The research was based on data related to the chemical makeup of the planet\u2019s atmosphere.<\/p>\n<p>Scientists have long considered whether Venus once held liquid water, even possibly large oceans. Such research was based on the fact that Venus is like our own planet in many ways. It is a rocky planet similar in structure and size to Earth and is also our closest planetary neighbor.<\/p>\n<p>But the latest study provides evidence that Venus has likely always been the hot, extremely dry planet it remains today. Researchers from Britain\u2019s University of Cambridge led the study. It recently <a class=\"wsw__a\" href=\"https:\/\/www.nature.com\/articles\/s41550-024-02414-5\">appeared<\/a> in the publication <em>Nature Astronomy<\/em>.<\/p>\n<p>The researchers\u2019 data examinations led them to conclude that both the surface and interior of Venus remain dry. The team said the strongest evidence that Venus once had large amounts of water would be the discovery of some water inside the planet today. But the study provided no evidence of that.<\/p>\n<p>Since water is considered an important element for supporting life, the researchers also suggest that Venus was likely never habitable, or able to support life.<\/p>\n<p>The lead writer of the study was Tereza Constantinou, a doctoral student at the University of Cambridge&#8217;s Institute of Astronomy. She told Reuters news agency, &#8220;We suggest that a habitable past would be associated with Venus&#8217; present interior being water-rich, and a dry past with Venus&#8217; present interior being dry.\u201d<\/p>\n<p>The researchers <a class=\"wsw__a\" href=\"https:\/\/www.cam.ac.uk\/research\/news\/researchers-deal-a-blow-to-theory-that-venus-once-had-liquid-water-on-its-surface\">explained<\/a> they attempted to measure the current destruction rate of molecules in water, carbon dioxide and carbonyl sulfide in Venus\u2019 atmosphere. The state of the planet\u2019s atmosphere is linked to volcanic activity, the team said.<\/p>\n<p>\u201cVolcanism, through its supply of gases to the atmosphere, provides a window into the interior of rocky planets like Venus,\u201d the researchers wrote <a class=\"wsw__a\" href=\"https:\/\/www.cam.ac.uk\/research\/news\/researchers-deal-a-blow-to-theory-that-venus-once-had-liquid-water-on-its-surface\">in a statement<\/a>. \u201cAs <strong>magma<\/strong> rises from the <strong>mantle<\/strong> to the surface, it releases gases from the deeper portions of the planet.<\/p>\n<p>Volcanic explosions, or eruptions, can provide information on the amount of water contained deep below a planet\u2019s surface, the scientists said.<\/p>\n<p>On Earth, for example, volcanic eruptions mostly release steam, a <strong>vapor<\/strong> created when water gets heated. Measurements of volcanic gases on Earth have shown they release about 60 percent water vapor.<\/p>\n<p>But the researchers said their examinations suggested volcanic gases released on Venus were less than 6 percent water vapor. This persuaded the team to conclude that the planet\u2019s interior \u2013 the source of the magma that releases volcanic gases \u2013 must be very dry.<\/p>\n<p>The team noted that scientists have had two leading theories on the history of water on Venus. The first is that the planet had a moderate climate for billions of years, with liquid water flowing over areas of the surface. Over time, widespread volcanic activity likely led to extreme heat and dry conditions that made the water disappear.<\/p>\n<p>The second theory imagined Venus as being very hot from the beginning, preventing liquid water from ever forming on the surface.<\/p>\n<p>Constantinou said, \u201cBoth of those theories are based on climate models, but we wanted to take a different <strong>approach<\/strong> based on observations of Venus\u2019 current atmospheric chemistry.\u201d She added that the team did not find evidence that any chemicals being removed from the atmosphere were later being restored.<\/p>\n<p>This provides strong evidence that Venus has a very dry interior today, the scientists concluded. &#8220;The atmospheric chemistry suggests that volcanic eruptions on Venus release very little water, <strong>implying<\/strong> that the planet&#8217;s interior\u2026is equally dry,\u201d Constantinou said.<\/p>\n<p>She added that her team \u201cwould have loved to find that Venus was once a planet much closer to our own.\u201d However, Constantinou noted the finding suggests that researchers should center their searches \u201con planets that are mostly likely to be able to support life \u2013 at least life as we know it.\u201d<\/p>\n<p>I\u2019m Bryan Lynn.<\/p>\n<p><em>Bryan Lynn wrote this story for VOA Learning English, based on reports from Reuters and the University of Cambridge. <\/em><\/p>\n<div class=\"wsw__embed\">\n<div id=\"quizId7889652\" class=\"quiz quiz--embedded\">\n<h2>Quiz &#8211; New Study Examines Whether Venus Had Liquid Water<\/h2>\n<div class=\"quiz__body quiz__body--flex quiz__body--embedded\">\n<div class=\"quiz__main-img\">\n<figure class=\"media-image js-media-expand\">\n<div class=\"img-wrap\">\n<div class=\"thumb\">\n<img decoding=\"async\" src=\"https:\/\/gdb.voanews.com\/69bb343b-7768-4227-b8dc-0cec96267826_cx9_cy0_cw83_w250_r1.jpg\" alt=\"Quiz - New Study Examines Whether Venus Had Liquid Water\"\/><br \/>\n<span class=\"ico ico-fullscreen ico--media-expand ico--rounded hidden\"\/>\n<\/div>\n<\/div>\n<\/figure>\n<\/div>\n<div class=\"quiz__intro m-t-md ta-c\">\n<h4 class=\"fs-xl\">Start the Quiz to find out<\/h4>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><strong>___________________________________________<\/strong><\/p>\n<h2 class=\"wsw__h2\">Words in This Story<\/h2>\n<p><strong>magma<\/strong><strong> <\/strong><em>\u2013 n.<\/em> hot liquid rock found just below the surface of the Earth<\/p>\n<p><strong>mantle <\/strong><em>\u2013 n.<\/em> a layer of something that covers a surface<\/p>\n<p><strong>vapor<\/strong><strong> <\/strong><em>\u2013 n.<\/em> many small drops of liquid that form in the air<\/p>\n<p><strong>approach <\/strong><em>\u2013 n. <\/em>the way something is done<\/p>\n<p><strong>imply<\/strong><strong> <\/strong><em>\u2013 v.<\/em> to communicate an idea or feeling without saying it directly<\/p>\n<\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/learningenglish.voanews.com\/a\/new-study-examines-whether-venus-had-liquid-water\/7887493.html\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new study suggests that Venus likely never had water flowing on its surface.
