Scientists from the University of Wisconsin-Madison are confident that life may be possible on Venus. According to new studies, the lower layers of the atmosphere of Venus contain a living microflora, which acts as a source of abnormal phenomena that are visible in the resulting ultraviolet images.
Venus has always seemed completely uninhabitable. This is indicated by unfavorable conditions on its surface, it is sufficient to note the temperature, which is equal to 465 degrees Celsius, the atmospheric pressure indicators exceed the Earth's land 92 times, and the rains are poured with sulfuric acid. Only at an altitude of about 50 kilometers, the conditions are opposite. The ambient temperature is between 0 and 60 degrees Celsius and the pressure does not exceed 0.4-2 atmospheres.
The authors of the research have determined that on Earth small microorganisms spread in the atmosphere up to a height of 15 kilometers, the mold spores, bacteria, algae and pollen present them. They spread by evaporation or are thrown away by various cataclysms.
It is possible that this could happen on Venus. The water that existed on Venus, the compounds of sulfuric acid and carbon dioxide formed an ancient water vapor that, together with the UV rays, can give energy and nourishment to the microbes. In case of sufficient height, a "habitable zone" for micro-organisms has been defined, suitable for life.
The theory of scientists can confirm images from the planet. Dense clouds cover the entire surface of Venus, exploring their range of visible UV rays and the dark stripes visible since 1927. The true nature of the phenomena has not yet been determined, it is not excluded that this is the position of the current areas habitable. The contrast and the size of the points change in the span of several days and sometimes weeks, while the formations can move over considerable distances. Similar processes on Earth are called meteorological factors.
As scientists have noted, the behavior of "spots" is similar to the life cycle of microbes, which tend to bloom and die as they migrate and move into the atmosphere. Here you can compare with Stygiolobus terrestre or Acidithiobacillus ferroossididans, these organisms feed on sulfur, can absorb UV radiation and are resistant to acids.
The authors point out that all questions can be solved only by organizing a mission on Venus. Up to now, no spacecraft has been able to take samples of its Venus atmosphere, as well as taking any long-term measurement.
