Sep 14, 2020 · But the presence of life is far from being the only possible explanation. One phosphine-producing process here on Earth is volcanic activity. And while the team ruled this out, finding that volcanic activity is insufficient and citing a 2015 paper, research from earlier this year suggests Venus may be more volcanically active than previously ...
Sep 14, 2020 · A proposed life cycle for microbes in Venus’ atmosphere. (1) Dehydrated microbes survive in a vegetative state in Venus’ lower haze layer. (2) The spores are lifted by updrafts into the ...
Sep 14, 2020 · Phosphine on Venus - Lead scientist Jane Greaves explains the discovery. The team detected phosphine in Venus’ clouds at a concentration of 20 parts per billion, the authors write in the study ...

Jul 29, 2024 · However, Greaves warned, even the presence of both phosphine and ammonia wouldn’t be evidence of microbial life on Venus, because there’s so much information missing about the state of the planet.
Jun 15, 2022 · Here’s how it works. Venus' atmosphere bears no signs of microbes eating or pooping, suggesting that the odd chemical composition of the planet's clouds cannot be explained by extraterrestrial ...
Sep 14, 2020 · The best evidence for life beyond Earth has been found in the most surprising of places – the atmosphere of Venus. A team led by Jane Greaves, who is a professor at Cardiff University, has detected the presence of phosphine gas in Venus’ clouds. The intriguing thing about phosphine, which is a molecule formed of three hydrogen atoms and one ...

The unexpectedly high levels detected on Venus could point to a floating microbial biosphere, the researchers suggested in a paper published in Nature Astronomy. But almost immediately, other astronomers began to criticize the results, with four independent studies pointing out questionable methods or failing to reproduce the results.
