US, WASHINGTON (ORDO NEWS) — For about 3 billion years, there could be living creatures on Venus, but about 750 million years ago everything changed and the temperature on the planet jumped to a mark of 462 degrees.
Scientists conducted research in which it was possible to establish that Venus could be suitable for a long time. But then its climate changed and this caused about 80% of the entire planet’s surface to be affected.
Of course, such a statement is quite bold, because most experts believe that Venus is located far from the habitable zone and at the same time is very close to the Sun. In this regard, liquid water could never be on its surface.
In fact, water on Venus, according to astrochemist Herve Cottin, could well have been. Indeed, on other exoplanets, which are much hotter than Venus, it was possible to find water vapor in the atmosphere.
Venus fails to study well enough because landing special equipment on the surface is a huge problem. But nevertheless, the authors of the latest study identified the two most important stages in the evolution of this planet. Venus formed about 4.5 billion years ago.
After 300 million years, it completely cooled. Initially, a huge amount of carbon dioxide was present in its atmosphere, but due to certain processes, the climate on it began to develop in approximately the same way as on Earth. Silicate rocks have eliminated excess carbon dioxide.
About 750 million years ago, the climate on Venus began to change. The reason for this was the activity of volcanoes, which again increased the amount of carbon dioxide. Because of this, the greenhouse effect process began and the temperature on the planet began to skyrocket to incredible levels.
Scientists have developed several scenarios for the development of Venus using special equipment. Regardless of the indicated amount of liquid water, the planet could still maintain a stable climate suitable for the existence of living organisms for three billion years.
