Could Venus have been the first habitable planet in the Solar System?

According to a new theory, the second planet from the Sun, Venus would have been habitable a long time before Earth. The surface of this planet is so hot that it can melt objects, and its sky is very dark because of the toxic clouds emanated by the sulfuric acid. The conditions on Venus were not like this all the time and researchers believe that this was the first habitable planet in the solar system.

This study was first presented at the Conference of the American Astronomical Society in Pasadena.

The study argued that Venus already had a favorable climate and oceans of an approximately 2,000 meter depth when the primitive bacteria began to develop on the surface of the Earth, according to descopera.ro and theguardian.com.

According to some calculations, it was estimated that these oceans existed on the surface of this planet until 715 million years ago, which was a long enough time for the climate to be favorable for microbes to live on that surface .

The planet with the highest temperature

Today, Venus is the planet from the Solar System with the highest temperature, recording 462 Celsius degrees. This is closely related to the small distance between the planet and the sun, but also with the fact that the impenetrable atmosphere consisting of carbon dioxide is 90 times thicker than the Earth's atmosphere.

The Space stations that were sent on this planet's territory by the United States and by the Soviet Union lasted only few hours before they were destroyed.

Mission to analyze the climate of Venus

A more detailed study could provide details about the amount of water that was found on this planet and about when it disappeared completely.

Some information about this will be disclosed after the conclusion of the mission Akatsuki. This mission aims to analyze the climate of the planet Venus. The landing station should have been entering the orbit since the year 2010. But after its main engine exploded, it has spent five years drifting round the sun. Last month, the researchers were able to forward it towards the orbit of the planet, so the mission would be able to provide these answers.

However, to reach a conclusion regarding microbial life on this planet, a new landing space station is needed.
