This was the first direct measurement of the Venusian atmosphere in nearly 30 years \u2014 and it looks quite different from Venus&#8217; past. A study published today in Geophysical Research Letters confirms that Venus&#8217; upper atmosphere undergoes puzzling changes over a solar cycle, the Sun&#8217;s 11-year activity cycle. This marks the latest clue to untangling how and why Venus and Earth are so different. <\/p>\n<p>The data sonification in the video translates data from Parker Solar Probe&#8217;s FIELDS instrument into sound. FIELDS detected a natural, low-frequency radio emission as it moved through Venus&#8217; atmosphere that helped scientists calculate the thickness of the planet&#8217;s electrically charged upper atmosphere, called the ionosphere. Understanding how Venus&#8217; ionosphere changes will help researchers determine how Venus, once so similar to Earth, became the world of scorching, toxic air it is today. <\/p>\n<p>Video credit: NASA&#8217;s Goddard Space Flight Center\/Scientific Visualization Studio\/Mark SubbaRao (NASA\/GSFC): Lead Visualizer\/Glyn Collinson (NASA\/GSFC): Lead Scientist\/Joy Ng (USRA): Lead Producer\/Lina Tran (SGT): Lead Writer <\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>During a brief swing by Venus, NASA&#8217;s Parker Solar Probe detected a natural radio signal that revealed the spacecraft had flown through the planet&#8217;s upper atmosphere.<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[15,1,463],"tags":[678,713],"class_list":["post-3934","post","type-post","status-publish","format-standard","hentry","category-robotic-exploration","category-space-exploration","category-videos","tag-parker","tag-parker-solar-probe"],"_links":{"self":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/3934","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3934"}],"version-history":[{"count":1,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/3934\/revisions"}],"predecessor-version":[{"id":3935,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/3934\/revisions\/3935"}],"wp:attachment":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3934"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3934"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3934"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
