A group of astrophysicists from Switzerland conducted new simulations of atmospheric marvels on Earth and Venus in the early and late stages of elaboration. The study showed that Venus noway had the conditions for rush from water vapor in the atmosphere. Thus, in the history of our neighbor, the emergence of life like the earth was insolvable in principle Venus could be the twin of the Earth, since in terms of weight, size and structure it’s nearly identical to our earth. But she’s much near to the Sun, and this decided her fate. Extreme temperature and pressure on the face of Venus don’t indeed come near to talking about the possibility of terrestrial life in similar conditions Still, scientists were bothered about whether Venus had ages with further favorable conditions? For illustration, did it have abysses – implicit incubators for the birth of life Former exploration has suggested that Venus may have been a much more sociable place in the history, with its own abysses of liquid water.
Research shows that Venus never had water in the form of oceans
A group of astrophysicists from the University of Geneva (UNIGE) and the National Center of Capability for Research (NCCR) Globes Switzerland tried to find out if there was liquid water on Venus in the form of abysses. The results were published in the journal Nature We modeled the climate of Earth and Venus at the morning of their elaboration further than four billion times agone, when the face of the globes was still molten. The high temperatures associated with this meant that any water had to be present in the form of brume, like in a giant pressure cooker,
. – explained one of the authors of the composition, Martin Turbet.
For the work, the scientists took field-proven Models of the geste of the Earth’s atmosphere, which are used to pretend and prognosticate climate marvels that do on the earth moment. Using the model, scientists delved how the atmospheres of the two globes would evolve over time and whether abysses could form With the Earth, everything is more or less clear, but for Venus it turned out that in its conditions water vapor in the atmosphere could noway condense and fall on the earth as rain. Humidity has always remained in the air, which was eased by atmospheric processes during the elaboration of Venus.The reason for this geste of the atmosphere is the propinquity of the Sun and the marvels in the air caused by this propinquity. In particular, shadows on Venus formed on the night side and created a important hothouse effect, which noway allowed the earth to cool down enough for the conformation of condensation in the atmosphere.
The Earth was much more fortunate with this. Also, the hothouse effect in the early stages of elaboration helped our earth not turn into an icy world while the Sun was fairly weak. At the same time, the conditions for condensation of water in the atmosphere were favorable, and water gradationally fell on its face and formed natural budgets, where, as it’s believed, life began The conclusions of scientists are so far only a thesis, supported by certain compliances of the earth’s climate. It’ll be possible to check it by studying Venus more nearly, which the space agencies of the United States, China and India are going to do towards the end of this decade.
