Is it true that Venus had a brilliant civilization many years ago
Sister star of earth
Venus is the closest planet to earth and the most similar in mass and volume to Earth, with 88 percent of the earth and 80 percent of the earth's mass. Venus also has an atmosphere, so it is also called the "sister planet" of Earth.Before the exploration of Venus, astronomers had a high degree of suspicion that there was life on Venus, because the planet was so similar to Earth that if there were millions of species of life on Earth, there should be life on Venus.
The study of Venus
According to a new study published in 2016 in Geophysical Research Letters, Venus may have been habitable billions of years ago. NASA scientists used models used to predict human-induced climate change on Earth to simulate the climate of early Venus. They found that 2.9 billion years ago, Venus probably had an Earth-like temperature of around 11 degrees Celsius. Simulations of Venus 715 million years ago found that Venus is only 4 degrees Celsius warmer than it was earlier, a temperature that would allow the planet's oceans to exist for billions of years. In the early 1960s, both the United States and the Soviet Union began to pay attention to Venus. In July 1962, NASA launched the Mariner Program, and Mariner 1 took off but veered off course and was eventually destroyed. In December 1962, NASA's Mariner 2 successfully flew past Venus. The Soviet Union had its share of failures until 1967, when Venera 4 became the first spacecraft to send messages to Earth through Venus's atmosphere. By 1970, the Venera 7 space probe had actually landed on Venus, transmitting messages for more than 20 minutes before being destroyed by the intense pressure and heat on the surface. In 2012, A Russian space expert, Leonid Ksanfomaliti, claimed to have discovered Venusian life after analyzing photographs taken by the Venera13 probe, which landed on the surface 30 years ago. A scorpion shaped object, a disk and a black lid were found in photographs taken by Venera13, Ksanfomaliti said, and when the detector's camera recorded the scene, the black lid appeared to be moving and ventured to suggest that the morbid features of the objects indicated that they were living beings.
There is no life on Venus
NASA photo analysis experts refuted him quickly, mobile disk is actually from the detector, Venera 13 has two cameras, one in front and one behind, this photo shows the camera lens cover before and after another photo shows the camera lens cover, and both lens cap is not moved, and Ksanfomaliti see "scorpion" is actually to produce "noise" in the process of processing photo, and does not appear in the original image.Since Soviet probes visited the planet, NASA probes have taken more detailed pictures of the Martian surface, and none of it has shown life. NASA's Magellan spacecraft was launched on May 4, 1989, and arrived at Venus on August 10, 1990. During the first eight months of its orbit, Magellan collected radar images of 84 percent of the planet's surface, with 10 times the resolution of the Soviet Venus mission. From 15 May 1991 to 14 September 1992, two more mapping cycles were conducted, covering 98 per cent of Venus without any sign of life.After a great deal of exploration research found that now the surface of Venus is not suitable for life existence, its surface is as high as 460 degrees Celsius temperature, atmospheric pressure 96 times that of earth's surface, the sulfur acid rain falling in the air, the harsh environment that astronomers call Venus planet "hell", such an environment anyway isn't suitable for to life on earth model for the standard of life. So scientists have basically concluded that Venus is lifeless today, and would have been largely lifeless hundreds of millions of years ago, because it would have taken at least hundreds of millions of years for Venus to get to where it is today.
