Was there life on Venus?

Smoke and soot indispensable attributes of the apocalypse in many ancient legends and works of art. Thus, for example, imagine a doomsday Albrecht Durer.
Romantic Venus is the name is misleading, the situation on the planet is more like hell.
The temperature on Venus' surface reaches 470 degrees Celsius.
The outlines of city buildings are lost in the smoke, which is suffocating blanket wraps metropolis. Because of this, breathe in the city, already heated up to the limit, it becomes impossible. In rural areas, the fire shamelessly devoured entire villages. Maddened by thirst, wild animals, forgetting about self-preservation instinct, go to the dwelling of a person in search of life-giving water. The screenplay - disaster? . To submit to the greenhouse effect in all its glory, you can look at the next Venus. This sister of the Earth is fraught with mystery no less than Mars. That she can tell what future awaits our planet. Apocalypse, accompanied by fire, smoke and ash, often described in the ancient traditions. Smoke and soot from the Muscovites cause a similar association. Someone joked that the burning smell of peat Armageddon, someone remembers the plagues, and someone says about the end of the world on the Mayan calendar in 2012. This is not surprising. All sources - from Hindu mythology to the Bible prophecies - suggest that the Apocalypse is sure to be accompanied by a fiery ... Thus, in ...

The scenario with the smoke and soot, and is mentioned in the predictions of the Mexican Indians and the ancient Buddhist sources, and the era of the sixth sun, which the Mayans predicted the beginning of 2012, will bring the fire. According to the calculations of the ancient Greek philosopher Heraclitus of Ephesus, the world must die in a fire every 10 800 years.

All of these prophecies, if formalized, could perfectly illustrate the scientific report on the greenhouse effect. And despite the fact that the very fact of global warming, many scientists questioned, the anomalous warming of the planet - the question is still relevant. Another thing is that it may be the culprit is not the person. Whence comes the threat may be describe in detail a neighbor of the Earth - Venus. The opinions of scientists that this planet was once suitable for life, today we hear more and more. According to one version, blooming planet from global cataclysm was an atmosphere almost entirely composed of carbon dioxide permeable to sunlight. As a consequence, huge temperature on the surface, destroying all life. Do not expect a similar fate the Earth?.

Hello, my sister.

Venus was lucky with the image. Its very name evokes romantic associations. Venus is a harbinger of the dawn and early morning or at dusk flaunts the brightest point in the sky. Astronomers her affectionately called Earth's sister planet because it is closest to our planet and the two celestial bodies are very similar in size. Thus, the radius of the planet is 6356 miles, and Venus - 6051. A thick layer of clouds, in which there are no breaks, makes it impossible to see its surface. Because of the paucity of scientific data about the middle of last century was common assumption is that on Venus may be suitable conditions for life. However, several successful flights of the Soviet apparatus to the planet dispelled this myth - it turned out that the situation on the planet which is more like hell. ... - The atmosphere on the planet about a hundred times thicker than Earth's, and almost entirely composed of carbon dioxide. Only in the early 70s of last century, scientists have found out of the clouds, which are observed by Mikhail Lomonosov. It turned out that they are composed of highly concentrated - 75 percent - of sulfuric acid. Is not it hell? ...

Paradoxically, but in this ... ... Only here it is contained mainly in carbonates and calcareous sediments on the ocean floor, and on Venus, as carbon dioxide in the atmosphere. If the oceans will warm up the current pace, gradually evaporating, then the gas can get out of deposits ...

In the Venusian clouds of sulfur in the Earth's stratosphere, too, is an analog - sulfuric acid aerosols, as consisting of highly concentrated sulfuric acid. Of course, they are far from being content, which is observed on Venus, but this coincidence makes you wonder.

Despite the fact that Venus is much closer to the Sun than the Earth, the two celestial bodies are approximately the same radiation. But almost half of the solar ultraviolet radiation on Venus is neutralized at the level of the clouds, where the addition of sulfuric acid there is a mysterious ultraviolet absorber - to understand its nature, scientists can not yet.

Perhaps billions of years ago, in common with our planet was much more. For example, Venus could have a liquid core and, accordingly, its magnetic field like Earth. Moreover, it is likely that in the past on the surface of the planet in the abundance of water could be present. So far, however, at this point only indirect signs of. ... - Apparently, the water has evaporated, and the light hydrogen, which could enter into its composition, over time, vanished from the atmosphere of Venus. The existence of the ocean in the past would indicate the presence of carbonates, but they are not found on Venus ... However, without evidence, many scientists believe that Venus could have been a flourishing planet, which has become the victim of a global cataclysm. Venus is considered a ... While on missions to Mars, our country did not develop all the time, every Soviet expedition to Venus ended with a triumph - for now it is our scientists can boast that their staff have reached the surface of this planet, starting with ... In recent years the initiative, however, caught with the European Space Agency orbiter Venus Express. Based on these various missions, Western scientists today took to put forward one by one bold hypothesis about the past Venus.

American expert on the terrestrial planets, Dr. David Grinspoon of the Southwest Research Institute drew attention to the fact that the surface of Venus are surprisingly young. Its average age is 500 million years old and the oldest rocks - about 700 million, despite the fact that the formation of planets happened next five billion years ago. Thus, the age of the rocks on the Martian surface is about 3.8 billion years of Earth - more than 4 billion. According to Dr. Grinspoon, the reason for such a radical rejuvenation could become a global catastrophe is the starting point of which was the strongest greenhouse effect. After evaporation of the water on the planet tectonic movements almost completely stopped, and the heat is beginning to accumulate not only on the surface, but inside, which caused the melting of the entire cortex.

Water on Venus could evaporate elementary. So says an expert at Oxford University, Colin Wilson. It draws on data from Venus Express station. ... Another question is how was the development of the greenhouse effect. Was it gradual?.

Shed light on what is happening may be the Russian project ... Orbiter itself with the latest instrumentation to observe the behavior of the planet and its atmosphere. Astronomers plan to reveal the secret sverhrotatsii - a phenomenon which causes the planet's atmosphere rotate up to 60 times faster than the planet itself. In the midst of ... According to the results of their work, perhaps, be able to clarify the nature of the substance that protects the Venus of excess ultraviolet radiation. But most importantly - the planet will go straight to the lander, which will be able to work on the surface of up to two hours. ... - Long-lived plant - something for the future. After 2020 there will be vehicles that are capable to work on Venus to two months '.

Whatever the result, in any case, it will allow us to learn more about the future of the Earth. ... And it's like to make a generalized scientific conclusion on the basis of a single source ... In this sense, the question: ...

... This summer is abnormally hot, and the next will probably be cold. But what will turn this instability? . Perhaps new studies prompt, what are the disasters of the summer - short-term whim of nature or the beginning of a long process, in which the Earth will turn into a Venusian hell.

Maxim Morozov.

It is believed.

In greenhouse conditions.

Mikhail Sinitsyn, a member of the National Astronomical Institute of the P. to. Sternberg:.

- Evidence that Venus could have been life, there is no. And imagine that the atmosphere of this planet somehow enlarged to the size of 90 atmospheres, it is difficult. Rather, its real ... Therefore, by the way, and there are theories of fantasy about what it is on Venus, not Mars, you can create the conditions for the resettlement.

Hakan Shvedov, a specialist European Space Agency:.

- ... On Earth, were formed during the evolution of the ideal conditions for the presence of water in abundance and the origin of life. Perhaps something similar happened on Venus as a result of certain events did not turn the planet into a hot ball of. This may be due to the fact that Venus is closer to the sun and under the influence of water ... But do not rule out that he could play an important role greenhouse effect.
