Technically, this is called biosignature. This was initially considered to be the finding of phosphane in the clouds of the infernal atmosphere of Venus. He suggested that microorganisms could live in them. But detecting gases on distant planets brings with it a number of problems. A new study suggests that we did not find phosphane on Venus, but another, completely common, inorganic gas.
“According to our research, phosphane detection is now much less likely,” Victoria Meadows, an astrobiologist and professor of astronomy at the University of Washington in Seattle, told NBC television.
