Dette s\u00e6rlige rumteleskop skal efter planen sendes af sted den 1. juli ombord p\u00e5 en SpaceX Falcon 9-raket fra Cape Canaveral Space Force Station i Florida, USA. Efter opsendelsen vil det tage Euclid omkring fire uger at n\u00e5 sin destination, 1,5 millioner kilometer fra Jorden. Dets instrumenter vil derefter blive t\u00e6ndt og grundigt testet i to m\u00e5neder, inden Euclid p\u00e5begynder sin mission!\u00a0\u00a0<\/p>\n<p>Sikke en sp\u00e6ndende mission! Euclid skal hj\u00e6lpe med at indsamle data, der kan give svar p\u00e5 nogle af de st\u00f8rste mysterier inden for nutidens astronomi. Vidste du, at almindelig materie \u2013 det stof, som alt det, vi ser, best\u00e5r af, fra stjerner til galakser, planeter til mennesker \u2013 kun udg\u00f8r omkring 5% af det, der findes derude i kosmos? Du undrer dig m\u00e5ske over, hvad der s\u00e5 er med resten? De resterende 95% kaldes m\u00f8rk materie og m\u00f8rk energi. De p\u00e5virker bev\u00e6gelsen af de ting, vi kan se, s\u00e5som galakser, og ser ud til at f\u00e5 universets udvidelse til at accelerere. De er dog meget g\u00e5defulde, og forskerne indr\u00f8mmer, at de ikke ved ret meget om dem. At forst\u00e5 m\u00f8rk energi og m\u00f8rkt stof er m\u00e5ske den st\u00f8rste udfordring inden for fysikken i dag.\u00a0<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"3500\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2023\/02\/Euclid_electromagnetic_compatibility_tests_successful\" 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\/2023\/02\/euclid_electromagnetic_compatibility_tests_successful\/24720404-1-eng-GB\/Euclid_electromagnetic_compatibility_tests_successful.jpg\" alt=\"This real photo of Euclid shows it undergoing tests before launch into space.

Euclid har et specielt solskjold, der blokerer lyset fra Solen, Jorden og M\u00e5nen, mens teleskopet er rettet mod det fjerne rum. Dens f\u00f8lsomme instrumenter vil kortl\u00e6gge 1\/3 af himlen og dermed skabe det st\u00f8rste og mest n\u00f8jagtige 3D-kort over universet nogensinde! Dette vil omfatte placeringen af milliarder af galakser \u2013 ikke kun hvor de befinder sig nu, men utroligt nok ogs\u00e5 hvor de befandt sig i fortiden. Det skyldes, at jo l\u00e6ngere v\u00e6k en galakse er, jo l\u00e6ngere tid har dens lys taget at n\u00e5 frem til os, og derfor vil vi se den tidligere i den kosmiske historie. Euclid vil skabe et kort over rummet, der d\u00e6kker op til 10 milliarder lys\u00e5r fra os, og kortl\u00e6gge galaksernes position og bev\u00e6gelse gennem det meste af universets historie! Dette vil give forskerne mulighed for at se, hvordan universets form har \u00e6ndret sig over tid.\u00a0<br \/>\u00a0<br \/>Ved hj\u00e6lp af dette fantastiske kort vil forskere p\u00e5 Jorden kunne unders\u00f8ge, hvordan universet har udvidet sig, og hvordan stoffet i det har \u00e6ndret sig over tid. P\u00e5 den baggrund kan vi g\u00f8re forbl\u00f8ffende opdagelser om tyngdekraften, m\u00f8rk energi og m\u00f8rkt stof. Med Euclids hj\u00e6lp vil vi m\u00e5ske endelig kunne l\u00f8se disse mysterier!\u00a0\u00a0<\/p>\n<p><b>Sjovt faktum:<\/b> Mere end 3 500 mennesker fra over 300 institutioner i 21 lande har samarbejdet om at g\u00f8re Euclid-missionen til virkelighed.\u00a0<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1241\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2013\/01\/Euclid_logo\" 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\/2013\/01\/euclid_logo\/12493233-3-eng-GB\/Euclid_logo.png\" alt=\"Euclid has its own logo!
