Water is preserved in carbonaceous chondrites as hydroxyl and\/or H2O molecules in hydrous minerals, but has not been found as liquid. To uncover such liquid, we performed synchrotron-based x-ray computed nanotomography and transmission electron microscopy with a cryo-stage of the aqueously altered carbonaceous chondrite Sutter\u2019s Mill. We discovered CO2-bearing fluid (CO2\/H2O &gt; ~0.15) in a nanosized inclusion incorporated into a calcite crystal, appearing as CO2 ice and\/or CO2 hydrate at 173 K. This is direct evidence of dynamic evolution of the solar system, requiring the Sutter\u2019s Mill\u2019s parent body to have formed outside the CO2 snow line and later transportation to the inner solar system because of Jupiter\u2019s orbital instability.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Akira Tsuchiyama, Akira Miyake, Satoshi Okuzumi, Akira Kitayama, Jun Kawano, Kentaro Uesugi, Akihisa Takeuchi, Tsukasa Nakano, Michael Zolensky Science Advances, 21 Apr 2021:Vol. 7, no. 17, eabg9707DOI: 10.1126\/sciadv.abg9707 LINK (OPEN ACCESS)PDF (OPEN ACCESS) Supplementary Materials&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9,18,49,81,47],"tags":[1241,3273,105,1834,1855],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/27405"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=27405"}],"version-history":[{"count":3,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/27405\/revisions"}],"predecessor-version":[{"id":27409,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/27405\/revisions\/27409"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=27405"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=27405"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=27405"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
