Rumfart\u00f8jet forventes at blive opsendt i 2020.<\/p>\n<\/div>\n<p>Euclid er opkaldt efter en ber\u00f8mt gr\u00e6sk matematiker, der ofte omtales som \u201cgeometriens fader\u201d, og som levede omkring 300 f.Kr. Missionen g\u00e5r ud p\u00e5 at s\u00f8ge efter tegn p\u00e5 usynlig m\u00f8rk energi og m\u00f8rkt stof, som menes at udg\u00f8re mere end 95% af det stof, universet best\u00e5r af.<\/p>\n<p>M\u00f8rkt stof er usynligt materiale, der hverken udsender eller absorberer nogen form for lys, og det kan derfor kun p\u00e5vises gennem den m\u00e5de, hvorp\u00e5 dets tyngdekraft p\u00e5virker galakser og galaksehobe. Endnu mere mystisk er m\u00f8rk energi, som menes at frembringe en slags \u201cantityngdekraft\u201d, der f\u00e5r galakserne i universet til at bev\u00e6ge sig l\u00e6ngere og l\u00e6ngere fra hinanden i stadig hurtigere tempo.<\/p>\n<p>Euclid vil v\u00e6re udstyret med et teleskop med en diameter p\u00e5 1,2 m og to videnskabelige instrumenter. I en bane 1,5 millioner km fra Jorden vil den kortl\u00e6gge 3D-fordelingen af op til to milliarder galakser, der d\u00e6kker mere end en tredjedel af hele himmelhv\u00e6lvet. Ved at observere objekter, der ligger op til 10 milliarder lys\u00e5r v\u00e6k, vil den kigge tilbage i tiden for at afsl\u00f8re, hvordan universet har udvidet sig og \u00e6ndret sig i l\u00f8bet af de sidste tre fjerdedele af sin historie.<\/p>\n<p>Ved at bruge Euclid til at unders\u00f8ge, hvordan m\u00f8rkt stof og m\u00f8rk energi p\u00e5virker galaksernes og galaksehobernes bev\u00e6gelse og fordeling, h\u00e5ber forskerne at f\u00e5 en bedre forst\u00e5else af universets m\u00f8rkeste hemmeligheder.<\/p>","protected":false},"excerpt":{"rendered":"<p>ESA has given the final go-ahead for Euclid, an exciting new mission to explore the dark side of the Universe.
