Konjunkce Jupitera a Saturnu. Tedy okam\u017eik, kdy se k sob\u011b planety na obloze p\u0159ibl\u00ed\u017e\u00ed na nejmen\u0161\u00ed \u00fahlovou vzd\u00e1lenost. Vzhledem k tomu, \u017ee se planety pohybuj\u00ed ve velmi t\u011bsn\u00e9m rozmez\u00ed okolo ekliptiky, doch\u00e1z\u00ed k podobn\u00fdm setk\u00e1n\u00edm pom\u011brn\u011b \u010dasto. Tato konjunkce v\u0161ak byla pom\u011brn\u011b unik\u00e1tn\u00ed.<\/h6>\n

\"\"Plynn\u00ed planet\u00e1rn\u00ed ob\u0159i i se sv\u00fdmi m\u011bs\u00edci se k sob\u011b v prosinci roku 2020 na nebi p\u0159ibl\u00ed\u017eili natolik, \u017ee se ve\u0161li i do zorn\u00e9ho pole dalekohled\u016f a na obloze t\u00e9m\u011b\u0159 splynuli v jeden sv\u00edt\u00edc\u00ed \u201eobjekt\u201c. Takov\u00e9to t\u011bsn\u00e9 p\u0159ibl\u00ed\u017een\u00ed nastalo naposledy v roce 1623 a dal\u0161\u00ed n\u00e1s \u010dek\u00e1 a\u017e v roce 2080. Ov\u0161em konjunkce z roku 1623 byla obt\u00ed\u017en\u011b pozorovateln\u00e1, by\u0165 ji\u017e byl k dispozici astronomick\u00fd dalekohled. Planety se toti\u017e nach\u00e1zely na denn\u00ed obloze pobl\u00ed\u017e Slunce. A tak posledn\u00ed velmi t\u011bsn\u00e9 a dob\u0159e pozorovateln\u00e9 p\u0159ibl\u00ed\u017een\u00ed t\u011bchto planet nastalo v roce 1226. Tehdy v \u010cesk\u00e9m kr\u00e1lovstv\u00ed vl\u00e1dl kr\u00e1l P\u0159emysl Otakar I.<\/p>\n

Ov\u0161em ta nejzn\u00e1m\u011bj\u0161\u00ed konjunkce, dokonce t\u0159ikr\u00e1t se opakuj\u00edc\u00ed, nastala v roce 7 p\u0159ed na\u0161\u00edm letopo\u010dtem a byla s velkou pravd\u011bpodobnost\u00ed onou \u201eHv\u011bzdou Betl\u00e9mskou\u201c nad jesli\u010dkami.<\/p>\n

V prosinci 2020 se planety p\u0159ibl\u00ed\u017eily na vzd\u00e1lenost 6 obloukov\u00fdch minut. Pro v\u011bt\u0161inu pozorovatel\u016f ve st\u0159edn\u00ed Evrop\u011b se ale schov\u00e1valy za tu \u0159id\u0161\u00ed, tu hust\u0161\u00ed mraky. A tak astrofotografov\u00e9 vyj\u00ed\u017ed\u011bli do m\u00edst, kde se vytvo\u0159ily v oblac\u00edch d\u00edry, jimi\u017e bylo mo\u017eno jev pozorovat a fotografovat.<\/p>\n

U\u010dinil tak i slovensk\u00fd astrofotograf Martin Ba\u017eo, kter\u00fd svou fotografickou techniku vyvezl pod jasnou oblohu v Tatr\u00e1ch. Sn\u00edmek, respektive sn\u00edmky, po\u0159\u00eddil, zpracoval a v\u00fdslednou fotografii zaslal do sout\u011b\u017ee \u010cesk\u00e1 astrofotografie m\u011bs\u00edce. A v prosincov\u00e9m kole tuto sout\u011b\u017e vyhr\u00e1l.<\/p>\n

U spodn\u00edho okraje sn\u00edmku nalezneme planetu Jupiter. Ta je zn\u00e1m\u00e1 zejm\u00e9na ob\u0159\u00edm atmosf\u00e9rick\u00fdm v\u00edrem \u2013 Rudou skvrnou \u2013 podobn\u00fdm pozemsk\u00e9mu hurik\u00e1nu. Ov\u0161em jeho rozm\u011bry p\u0159esahuj\u00ed dvakr\u00e1t velikost planety Zem\u011b a i st\u00e1\u0159\u00ed Rud\u00e9 skvrny je obdivuhodn\u00e9. Vzhledem ke skute\u010dnosti, \u017ee ji pozorujeme ji\u017e od chv\u00edle, kdy ji lidstvo mohlo technicky zaznamenat, je jej\u00ed st\u00e1\u0159\u00ed minim\u00e1ln\u011b 300 let. Bohu\u017eel n\u00e1m ji sn\u00edmek neuk\u00e1\u017ee, nebo\u0165 v dob\u011b expozice byla t\u011bsn\u011b za v\u00fdchodn\u00edm obzorem planety.<\/p>\n

Planeta je obklopena tzv. Galileovsk\u00fdmi m\u011bs\u00edci. Vlevo Callisto a bl\u00ed\u017ee k planet\u011b Ganymed, vpravo pak Europa. M\u011bs\u00edc Io je mezi n\u00e1mi a kotou\u010dkem Jupitera a m\u00edsto n\u011bho tu\u0161\u00edme na povrchu planety jeho st\u00edn, pobl\u00ed\u017e st\u0159edu kotou\u010dku planety, pon\u011bkud v\u00fdchodn\u011b, tedy vlevo.<\/p>\n

I planetu Saturn nalezneme snadno podle prstenc\u016f, kter\u00e9 ji obklopuj\u00ed. Vpravo v rovin\u011b prstenc\u016f, d\u00e1le v\u0161ak od planety sv\u00edt\u00ed jej\u00ed nejjasn\u011bj\u0161\u00ed m\u011bs\u00edc Titan. Vlevo od planety pak nalezneme i velmi slab\u011b viditeln\u00e9 souputn\u00edky Dione, Thethys a Rheu (odspodu proti sm\u011bru hodinov\u00fdch ru\u010di\u010dek).<\/p>\n

Na z\u00e1v\u011br bychom r\u00e1di Martinovi Ba\u017eovi pod\u011bkovali za hezk\u00fd pohled nejen na konjunkci samotnou, ale i na sv\u011bt obou jasn\u00fdch planet a jejich m\u011bs\u00ed\u010dn\u00edch rodin. A to nejen za porotce sout\u011b\u017ee, kterou za\u0161ti\u0165uje \u010cesk\u00e1 astronomick\u00e1 spole\u010dnost, ale jist\u011b i za ostatn\u00ed astronomy a milovn\u00edky oblohy. A p\u0159ejeme hodn\u011b podobn\u00fdch sn\u00edmk\u016f<\/p>\n
