Life on Venus? Astronomers See a Signal in Its Clouds

(14.09.2020)

“This is an astonishing and ‘out of the blue’ finding,” said Sara Seager, a planetary scientist at the Massachusetts Institute of Technology and an author of the papers (one published in Nature Astronomy and another submitted to the journal Astrobiology). “It will definitely fuel more research into the possibilities for life in Venus’s atmosphere.”

Detection of phosphine: new aspects of the phosphorus cycle in the hydrosphere

(26.05.1988)

According to our measurements and calculations, about 5g of phosphorus per day was released as phosphine from an Imhoff tank settling 2,000 m3 per day of raw sewage. Under laboratory conditions, it was also demonstrated that phosphine is released by bacterial reduction from a medium containing inorganic phosphorus.

Phosphine gas in the cloud decks of Venus

(14.09.2020)

Here we report the apparent presence of phosphine (PH3) gas in Venus’s atmosphere, where any phosphorus should be in oxidized forms. Single-line millimetre-waveband spectral detections (quality up to ~15σ) from the JCMT and ALMA telescopes have no other plausible identification.
