But what processes are responsible for keeping this thick atmosphere from escaping to space? This is what a <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S001670372400677X?via%3Dihub\">recent study<\/a> published in <em>Geochimica et Cosmochimica Acta<\/em> hopes to address as a team of researchers led by the Southwest Research Institute (SwRI) investigated how processes occurring in Titan\u2019s interior could be fueling Titan\u2019s atmosphere, specifically the methane.<\/p>\n<p>\u201cThe presence of methane is critical to the existence of Titan\u2019s atmosphere,\u201d <a href=\"https:\/\/www.eurekalert.org\/news-releases\/1071785\">said Dr. Kelly Miller<\/a>, who is a SwRI research scientist and lead author of the study. \u201cThe methane is removed by reactions caused by sunlight and would disappear in about 30 million years after which the atmosphere would freeze onto the surface.

In the end, the researchers found that temperatures above 250 degrees Celsius (482 degrees Fahrenheit) result in the methane production that is enough to replenish Titan\u2019s atmosphere, along with enough nitrogen production to replenish the atmosphere, as well.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cThe presence of methane is critical to the existence of Titan\u2019s atmosphere,\u201d said Dr. Kelly Miller. \u201cScientists think an internal source must replenish the methane, or else the atmosphere has a geologically short lifetime.\u201d Saturn\u2019s largest moon, Titan, is the only moon in the solar system with a dense atmosphere which is comprised of thick [\u2026]<\/p>\n","protected":false},"author":706,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[],"class_list":["post-204774","post","type-post","status-publish","format-standard","hentry","category-space"],"_links":{"self":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts\/204774","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/users\/706"}],"replies":[{"embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/comments?post=204774"}],"version-history":[{"count":0,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts\/204774\/revisions"}],"wp:attachment":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/media?parent=204774"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/categories?post=204774"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/tags?post=204774"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
