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 · Venus Might Host Life, New Discovery Suggests. The unexpected atmospheric detection of phosphine, a smelly gas made by microbes on Earth, could spark a revolution in astrobiology. By Adam Mann ...
Sep 14, 2020 · Sometimes referred to as our “sister” planet for its proximity to Earth and its similar size, Venus is notoriously inhospitable. The planet’s surface averages a scorching 800 degrees ...

Jan 6, 2022 · The researchers assert that, as the planet’s surface became more inhospitable, microorganisms may have migrated to calmer and less extreme conditions in Venus’ atmosphere. This could explain why microorganisms may be drifting. Atmospheric pressures at 48 to 70 kilometers, or 30 to 43 miles, above the planet’s surface are similar to Earth ...
Feb 1, 2017 · After all, microbes have been found at similar heights in Earth’s atmosphere. The challenge for life on Venus is the planet’s extreme temperature. The surface, at 462º C (864º F), is hot enough to melt lead, and the surface pressure of 92 bar is the equivalent of being almost a kilometer under water.

Jan 1, 2020 · A possible transfer of ~ 10 11 microbial cells from Venus to the Earth's environment in a single injection event, although modest, cannot be ignored. It would require only a small fraction of this inoculant to find an appropriate terrestrial niche to effectively link the biosphere of Venus to that of the Earth.
