In 2005, the Cassini spacecraft discovered a giant plume of gas and ice emanating from the moon\u2019s south polar terrain. The source of the plume is a subsurface ocean of liquid water with a volume, temperature, and salinity comparable to Earth\u2019s Arctic Ocean. Enceladus\u2019 subsurface ocean appears to meet the necessary conditions to support life, and frozen ocean water ejected in the plume contains complex organic matter. The outstanding mystery that remains to be solved is the process driving this organic synthesis. One possible mechanism are abiotic hydrothermal reactions on the ocean floor. The other, more enticing possibility is life. This talk will focus on Enceladus\u2019 tremendous astrobiological potential and on the strategies to search for evidence of life in ocean materials ejected in the plume.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Zoom Link for Colloquium 04\/25\/2023 3:00pm PST Please email astrobio@uw.edu for zoom presentation password Presented By Alfonso Davila &nbsp;research scientist&hellip;<\/p>\n","protected":false},"author":1,"featured_media":5690,"comment_status":"closed","ping_status":"closed","sticky":true,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0},"categories":[1,40,12,33],"tags":[120],"acf":[],"_links":{"self":[{"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/posts\/5685"}],"collection":[{"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/comments?post=5685"}],"version-history":[{"count":3,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/posts\/5685\/revisions"}],"predecessor-version":[{"id":5698,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/posts\/5685\/revisions\/5698"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/media\/5690"}],"wp:attachment":[{"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/media?parent=5685"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/categories?post=5685"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/depts.washington.edu\/astrobio\/wordpress\/wp-json\/wp\/v2\/tags?post=5685"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
