A team of scientists say they've detected a rare gas in the clouds of Venus which is only produced by living organisms on earth, according to a study published on Monday.
"Rocky planets such as Venus and Earth, phosphine can only be made by life—whether human or microbe. Used as a chemical weapon during World War I, phosphine is still manufactured as an agricultural fumigant, is used in the semiconductor industry, and is a nasty byproduct of meth labs. But phosphine is also made naturally by some species of anaerobic bacteria—organisms that live in the oxygen-starved environments of landfills, marshlands, and even animal guts," National Geographic report.
The mystery raises the astonishing possibility that Venus, the planet that comes closest to Earth as it whizzes around the sun, might have some kind of life flourishing more than 30 miles up in its yellow, hazy clouds.
Nothing could live on what passes for land on Venus; its smooth volcanic plains are a scorching hellscape hot enough to melt lead, where the temperatures exceed 800 degrees Fahrenheit. High in the clouds, however, the pressures and temperatures and acidity levels would be less intense — though still vile.
The clouds are far more acidic than any environments where microbes make their home on Earth. And instead of water, the clouds on Venus contain droplets of concentrated sulfuric acid; the atmosphere is so bereft of water that it's many times drier than the driest desert on Earth.
