Venus lacks sufficient water for its life-sustaining clouds

In 1978, NASA launched the Pioneer Venus mission, consisting of a spacecraft and a group of four small probes thrown into the Venusian atmosphere. There were signs of deuterium in the atmosphere – the heaviest hydrogen isotope that can occur as a result of water pollution. Scientists wondered if Venus might have had more water, and if others had sat around the atmosphere.

Rushing to 2020 and realizing what could happen need phosphine in the atmosphere of Venus. Those scientists he considered the incident about how the flow of water in the Venus-heavy sulfur can allow the tiny microbes found in Venus to get very high droplets and form berries that can be irrigated and continue to reproduce. Although there is a hell on earth, its clouds are stable and hot.

This new paper means that it is very unlikely. The study focuses on “water activity,” or the amount of water used by microbes, measured at a scale of 0 to 1. In this study, the research team attempted to estimate the effect of water on clouds by measuring atmospheric moisture (quantity for water that has achieved atmospheric pressure). Scientists have used it Aspergillus penicillioides, a fungus that can live in the most difficult environments you can imagine, as a basis for understanding the amount of water shortage that an organism can endure while being able to perform electrical and reproductive functions. The answer is the amount of water to 0.585 – mainly the “living limit” of natural resources as we know it.

Using data from astronomical data collected from old Venus missions and using new methods of monitoring the flow of water, Hallworth and his team calculated the size of Venus’s cloud water from 68 to 42 miles[40 to 42 km]above sea level, with temperatures ranging from -40 ° C to 130 ° C. Found water quality positive, 0.004. Hallworth said: “The world’s smallest microorganisms cannot give a chance to Venus.”

The researchers also noted that although the water level was high, Venus’ air was filled with toxic substances that could impair mechanical function (for example, sulfuric acid leaks body fluids).

Some planets are doing well. The group also calculated maritime activity in the Martian clouds at 0.537 (equivalent to the Earth’s stratosphere, as well as smidge under the “living limits” of life on Earth), and in Jupiter clouds at less than 0.585 in temperatures between -10 ° C is 40 ° C. “We can’t say that Jupiter’s clouds could live in it,” says Christopher McKay, a NASA scientist and co-author of the study. “We can say that they do not reduce water activities.”

These findings will need to be confirmed and studied further, but the authors are confident that they will not change, even with two new NASA missions and a brand new ESA project went to Venus in the late decade.

Obviously, there are other caves. “We need to base our conversations on global events on what we know about what we are on earth, because we have a foundation,” says McKay. “But the other part of me hopes that when we find life elsewhere, it’s very different,” is the electrical science that works beyond what we have seen in this world.

And while modern life on Venus may seem impossible from this finding, it does not mean that Venus was always barren. There is a whole hidden history on earth that scientists want to investigate.
