This is based on a new study published in the famous magazine Nature astronomy, revealing that a kind of odor and combustible gas related to life on earth has been found in the atmosphere of Venus, and the amount is “amazing”. On September 14, the journal Nature astronomy published a study entitled “phosphine in the clouds of Venus” — a detailed description of a large number of phosphine gases found in the atmosphere of Venus. This gas is considered as a potential biological signal of life and can be used as evidence of life on other planets and celestial bodies. Venus’s atmosphere is full of highly acidic, temperate clouds that contain “an obvious presence of phosphine… Any phosphorus should exist in the form of oxidation,” according to new research. < p > < p > after detailed studies on the steady-state chemical and photochemical pathways, the existence of phosphine gas cannot be explained. There are no known abiotic production pathways in the atmosphere, clouds, surface and underground of Venus, or the transportation from lightning, volcano or meteorite. < / P > < p > these findings are quite exciting, but it should be noted that no life has been found on Venus. Instead, the study shows the existence of biological characteristics – evidence of possible life on the planet. This is an important difference, because at present, life has not been confirmed in Venus’ atmosphere. < / P > < p > biological signals have been proposed as the best way to determine whether life is possible on any particular exoplanet. This evidence is made up of compounds, isotopes, molecules, or similar things that are unlikely to exist without life; they are likely to be the result of life that exists on planets today or at some point in the past. The new study points out that other potential sources of phosphine gas are also possible, including some “unknown photochemistry or geochemistry” in addition to the possible existence of “life”. In order to trace the source of the gas, more research is needed on these findings. On earth, phosphine gas has a unique relationship with life. Although the gas is found elsewhere in the solar system, it is limited to gas giant planets, not rock planets, where it will be rapidly destroyed in the atmosphere. For this reason, the study points out that phosphine gas “meets most of the criteria for biological gas search”, but it is not enough to make a declaration on the discovery of life outside the earth. < / P > < p > the ideal biological characteristic gas should be clear. Organisms should be its only source, and it should have essentially strong, accurate spectral conversion characteristics, without contamination lines – these standards are not always achievable. < / P > < p > after this exciting study was published, NASA commented on the matter, noting that it was not relevant to the work, and that at this time, the agency could not comment on the findings. However, the agency noted that the study was published in a well-known journal and that it believed in “the scientific peer review process.”. < / P > < p > like more and more planetary bodies, Venus has proved to be an exciting place to discover, although it has not yet become an important part of the search for life due to its extreme temperature, atmospheric composition and other factors. Of the next four candidate missions for NASA’s discovery program, two are focused on Venus, as are European envision missions, which NASA is a partner. Venus is also a planetary destination that we can reach with smaller missions. Global Tech
