In 2022, observations of Venus using the SOFIA airborne infrared telescope failed to detect phosphine, with an upper limit on the concentration of 0.8 ppb announced for Venusian altitudes 75–110 km. [57] A subsequent reanalysis of the SOFIA data using nonstandard calibration techniques resulted in a phosphine detection at the concentration ...

Researchers’ detection of two gases, phosphine and ammonia, in the clouds of Venus raises speculation about possible life forms in the planet’s atmosphere.
In 2020, Greaves et al. detected phosphine levels of 1–5 parts per billion in Venus' atmosphere using ALMA and JCMT. [21] Historic data from Pioneer Venus also shows the possible detection of phosphine. [22] Phosphine (PH 3) is derived from phosphide (P 3-) through the following interaction with sulfuric acid in Venus' atmosphere:
In September 2020, a team at Cardiff University announced that observations of Venus using the James Clerk Maxwell Telescope and Atacama Large Millimeter Array in 2017 and 2019 indicated that the Venusian atmosphere contained phosphine (PH 3) in concentrations 10,000 times higher than those that could be ascribed to any known non-biological ...
The atmosphere of Venus is the very dense layer of gases surrounding the planet Venus. Venus's atmosphere is composed of 96.5% carbon dioxide and 3.5% nitrogen , with other chemical compounds present only in trace amounts. [ 1 ]
Venus Life Finder is a planned Venus space probe designed to detect signs of life in the Venusian atmosphere. [4] Slated to be the first private mission to another planet, [ 6 ] the spacecraft is being developed by Rocket Lab in collaboration with a team from the Massachusetts Institute of Technology . [ 7 ]
After the tantalizing detection of phosphine (PH 3) in the atmosphere of the planet Venus, and in the absence of a known and plausible chemical mechanism to explain the formation of this molecule, Greaves et al. speculated in 2020 that microorganisms might be present in suspension in the Venusian atmosphere.
