Raketa Sojuz bo 2-tonski vesoljski observatorij, znan pod imenom Gaia, poslala 1,5 milijona kilometrov stran od Zemlje. Od tam bo naslednjih pet let izvajal popis pribli\u017eno ene milijarde zvezd v na\u0161i galaksiji, Mle\u010dni cesti.<\/p>\n<\/div>\n<p>Gaia bo poslala nazaj najnatan\u010dnej\u0161e podatke, ki so bili kdaj koli pridobljeni o polo\u017eajih, gibanju in svetlosti teh zvezd. Vsaka od izbranih zvezd bo med petletno misijo opazovana pribli\u017eno 70-krat. To pomeni povpre\u010dno 40 milijonov opazovanj na dan! Polo\u017eaji svetlej\u0161ih objektov (ki so \u0161e vedno 4.000-krat \u0161ibkej\u0161i od tistih, ki jih lahko vidimo s prostim o\u010desom) bodo dolo\u010deni z natan\u010dnostjo, primerljivo z merjenjem \u0161irine \u010dlove\u0161kega lasu z razdalje 1.000 km.<\/p>\n<p>Da bi dosegla to izjemno natan\u010dnost, je Gaia opremljena z izjemno ob\u010dutljivim \u201co\u010desom\u201d \u2013 najve\u010djo digitalno kamero, ki je kdaj koli letela v vesolju. To bo Gaii omogo\u010dilo zaznavanje objektov, ki so milijonkrat \u0161ibkej\u0161i od tistih, ki jih lahko vidimo s prostim o\u010desom. Opremljena je tudi z dvema opti\u010dnima teleskopoma in tremi znanstvenimi instrumenti ter 10 metrov \u0161irokim \u201ckrilom\u201d, ki deluje kot son\u010dni \u0161\u010dit in proizvaja son\u010dno energijo.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1500\" data-credit=\"ESA\/Herschel\/PACS\/SPIRE\/J.Fritz, U.Gent\/XMM-Newton\/EPIC\/W.
