The cloud of Venus is full of sulfuric acid and it has 93 times more atmospheric pressure than the Earth has. With 870 degrees Fahrenheit of temperature, it can melt lead. All these characteristics clearly show that life could not exist there. But, the new study has suggested that there could be life on Venus. However not on the surface, but above the surface.
Even though Venus’s surface is very hot and nearly inhospitable for life, the scientists from the University of Wisconsin-Madison suggested that microbes can live in the cloud of Venus. The new study has been published in the journal Astrobiology. As per the scientists, the ancient Venus was much different than Earth. But with the time, its temperature started rising between 650 million and 2 billion and its water got evaporated into its atmosphere. In Venus’s atmosphere, scientists discovered some dark patches which are expected to be caused by light-absorbing bacteria. Now to study more on it, the team is planning to send an aircraft to examine Venus’s atmosphere.
Venus which is also known as the sister of Earth is quite similar in size and mas to the Earth. But its atmosphere consists around 96.5 percent of carbon dioxide and 3.5 percent of nitrogen. As per the scientist, after an altitude of 30 miles, the atmospheric pressure of Venus goes down to nearly 15 pounds per square inch. Well, the 140 degrees Fahrenheit temperature is high but can be tolerated.
Sanjay Limaye, scientists at University of Wisconsin-Madison and lead author of the study stated, “Venus has had plenty of time to evolve life on its own.” Venus had a habitable climate and liquid water for around 2 billion years. He further added, “That’s much longer than is believed to have occurred on Mars.”
In the 1960s and 1970s American and Soviet had conducted a study on Venus which had informed that the lower and middle atmosphere of Venus has such temperate and pressure that can’t produce life. Harold Morowitz, famous biophysicist in 1967 stated that life could there in the clouds. Morowitzh wrote, “While the surface conditions of Venus make the hypothesis of life there implausible, the clouds of Venus are a different story altogether.”
To study more about this, scientists have suggested a way. An aircraft made by Northrop Grumman named the Venus Atmospheric Maneuverable Platform (VAMP) will sail in the atmosphere of Venus will take some samples. It will also carry the instruments which can detect living microorganisms.
