Jist\u011b si jej v \u0159\u00edjnu ka\u017ed\u00fd v\u0161iml.

Ano, planeta Mars, sv\u00edt\u00edc\u00ed na\u010dervenal\u00fdm poklidn\u00fdm sv\u011btlem, z\u00e1\u0159ila neoby\u010dejn\u011b jasn\u011b. A 14. \u0159\u00edjna dorazil a\u017e do \u201evelk\u00e9\u201c opozice, tedy do polohy v\u016f\u010di Zemi a Slunci, kdy jej nal\u00e9z\u00e1me p\u0159esn\u011b na opa\u010dn\u00e9 stran\u011b nebe ne\u017e Slunce.

\"\"Takov\u00e9to opozice byly v dob\u00e1ch ji\u017e d\u00e1vno minul\u00fdch v\u017edy p\u0159\u00edle\u017eitostmi, kdy astronomov\u00e9 mohli pom\u011brn\u011b detailn\u011b sledovat povrch Marsu. Nebyly ani kosmick\u00e9 sondy a zpo\u010d\u00e1tku ani fotografick\u00e9 emulze. A tak se pozorovatel\u00e9 u velk\u00fdch i mal\u00fdch dalekohled\u016f spol\u00e9hali na sv\u016fj zrak a kresbu, kterou po\u0159\u00eddili b\u011bhem pozorov\u00e1n\u00ed. A dokonce i v dob\u011b fotografick\u00e9 bylo oko schopno zachytit v\u011bt\u0161\u00ed detaily ne\u017e sn\u00edmek. Ov\u0161em schopnost mozku dom\u00fd\u0161let si chyb\u011bj\u00edc\u00ed detaily a fantazie pozorovatele mnohdy vedla a\u017e ke kuri\u00f3zn\u00edm interpretac\u00edm pozorov\u00e1n\u00ed, jako byly nap\u0159\u00edklad kdysi velmi popul\u00e1rn\u00ed \u201ekan\u00e1ly na Marsu\u201c.<\/p>\n

Planeta Mars je ov\u0161em zaj\u00edmav\u00e1 i bez velk\u00fdch opozic.

P\u0159edpokl\u00e1d\u00e1 se, \u017ee prvn\u00ed pozorov\u00e1n\u00ed t\u00e9to rud\u00e9 planety se uskute\u010dnila ji\u017e 3 a\u017e 4 tis\u00edce let p\u0159ed na\u0161\u00edm letopo\u010dtem. Znaly ji v\u0161echny starov\u011bk\u00e9 civilizace, jako putuj\u00edc\u00ed \u010dervenou hv\u011bzdu. Pr\u00e1v\u011b tato barva dala planet\u011b pon\u011bkud smutn\u00e9 ozna\u010den\u00ed planety z\u00e1niku, smrti a v\u00e1lek.

My v\u00e1m p\u0159in\u00e1\u0161\u00edme sn\u00edmek \u010desk\u00e9ho astrofotografa Jakuba Dobe\u0161e, kter\u00fd se v dob\u011b opozice pod\u00edval sv\u00fdm dalekohledem pr\u00e1v\u011b na planetu Mars. Vyu\u017eil chv\u00edle, kdy se jeho \u00fahlov\u00fd pr\u016fm\u011br na obloze p\u0159ibl\u00ed\u017eil 22\u201c a po\u0159\u00eddil sn\u00edmek planety. Ten po zpracov\u00e1n\u00ed zaslal do sout\u011b\u017ee \u010cesk\u00e1 astrofotografie m\u011bs\u00edce a jej\u00ed porota, kter\u00e1 funguje pod z\u00e1\u0161titou \u010cesk\u00e9 astronomick\u00e9 spole\u010dnosti, jej vybrala jako \u010desk\u00fd sn\u00edmek m\u011bs\u00edce \u0159\u00edjna roku 2020.<\/p>\n

Na sn\u00edmku n\u00e1s ov\u0161em sezn\u00e1mil nejen se samotnou planetou, ale i nap\u0159\u00edklad s nejv\u011bt\u0161\u00ed sopkou Slune\u010dn\u00ed soustavy Mons Olympus s v\u00fd\u0161kou 27 km nad nulovou v\u00fd\u0161kou Marsu. Na obr\u00e1zku je zobrazena jako sv\u011btl\u00e1 skvrna vlevo naho\u0159e. Je sice na Marsu nejvy\u0161\u0161\u00ed, ale i dal\u0161\u00ed sopky na sn\u00edmku (sm\u011brem k jeho st\u0159edu) jsou na zemsk\u00e9 pom\u011bry velmi vysok\u00e9, by\u0165 dosahuj\u00ed z marsovsk\u00e9ho hlediska pouh\u00fdch 18 kilometr\u016f. A tak bychom mohli po sn\u00edmku bloudit d\u00e1le a d\u00e1le, ale to ji\u017e nech\u00e1me na fanou\u0161c\u00edch astrofotografie a na z\u00e1v\u011br m\u016f\u017eeme Jakubovi Dobe\u0161ovi za tento \u00fa\u017easn\u00fd sn\u00edmek pod\u011bkovat.<\/p>\n
