Pomo\u0107u mo\u0107nog ju\u017enoafri\u010dkog radio-teleskopa MeerKAT, istra\u017eiva\u010di su registrovali slabe radio-emisije koje poti\u010du iz ‘kose’ komete 3I\/ATLAS. Rije\u010d je o signalima koji nastaju kada molekuli u ‘kosi’ apsorbuju i emituju zra\u010denje na talasnim du\u017einama karakteristi\u010dnim za hidroksilne radikale (OH).<\/p>\n
Ovi radikali nastaju kada Sun\u010deva svjetlost razla\u017ee molekule vode oslobo\u0111ene tokom zagrijavanja kometarnog jezgra \u2013 proces poznat kao outgassing. Drugim rije\u010dima, kometa se pona\u0161a ba\u0161 onako kako se od komete i o\u010dekuje.<\/p>\n
Ina\u010de, 3I\/ATLAS je tre\u0107i potvr\u0111eni objekat koji nam dolazi iz me\u0111uzvezdanog prostora, poslije \u2018Oumuamue i komete 2I\/Borisov. Otkri\u0107e ovog novog putnika odmah je privuklo veliku pa\u017enju, jer svaki takav objekat predstavlja priliku da uporedimo Sun\u010dev sistem sa drugim \u2013 potpuno nepoznatim \u2013 djelovima galaksije, pi\u0161e astronomija.org.rs<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Pomo\u0107u mo\u0107nog ju\u017enoafri\u010dkog radio-teleskopa MeerKAT, istra\u017eiva\u010di su registrovali slabe radio-emisije koje poti\u010du iz ‘kose’ komete 3I\/ATLAS<\/p>\n","protected":false},"author":1,"featured_media":443662,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","inline_featured_image":false,"footnotes":""},"categories":[14],"tags":[],"class_list":["post-444826","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-vijesti"],"_links":{"self":[{"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/posts\/444826","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/comments?post=444826"}],"version-history":[{"count":1,"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/posts\/444826\/revisions"}],"predecessor-version":[{"id":444829,"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/posts\/444826\/revisions\/444829"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/media\/443662"}],"wp:attachment":[{"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/media?parent=444826"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/categories?post=444826"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.pcnen.com\/portal\/wp-json\/wp\/v2\/tags?post=444826"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
