Misija Gaia Evropske vesoljske agencije (ESA) je danes zjutraj poletela z raketo Sojuz iz evropskega vesoljskega izstrelitvenega centra v Kourouju v Francoski Gvajani na svojo vznemirljivo misijo, katere cilj je raziskovanje milijarde zvezd.<\/p>\n<\/div>\n

Gaia bo izdelala doslej najnatan\u010dnej\u0161i zemljevid Mle\u010dne ceste. Z natan\u010dnimi meritvami polo\u017eajev in gibanj milijarde zvezd bo odgovorila na vpra\u0161anja o nastanku in razvoju na\u0161e galaksije.<\/p>\n

Gaia je zdaj na poti proti orbiti okoli virtualne to\u010dke v vesolju, imenovane L2, ki je z vidika Sonca pribli\u017eno 1,5 milijona kilometrov oddaljena od Zemlje.<\/p>\n

Gaia bo z ve\u010dkratnim pregledovanjem neba v petih letih vsako od milijarde zvezd opazovala povpre\u010dno 70-krat. Merila bo polo\u017eaj in klju\u010dne fizikalne lastnosti vsake zvezde, vklju\u010dno z njeno svetlostjo, temperaturo in kemijsko sestavo.<\/p>\n

Gibanje zvezd lahko \u2018prevrnemo nazaj\u2019, da bi bolje razumeli, od kod izvirajo in kako se je Mle\u010dna pot v milijardah let oblikovala iz zdru\u017eevanja manj\u0161ih galaksij, ter ga \u2018pospe\u0161imo\u2019, da bi bolje razumeli njeno kon\u010dno usodo.<\/p>\n

S primerjavo ponavljajo\u010dih se pregledov neba bo Gaia odkrila tudi ve\u010d deset tiso\u010d supernov \u2013 smrtnih krikov zvezd, ki ob koncu svojega \u017eivljenja eksplodirajo. Rahla periodi\u010dna nihanja v polo\u017eajih nekaterih zvezd pa naj bi razkrila prisotnost planetov, ki kro\u017eijo okoli njih, saj te zvezde vle\u010dejo sem in tja.<\/p>\n

Gaia bo odkrila tudi nove asteroide v na\u0161em Oson\u010dju in natan\u010dneje dolo\u010dila tirnice \u017ee znanih, hkrati pa bo izvedla natan\u010dne preizkuse Einsteinove slavne splo\u0161ne teorije relativnosti.<\/p>","protected":false},"excerpt":{"rendered":"
