ESA on andnud l\u00f5pliku rohelise tule Euclidile \u2013 p\u00f5nevale uuele missioonile, mille eesm\u00e4rk on uurida universumi varjuk\u00fclge. Kosmoselaev peaks startima 2020. aastal.<\/p>\n<\/div>\n

Euclid on saanud nime kuulsalt Kreeka matemaatikult, keda nimetatakse sageli \u201cgeomeetria isaks\u201d ja kes elas umbes 300 eKr. Selle missiooniks on otsida t\u00f5endeid n\u00e4htamatu tumeenergia ja tumeaine olemasolu kohta, mis moodustavad arvatavasti \u00fcle 95% universumi koostisest.<\/p>\n

Tumeaine on n\u00e4htamatu aine, mis ei kiirga ega neela mingit liiki valgust, mist\u00f5ttu on seda v\u00f5imalik tuvastada ainult selle j\u00e4rgi, kuidas selle gravitatsioon m\u00f5jutab galaktikaid ja galaktikaparvi. Veelgi salap\u00e4rasem on tumeenergia, mille puhul arvatakse, et see tekitab omamoodi \u201cantigravitatsiooni\u201d j\u00f5udu, mis paneb universumi galaktikad \u00fcksteisest \u00fcha kiiremini eemale liikuma.<\/p>\n

Euclid kannab pardal 1,2 m l\u00e4bim\u00f5\u00f5duga teleskoopi ja kahte teaduslikku instrumenti. Orbiidil, mis asub Maast 1,5 miljoni km kaugusel, kaardistab see kuni kahe miljardi galaktika 3D-jaotust, mis h\u00f5lmab enam kui kolmandikku kogu taevast. Vaadeldes objekte, mis asuvad kuni 10 miljardi valgusaasta kaugusel, vaatab satelliit ajas tagasi, et selgitada v\u00e4lja, kuidas universum on oma ajaloo viimase kolme neljandiku jooksul laienenud ja muutunud.<\/p>\n

Kasutades Euclidi, et uurida, kuidas tumeaine ja tumeenergia m\u00f5jutavad galaktikate ja galaktikaparvede liikumist ja jaotust, loodavad teadlased saada parema arusaama universumi k\u00f5ige salap\u00e4rasematest saladustest.<\/p>","protected":false},"excerpt":{"rendered":"
