Den 14. juni, en m\u00e5ned etter oppskytingen fra Kourou i Fransk Guyana, fjernet ESAs Herschel-teleskop sitt beskyttende \u2018objektivdeksel\u2019. Selv om det fortsatt var under testing, bestemte oppdragsteamet seg for \u00e5 fremskynde Herschels f\u00f8rste observasjoner. M\u00e5let deres var et av de vakreste objektene p\u00e5 himmelen \u2013 M51, ogs\u00e5 kjent som Virvelgalaksen.<\/p>\n<\/div>\n<p>Herschels dristige \u2018forh\u00e5ndsvisning\u2019, som ble gjort umiddelbart etter at teleskopets deksel ble \u00e5pnet, overgikk alles forventninger. Testbildene av den ber\u00f8mte spiralgalaksen ble tatt i tre farger for \u00e5 fremheve ulike trekk. De viste seg \u00e5 v\u00e6re de skarpeste bildene av \u00abWhirlpool\u00bb som noensinne er tatt i infrar\u00f8dt lys, og viste tydelig den overlegne ytelsen til Herschel, det st\u00f8rste romteleskopet som noensinne har v\u00e6rt i bane. Og dette var bare et glimt av det som skulle komme.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1024\" data-credit=\"ESA and the PACS Consortium\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2009\/06\/M51_Herschel_image_at_160_100_and_70_microns2\" 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\/2009\/06\/m51_herschel_image_at_160_100_and_70_microns2\/17868525-2-eng-GB\/M51_Herschel_image_at_160_100_and_70_microns.jpg\" alt=\"M51 Herschel image at 160, 100 and 70 microns\"><figcaption>Herschel-bilde av M51 ved 160, 100 og 70 mikron<\/figcaption><\/figure>\n<p>Whirlpool-galaksen ble oppdaget i 1773 og var den f\u00f8rste galaksen man noensinne hadde sett med en spiralstruktur.
