Znanstveniki so do presenetljive ugotovitve pri\u0161li s tridimenzionalnim modeliranjem posnetkov, ki jih je v 20 letih zbral vesoljski teleskop Hubble, poro\u010da francoska tiskovna agencija AFP.<\/p>\n

Vpra\u0161anje, koliko galaksij je v vesolju, znanstvenike zaposluje, \u017ee odkar je ameri\u0161ki astronom Edwin Hubble leta 1924 ugotovil, da sosednja galaksija Andromeda ni del na\u0161e Rimske ceste.<\/p>\n

Vendar astronomi tudi z najsodobnej\u0161o opremo te\u017eko pridejo do natan\u010dnih podatkov. Ena od te\u017eav je, da je viden le del vesolja, od koder je svetloba, ki jo oddajajo oddaljeni objekti, prispela do Zemlje. Preostanek je zunaj na\u0161ega dosega.<\/p>\n

In \u0161e v tem vidnem delu vesolja trenutno dostopna tehnologija znanstvenikom omogo\u010da preu\u010devanje le desetine tega prostora. “Razburljivo je, da ve\u010d kot 90 odstotkov galaksij v vesolju \u0161e \u010daka na preu\u010ditev,” je dejal Christopher Conselice z univerze Nothingham, ki je vodil raziskavo. “Kdo ve, kaj zanimivega bomo odkrili, ko bomo te galaksije opazovali z naslednjo generacijo teleskopov,” je dodal.<\/p>\n

Znanstveniki pod vodstvom Conselica so Hubblove posnetke spremenili v tridimenzionalne modele, s katerimi so izmerili \u0161tevilo galaksij v razli\u010dnih obdobjih zgodovine vesolja. Analiza je segla ve\u010d kot 13 milijard let nazaj, to pa je zelo blizu velikega poka, s katerim naj bi nastalo vesolje.<\/p>\n

Astronomi so s pomo\u010djo novih matemati\u010dnih modelov pri\u0161li do \u0161tevila “nevidnih” galaksij, ki so zunaj dosega teleskopov, pri \u010demer so pri\u0161li do presenetljive ugotovitve, da jih je ve\u010dina pre\u0161ibkih ali preve\u010d oddaljenih, da bi jih lahko videli.<\/p>\n

Ko je bilo vesolje staro le nekaj milijard let, je bilo v njem desetkrat ve\u010d galaksij glede na obseg vesolja, kot jih je danes, so \u0161e ugotovili znanstveniki.<\/p>\n","protected":false},"excerpt":{"rendered":"
