Photo Illustration by Kelly Caminero/The Daily Beast/GettyPhosphine is a colorless, flammable, toxic gas that smells like rotting fish. Humans manufacture it to use in pest control and the ...
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 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 ...
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:
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 ]
Four years ago, when phosphine was first unexpectedly discovered in Venusian clouds, the finding triggered controversy. Now, scientists say they have stronger proof that phosphine is present and ...
Venus is the second planet from the Sun. It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth. Venus has by far the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover.
