The Royal Astronomical Society announced today that phosphine molecules have been observed from Earth in the atmosphere of Venus. <\/p>\n<p class=\"wp-block-paragraph\">Why does that matter? The phosphine molecule is created either artificially on Earth or \u201cby microbes that thrive in oxygen-free environments,\u201d as RAS describes. <\/p>\n<p><span id=\"more-4695\"><\/span><\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>An international team of astronomers, led by&nbsp;Professor Jane Greaves&nbsp;of&nbsp;Cardiff University, today announced the discovery of a rare molecule \u2014&nbsp;phosphine&nbsp;\u2014 in the clouds of Venus. [\u2026]<\/p>\n<p>Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes \u2014 floating free of the scorching surface, but still needing to tolerate very high acidity. The detection of phosphine molecules, which consist of hydrogen and phosphorus, could point to this extra-terrestrial \u2018aerial\u2019 life.&nbsp;<\/p>\n<\/blockquote>\n<p class=\"wp-block-paragraph\">While the surface of Venus is far too hot to support life as we know it on Venus, scientists haven\u2019t ruled out life in the clouds of Venus being the source of the phosphine molecules. What scientists have ruled out thus far are other sources for the molecules like lightning, sunlight, and volcanic activity due to the amount of molecules observed.<\/p>\n<figure class=\"wp-block-image wp-block-image--obfuscated\"><img decoding=\"async\" src=\"https:\/\/spaceexplored.com\/wp-content\/themes\/ninetofive\/dist\/images\/default-spaceexplored-related-guide.png\" alt=\"Site default logo image\" loading=\"lazy\"><\/figure>\n<p class=\"wp-block-paragraph\">But before we can begin to claim that the atmosphere of Venus is the first known environment to support life beyond Earth, a tremendous amount of investigation is required.

Our nearest neighbour, Venus, has cloud decks that are temperate but hyperacidic. Here we report the apparent presence of phos- phine (PH3) gas in Venus\u2019s atmosphere, where any phosphorus should be in oxidized forms. Single-line millimetre-waveband spectral detections (quality up to ~15<em>\u03c3<\/em>) from the JCMT and ALMA telescopes have no other plausible identification. Atmospheric PH3&nbsp;at ~20 ppb abundance is inferred. The presence of PH3&nbsp;is unexplained after exhaustive study of steady-state chemistry and photochemical pathways, with no currently known abiotic production routes in Venus\u2019s atmosphere, clouds, surface and sub- surface, or from lightning, volcanic or meteoritic delivery. PH3&nbsp;could originate from unknown photochemistry or geochemistry, or, by analogy with biological production of PH3&nbsp;on Earth, from the presence of life. Other PH3&nbsp;spectral features should be sought, while in situ cloud and surface sampling could examine sources of this gas.<\/p>\n<\/blockquote>\n<p class=\"wp-block-paragraph\"><strong>The full paper is available to read for free on <em>Nature Astronomy<\/em>.<\/strong><\/p>\n<figure class=\"wp-block-embed-twitter wp-block-embed is-type-rich is-provider-twitter\">\n<iframe id=\"twitter-widget-0\" scrolling=\"no\" frameborder=\"0\" allowtransparency=\"true\" allowfullscreen=\"true\" class=\"\" style=\"position: absolute; visibility: hidden; width: 0px; height: 0px; display: block; flex-grow: 1;\" title=\"X Post\" src=\"https:\/\/platform.twitter.com\/embed\/Tweet.html?creatorScreenName=apollozac&amp;dnt=true&amp;embedId=twitter-widget-0&amp;features=e30%3D&amp;frame=false&amp;hideCard=false&amp;hideThread=false&amp;id=1305610975329087494&amp;lang=en&amp;origin=https%3A%2F%2Fspaceexplored.com%2F2020%2F09%2F14%2Fvenus-phosphine-molecule-discovery-search-for-life%2F&amp;sessionId=f51e57e5bf2cb6c2b497be69ab9098194583548c&amp;siteScreenName=space_explored&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=500px\" data-tweet-id=\"1305610975329087494\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"500\" data-dnt=\"true\" data-twitter-extracted-i1783314048062187817=\"true\">\n<p lang=\"en\" dir=\"ltr\">\ud83d\udcc8 We have discovered &#8216;phosphine&#8217; on our trending lookup chart. https:\/\/t.co\/SURtMdF5uZ<\/p>\n<p>\u2014 Merriam-Webster (@MerriamWebster) September 14, 2020<\/p><\/blockquote>\n<p><script async=\"\" src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><br \/>\n<\/figure>\n<p class=\"wp-block-paragraph\">Read coverage from <em>The<\/em><em> Verge<\/em>, <em>Wired<\/em>, <em>NASASpaceflight<\/em>, <em>Axios<\/em>, <em>The<\/em> <em>New York Times<\/em><em>, New Scientist, and more.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>While it\u2019s far too soon to claim that life has been discovered beyond our planet, a new scientific discovery provides a tantalizing clue that Venus may be the best place to search for extraterrestrial life.
