Astronomers who have searched for "proto-earth" for decades have finally found a planet suitable for habitation under certain conditions. And it turned out to be Venus.
Experts from Sweden and the United States have done a lot of research before coming to this conclusion. In their opinion, there is good reason to believe that in ancient times, the planet-sister of the Earth could be inhabited. Moreover, many billions of years before life began on the Earth itself. So, perhaps the Earth will have to give up the palm in the question of habitability in the solar system Venus.
Scientists argue that if certain conditions were now created for Venus, then it would become suitable for settlement. To do this, the planet needs to start rotating sixteen Earth days slower. Then the temperature of Venus will drop approximately to Earth. And even the fact that Venus is closer to the Sun would not be an obstacle, since the high density of the atmosphere would not allow the sun's rays to burn the surface of the planet.
Not to be unfounded, a team of astronomers has created a 3D model that clearly demonstrates how the weather conditions of Venus have changed over the past three billion years. For more meticulous accuracy, scientists have used topographic data from the Magellan probe, which has been transmitting images of Venus to Earth for many years.
It is not for nothing that Venus is called the sister of the Earth. In addition to the close proximity to the location of the orbits, the planets have many similar astronomical indicators. In addition, these two celestial bodies have almost the same mass.
The main differences between the planets are the temperature and density of the atmosphere. The temperature of the Venusian atmosphere is close to half a thousand degrees Celsius. And its density is ninety times that of the earth. For earthlings, these indicators are, to put it mildly, deadly.
Interestingly, back in the twentieth century, a scientist named Carl Sagan came up with his own original way to make Venus habitable. He suggested loading a rocket going there with a lot of different types of algae. Having reached orbit, these algae should have been thrown into the upper atmosphere. It was assumed that the high density of the Venusian atmosphere would prevent the algae from falling to the surface, and they would remain in the "air." So, in a suspended state, they will begin to absorb carbon dioxide, which is the main component of the Venusian atmosphere, and instead, with the help of photosynthesis, they will begin to release oxygen. And, if everything went according to the plan, then in a couple of hundred years Venus would be filled with oxygen that supports various forms of life.
