The universe has a long history, and there are many mysteries in the vast universe.
Like what's beyond the far edge of the universe, and are there other advanced civilizations out there?
These questions are too far away to be explored with current technology, but we still have the ability to explore the unsolved mysteries of the solar system.
When the Soviet Union launched the Venus probe in 1989, it passed through the planet's thick clouds to scan the ground with radar and sent back pictures to Earth. Scientists were surprised to find the ruins of nearly 20,000 cities scattered across the surface.
Seen from above, the ruins of the city are in the shape of huge wheels that scatter from the center and contain a large pyramid that some scientists believe is the entrance to the underground city. They estimate that the ruins are at least 8 million years old.
Venus is also called the Morning star because it is always high in the sky before dawn, and because it shares an atmosphere and similar geological structure with Earth, it is called Earth's sister planet. When scientists first looked for a second home on Earth, they thought Venus was the future of humanity 39bet-đua chó-game giải trí -đá gà-đá gà trực tuyến-đánh bài.
So could there have been extraterrestrial civilizations on Venus?
What was Venus really like, and was it really hospitable to life?
Recently when the distance between earth and Venus is only 40 million kilometers, the normal case, using telescopes on earth can see Venus surface, but Venus is covered with thick over the atmosphere, so some unlikely with a telescope, the sixties and seventies of the last century, as the United States and the Soviet union is conducted heated space race, the two countries to find out what Venus's internal, The two countries have embarked on exploration trips to Venus, launching several probes in succession.
The Mariner 2 probe was launched in 1962, but there were no plans to land the probe because people didn't know much about Venus. Mariner 2 flew past Venus at a distance of 34,773 kilometers. Its main mission was to examine the planet's atmosphere, magnetic field and mass data.
Using the Mariner 2 probe, scientists believe that Venus has 60 kilometers of carbon dioxide in the sky and a surface temperature of 460 degrees Celsius.
Over the next few years, the Soviet Union launched several other probes that attempted to enter the inner atmosphere of Venus, but were eventually damaged on the way down due to the planet's terrible atmospheric pressure and heat.
It wasn't until 1970, when Venusian 7 slammed into the surface of Venus at 60 kilometers per hour, that it detected a surface pressure at least 90 times that of Earth and a surface temperature of 470 degrees Celsius.
That means the surface pressure on Venus is equivalent to that of the Earth's deep ocean at 900 meters, and 50 kilometers above the surface there is a layer of sulfuric acid mist about 20 kilometers thick, which is extremely corrosive.
Venus's carbon dioxide atmosphere acts like a greenhouse shield, allowing heat to come in but not out, creating a high temperature and pressure environment that makes Venus a closed oven, completely unsuitable for human life.
The atmosphere is so thick that it's hard for sunlight to reach the surface, so if you were standing on the surface of Venus, you would only see the orange sky during the day. At the same time, the concentrated sulfuric acid above combined with water vapor to form a highly toxic acid rain, eroding the surface of Venus. It's called the surface, but most of the land is actually flowing lava, accompanied by frequent lightning and thunderstorms.
Could life have arisen in such an environment?
It's obviously not going to happen.
After decades of exploration of Venus, we finally know that this terrifying planet, known as Venus, is a hellish world of heat, pressure and acid rain. If life can be produced here, it means that the form and quantity of life may be far more than we can imagine.
Venus in the billions of years ago in fact not now, but the real has some similarities with earth. It is rich in water resources and abundant oxygen, but because Venus does not have a global magnetic field, and was very close to the sun, so in the sun, resulted in the evaporation of water vapor, carbon dioxide is also more and more, the clouds are more heavy.
These thick clouds further prevent heat from escaping, creating a circular, extreme greenhouse effect. This is also a wake-up call to human beings. Our industry is emitting a large amount of greenhouse gases. The global climate has irreversible changes. If we continue like this, perhaps Venus's present is Earth's future.
As for the remnants of cities on Venus, there may be another explanation. Venus has 10% of the surface of the basin, 20% of the highlands and 70% of the plains, almost all over the volcano. Venus has been discovered by humans up to 1600 volcanoes. It is known to have the largest number of volcanoes in the solar system planet.
After volcanic eruptions, magma cooled to form basalt rocks, which in some special landforms can be used to create the shape of urban ruins, so the urban ruins found on the surface of Venus are not surprisingly volcanic, and have nothing to do with extraterrestrial civilization.
