Venus’ atmosphere reveals potential signs of life — again, scientists say | CNN

Scientists' current understanding of the atmospheric chemistry of Venus cannot explain the presence of phosphine, said Dr. Kate Pattle, a lecturer in the department of physics and astronomy at University College London. "It's important to note that the team behind the measurements of phosphine are not claiming to have found life on Venus," Pattle said in an email. "If phosphine is really present on Venus, it might indicate life, or might indicate that there is Venusian atmospheric chemistry that we do not yet understand."…

Traces of a pungent gas that waft through the clouds of Venus may be emanations from aerial organisms – microbial life, but not as we know it. Astronomers detected phosphine 30 miles up in the planet’s atmosphere and have failed to identify a process other than life that could account for its presence.
