Herschel, der nu befinder sig i en sikker bane omkring 1,5 millioner km fra Jorden, er begyndt at afsl\u00f8re hidtil ukendte detaljer om stjernedannelse. Nye billeder viser tusindvis af fjerne galakser, der i rasende tempo danner stjerner, samt smukke, stjernedannende skyer spredt ud over M\u00e6lkevejen.<\/p>\n<\/div>\n<p>Herschel er det st\u00f8rste astronomiske observatorium, der nogensinde er sendt ud i rummet, med et hovedspejl, der er fire gange bredere end noget tidligere infrar\u00f8dt rumteleskop. Det g\u00f8r det muligt at unders\u00f8ge de kolde, stjernedannende skyer i vores galakse mere detaljeret end nogensinde f\u00f8r. Et af disse omr\u00e5der, kendt som RCW 120, rummer en nyf\u00f8dt stjerne, der ser ud til at blive en superk\u00e6mpe inden for de n\u00e6ste par hundrede tusinde \u00e5r.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"2545\" data-credit=\"ESA\/Hi-GAL Consortium\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2010\/05\/Stellar_pregnancy_and_birth_in_the_Milky_Way2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2010\/05\/stellar_pregnancy_and_birth_in_the_milky_way2\/17885989-2-eng-GB\/Stellar_pregnancy_and_birth_in_the_Milky_Way.jpg\" alt=\"Stellar pregnancy and birth in the Milky Way\"><\/figure>\n<p>Den unge stjerne, der allerede er 8 til 10 gange tungere end Solen, er omgivet af en k\u00e6mpe sky af gas og st\u00f8v, som den kan tr\u00e6kke n\u00e6ring fra og vokse p\u00e5. Forskerne forst\u00e5r ikke, hvordan stjerner kan svulme op til 150 solmasser, s\u00e5 RCW 120 vil blive n\u00f8je overv\u00e5get for at se, hvordan s\u00e5danne superk\u00e6mper dannes.<\/p>\n<p>Et nyt Herschel-billede viser, hvordan stof i M\u00e6lkevejen samler sig og danner stjerner. \u2018Fr\u00f8ene\u2019 dukker f\u00f8rst op inde i str\u00f8mme af gl\u00f8dende st\u00f8v og gas og danner k\u00e6der af stjernefabrikker, der er flere titalls lys\u00e5r lange. Uden for vores M\u00e6lkevej har Herschel m\u00e5lt infrar\u00f8dt lys fra tusindvis af andre galakser, spredt over milliarder af lys\u00e5r.<\/p>\n<p>Ved at unders\u00f8ge lysstyrken af disse sm\u00e5 lyspunkter har man kunnet p\u00e5vise, at stjerner tidligere dannedes 10-15 gange hurtigere end i dag. Herschel har desuden opfanget stof, der ikke forekommer naturligt p\u00e5 Jorden \u2013 vandmolekyler, der er blevet spaltet af kraftig str\u00e5ling og har f\u00e5et en elektrisk ladning.<\/p>","protected":false},"excerpt":{"rendered":"<p>One year ago, ESA\u2019s Herschel space observatory was launched on a mission to explore the infrared Universe.
