Mise Gaia agentury ESA dnes r\u00e1no odstartovala na raket\u011b Sojuz z evropsk\u00e9ho kosmodromu v Kourou ve Francouzsk\u00e9 Guyan\u011b, aby se vydala na vzru\u0161uj\u00edc\u00ed misi zam\u011b\u0159enou na studium miliardy slunc\u00ed.<\/p>\n<\/div>\n

Sonda Gaia bude opakovan\u011b prohled\u00e1vat oblohu a b\u011bhem p\u011bti let pozoruje ka\u017edou z miliardy hv\u011bzd v pr\u016fm\u011bru 70kr\u00e1t.

Pohyby hv\u011bzd lze \u2018p\u0159eto\u010dit zp\u011bt\u2019, abychom se dozv\u011bd\u011bli v\u00edce o tom, odkud poch\u00e1zej\u00ed a jak se Ml\u00e9\u010dn\u00e1 dr\u00e1ha v pr\u016fb\u011bhu miliard let formovala spojen\u00edm men\u0161\u00edch galaxi\u00ed, a \u2018p\u0159eto\u010dit vp\u0159ed\u2019, abychom se dozv\u011bd\u011bli v\u00edce o jej\u00edm kone\u010dn\u00e9m osudu.<\/p>\n
