Therefore, they interpreted that any samples collected from the comet would contain material from the interstellar medium before the formation of the solar system. However, the samples that returned to Earth from NASA\u2019s Stardust mission have revealed material comprised of a variety of events that occurred during the early age of the solar system, as opposed to strictly before the solar system formed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cThe Stardust samples, microscopic grains from a body less than two miles wide, contain a record of the deep past covering billions of miles,\u201d said Dr. Ryan Ogliore. \u201cAfter 18 years of interrogating this comet, we have a much better view of the solar system\u2019s dynamic formative years.\u201d What can samples collected from a comet [\u2026]<\/p>\n","protected":false},"author":706,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1635,8],"tags":[],"class_list":["post-180731","post","type-post","status-publish","format-standard","hentry","category-materials","category-space"],"_links":{"self":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts\/180731","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=180731"}],"version-history":[{"count":0,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/posts\/180731\/revisions"}],"wp:attachment":[{"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/media?parent=180731"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/categories?post=180731"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lifeboat.com\/blog\/wp-json\/wp\/v2\/tags?post=180731"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
