ESA har gett det slutgiltiga klartecknet f\u00f6r Euclid, ett sp\u00e4nnande nytt uppdrag f\u00f6r att utforska universums m\u00f6rka sida. Rymdfarkosten f\u00f6rv\u00e4ntas skjutas upp \u00e5r 2020.<\/p>\n<\/div>\n

Euclid har f\u00e5tt sitt namn efter en ber\u00f6md grekisk matematiker, som ofta kallas \u201cgeometrins fader\u201d och levde omkring 300 f.Kr. Uppdraget \u00e4r att s\u00f6ka efter bevis p\u00e5 osynlig m\u00f6rk energi och m\u00f6rk materia, som tros utg\u00f6ra mer \u00e4n 95% av det material som universum best\u00e5r av.<\/p>\n

M\u00f6rk materia \u00e4r osynligt material som varken avger eller absorberar n\u00e5gon form av ljus, och kan d\u00e4rf\u00f6r endast uppt\u00e4ckas genom hur dess gravitation p\u00e5verkar galaxer och galaxhopar. \u00c4nnu mer mystisk \u00e4r m\u00f6rk energi, som tros alstra en sorts \u201cantigravitationskraft\u201d som f\u00e5r galaxerna i universum att r\u00f6ra sig ifr\u00e5n varandra allt snabbare.<\/p>\n

Euclid kommer att vara utrustad med ett teleskop med en diameter p\u00e5 1,2 m och tv\u00e5 vetenskapliga instrument. I sin bana 1,5 miljoner km fr\u00e5n jorden kommer den att kartl\u00e4gga 3D-f\u00f6rdelningen av upp till tv\u00e5 miljarder galaxer, utspridda \u00f6ver mer \u00e4n en tredjedel av hela himlavalvet. Genom att observera objekt som befinner sig upp till 10 miljarder ljus\u00e5r bort kommer den att blicka tillbaka i tiden f\u00f6r att avsl\u00f6ja hur universum har expanderat och f\u00f6r\u00e4ndrats under de senaste tre fj\u00e4rdedelarna av sin historia.<\/p>\n

Genom att anv\u00e4nda Euclid f\u00f6r att unders\u00f6ka hur m\u00f6rk materia och m\u00f6rk energi p\u00e5verkar galaxernas och galaxhoparnas r\u00f6relser och f\u00f6rdelning hoppas forskarna f\u00e5 en b\u00e4ttre f\u00f6rst\u00e5else f\u00f6r universums m\u00f6rkaste hemligheter.<\/p>","protected":false},"excerpt":{"rendered":"
