface temperature is 500℃. I originally thought it should be silent and dull like purgatory, but I didn’t expect that this planet is very lively. Four hundred volcanoes erupt day and night every day. What’s important is that it is actually located next to the earth!
Legend of Venus
In romantic myths and legends in China and abroad, Venus was once a god wearing a beautiful cloak.
According to relevant historical data, the two words "star" and "taibai" in Chinese both refer to Venus. Their principles are very similar, and they all mean that the surface of Venus can emit extremely bright light. This is true. In addition to the sun itself, the two celestial bodies of the moon and Venus are the brightest.
Therefore, the ancient Chinese called Venus a bright star, not only objectively describing its refractive ability, but also involved many ancient fantasies.
For example, in Journey to the West, Taibai Venus is a civil servant, mainly supervising the good and evil of the world under the order of Jade Emperor .
During the period of the Tang Dynasty, Li Bai was also rumored to be amazing when he was born. Some people say that when Li Bai's mother was nurturing him, she dreamed that Taibai Venus fell into her arms and gave birth to children.
Li Bai was born soon after. When he grew up, Li Bai, who liked to wander around the world, liked to drink and be a hero, and studied Taoism and swords, did have a legendary fairy spirit. His name is Taibai, so later generations respected him as the immortal in the poem.
In the Roman myth, Venus's name is Aphrodite, which is a goddess with both beauty and power. According to legend, she held the power of childbirth and navigation. In the Greek myth, Venus is the embodiment of beauty and love, and people affectionately call it Venus .
In American mythology, Venus also represented peace and beauty. Aztec believes that the light of Venus will bring health to people and dispel demons.
Understanding Venus
Myths and legends about Venus are just idealistic concepts that the ancients did not understand the movement of celestial bodies. As technology progresses further, people gradually understand the real Venus.
It is called the hell planet of the solar system, which is completely different from the beautiful myth. So what does the real Venus look like?
Venus is not unfamiliar to humans, because our exploration of planets in the solar system begins with Venus.
In the 1960s, led by the United States and the former Soviet Union, countries around the world successively embarked on a journey of exploration of Venus. Until now, nearly 50 various probes have been successfully launched towards Venus by Earth civilization.
These instruments provide scientists with a large amount of scientific information about Venus.
For example, on September 14, 2020, two telescopes in Hawaii and Chile discovered a special substance called phosphine through their thick clouds.
You should know that in the eyes of scientists, this substance is equivalent to indirect evidence that can prove the existence of extraterrestrial life.
Although phosphine also exists on the earth, it is closely related to the toxic gases derived from life activities.
, and based on a large amount of data, it shows that Venus once had a large area of oceans on the surface. Then why do people see a desolate on the surface of Venus now?
Scientists believe that this planet has experienced an inhumane greenhouse effect, which finally caused some energy and matter on the surface to be emitted into interstellar space through physical action.
and even the surface of Venus is full of sulfuric acid clouds, but such a complex environment is still believed by many astronomers today: there may still be a chance of surviving microorganisms.
018, people took ultraviolet photos of Venus through the astronomical telescope .The picture shows that Venus has a relatively complex cloud structure. In fact, from the appearance, the sky of Venus is orange-yellow. But there was a dense lightning effect under the clouds and mist. It was recorded to be the largest lightning, which lasted for 15 minutes.
However, Venus' atmospheric environment is still mainly carbon dioxide , and contains a small amount of nitrogen .
The atmospheric pressure of the planet is very high, and the atmospheric pressure of the earth is only 1/92 of its size. This is equivalent to the pressure a grown man feels when he dives in the depth of 1 km of the Earth's ocean.
extraterrestrial civilization
is affected by the strong effect of greenhouses, and the surface temperature of Venus is difficult to drop to 4 Baidu.
A large amount of data shows that under normal operation, this guy's extreme temperature can easily exceed 500℃, and more than 400 volcanoes are erupting day and night, so it is not surprising that people use purgatory to describe this planet.
But what is strange is that Mercury is obviously a planet closer to the sun, and Venus is twice as far away from the sun as Mercury is.
Therefore, the solar radiation energy that Venus can obtain is only 1/4 of the former, but Venus is so hot that it is dizzy.
and it will be subjected to the convection of slow rotation, dense atmosphere and inertia, which will cause its temperature difference between day and night. In other words, it is hot every day, and it is similar to a year.
In addition, this planet has thick clouds. In addition to being like a thick quilt, it can also reflect all the sunlight from stars back to space.
Scientists have found that the thermal radiation of Venus reflectivity is greater than 60%, and its visible light reflectivity is also amazing.
This leads to the sunshine working hard and coming to its doorstep, but people refuse to welcome guests.
Therefore, although Venus is not very far away from the sun, when humans appear on the surface of Venus, they must be unable to see their five fingers, and its sunlight is very visible.
At the same time, Venus is a reckless planet. It has various storms on its surface, but it can be calm inside.
004, scientists observed that when Venus transit occurred, the top of its clouds would sweep strong winds at a speed of 350 kilometers per hour. If this happened on Earth, the consequences would be unimaginable. But Venus' surface is still calm, and I just thought nothing happened.
So some scientists joked that thanks to this thick layer of clouds, Venus has reduced various damage from the depths of the universe. Venus, whose closed stars are becoming hotter and hotter, but scientists were surprised to find that this is also a good phenomenon.
Because of the relatively closed environment, cloud particles under the Venus cloud layer can collide, generate charge, and cause the charge to be transferred from large particles to small particles. The small particles will undergo charge separation during the rising process, which leads to frequent lightning strikes.
Scientists believe that lightning appears frequently on other planets, which may really help the birth and development of life on Earth.
Scientifically proven that Venus is a Earth-like planet because its mass and other parts of the conditions are very similar to that of the Earth. So, Venus may still have many surprises waiting for us to explore.
