Life like we have on the Earth uses water for its solvent and organic molecules for its building blocks. Hence searches for Earth-like life can focus on habitable zones around stars where liquid water can be stable on planetary surfaces.<\/em><\/p>\n<p><em>But is water the only solvent in which life can exist? Though more exotic solvents (like ammonia, liquid nitrogen, or supercritical carbon dioxide) may exist in extrasolar systems, the only surface liquids outside of Earth that we know about today occur on Saturn&#8217;s smoggy moon Titan.<\/em><\/p>\n<p><em>Dr Barnes will describe these seas, their chemistry, and hydrology, with an eye toward whether they could serve as possible abodes for life. Recent Cassini discoveries show evaporitic bathtub rings and &#8216;salt&#8217; flats around seas, which indicate that at least some materials do dissolve in the lakes. He will also discuss new Cassini RADAR evidence for compositional variations between the seas, and VIMS observations that may show the first sea-surface waves ever seen outside of Earth.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Here&#8217;s a SETI Institute seminar given by Prof. Jason Barnes of the Univ. of Idaho who talks about the possibility of life on the Saturn moon Titan:\u00a0It&#8217;s Life Jim, but Not as We Know It: The Prospects of Life in Titan&#8217;s Seas &#8211;\u00a0SETI Institute\u00a0&#8211; Here is the caption: It&#8217;s Life Jim, but Not as We &hellip; <a href=\"https:\/\/hobbyspace.com\/Blog\/?p=10070\" class=\"more-link\">Continue reading <span class=\"screen-reader-text\">Video: Prospects for life in Titan&#8217;s hydrocarbon seas<\/span> <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[9,41,13],"tags":[],"class_list":["post-10070","post","type-post","status-publish","format-standard","hentry","category-science-and-technology","category-seti","category-space-science"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p34aWK-2Cq","jetpack-related-posts":[{"id":11198,"url":"https:\/\/hobbyspace.com\/Blog\/?p=11198","url_meta":{"origin":10070,"position":0},"title":"Video: Titan&#8217;s lakes","author":"TopSpacer","date":"August 14, 2015","format":false,"excerpt":"A SETI Institute seminar about\u00a0the lakes on Saturn's exotic moon Titan: What do we know about the composition, surface, depth and distribution of liquid on Saturn's largest moon, Titan?
