COROT, som skickades upp i omloppsbana av en ny version av Sojuz-raketen, lyfte fr\u00e5n kosmodromen Baikonur i Kazakstan kl. 15.23 CET. 50 minuter senare placerades den 630 kg tunga satelliten i en perfekt pol\u00e4r omloppsbana, 900 km ovanf\u00f6r jorden.<\/p>\n<\/div>\n<p>Sedan dess har COROT:s 30 cm-teleskop och den mycket k\u00e4nsliga kameran anv\u00e4nts f\u00f6r att studera \u2018stj\u00e4rnb\u00e4vningar\u2019 och s\u00f6ka efter nya v\u00e4rldar. Rymdfarkosten g\u00f6r detta genom att samla in det svaga ljuset fr\u00e5n 120 000 stj\u00e4rnor och vidarebefordra det till en speciell kamera best\u00e5ende av tv\u00e5 delar.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"537\" data-credit=\"CNES\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2006\/11\/Planet_transit_in_front_of_a_star2\" 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\/2006\/11\/planet_transit_in_front_of_a_star2\/17867526-3-eng-GB\/Planet_transit_in_front_of_a_star.jpg\" alt=\"Planet transit in front of a star\"><figcaption>Planet som passerar framf\u00f6r en stj\u00e4rna<\/figcaption><\/figure>\n<p>Den ena halvan av kameran \u00e4r utformad f\u00f6r att uppt\u00e4cka avl\u00e4gsna planeter. Detta sker genom att registrera sm\u00e5 minskningar i en stj\u00e4rnas ljusstyrka n\u00e4r en planet passerar framf\u00f6r den.

Dessa liknar jordb\u00e4vningsv\u00e5gor p\u00e5 jorden och g\u00f6r det m\u00f6jligt f\u00f6r forskarna att l\u00e4ra sig mycket om f\u00f6rh\u00e5llandena inuti varje stj\u00e4rna.
