Mezin\u00e1rodn\u00ed kosmick\u00e1 stanice (ISS) se stala vlastn\u011b u\u017e b\u011b\u017enou sou\u010d\u00e1st\u00ed na\u0161eho \u017eivota.

Tyto p\u0159elety dok\u00e1\u017eeme velmi p\u0159esn\u011b spo\u010d\u00edtat, dokonce bychom si podle n\u00ed mohli t\u00e9m\u011b\u0159 \u0159\u00eddit i hodinky.<\/h6>\n

\"\"Informace o p\u0159eletech ISS nalezneme bez probl\u00e9m\u016f na internetu. O jej\u00ed vybudov\u00e1n\u00ed na ob\u011b\u017en\u00e9 dr\u00e1ze Zem\u011b se zaslou\u017eilo hned n\u011bkolik zem\u00ed, nu je opravdu \u201emezin\u00e1rodn\u00ed\u201c. Ov\u0161em hlavn\u00ed slovo maj\u00ed Rusko a USA. Ostatn\u011b kosmonauti, kte\u0159\u00ed se na ISS v \u0161esti\u010dlenn\u00fdch pos\u00e1dk\u00e1ch st\u0159\u00eddaj\u00ed v p\u016flro\u010dn\u00edch intervalech, se mus\u00ed domluvit anglicky a rusky.<\/p>\n

I kdy\u017e stanici pouh\u00fdma o\u010dima vid\u00edme jako pomalu se sunouc\u00ed \u201ehv\u011bzdu\u201c a vn\u00edm\u00e1me tak pouze jej\u00ed jasnost, tedy vlastn\u011b intenzitu slune\u010dn\u00edho sv\u011btla odr\u00e1\u017eej\u00edc\u00edho se od modul\u016f a slune\u010dn\u00edch panel\u016f, mus\u00edme si uv\u011bdomit, \u017ee stanice je opravdu pom\u011brn\u011b velik\u00e1. Ostatn\u011b, kdybychom si ji mohli polo\u017eit na standardn\u00ed fotbalov\u00e9 h\u0159i\u0161t\u011b, o n\u011bco by jej dokonce p\u0159esahovala. O skute\u010dn\u00e9 velikosti stanice se m\u016f\u017eeme p\u0159esv\u011bd\u010dit t\u0159eba i d\u00edky v\u00edt\u011bzn\u00e9mu sn\u00edmku sout\u011b\u017ee \u201e\u010cesk\u00e1 astrofotografie m\u011bs\u00edce\u201c, kterou za\u0161ti\u0165uje \u201e\u010cesk\u00e1 astronomick\u00e1 spole\u010dnost\u201c. Jeho autorem je astrofotograf Libor Ha\u0161pl.<\/p>\n

Ten vyu\u017eil chv\u00edle, kdy se stanice pohybovala na denn\u00ed obloze a pro pozorovatele nedaleko m\u011bsta Kol\u00edn se jej\u00ed dr\u00e1ha prom\u00edtla na pozad\u00ed Slunce. Cel\u00fd p\u0159elet p\u0159es slune\u010dn\u00ed disk ve specializovan\u00e9m astronomick\u00e9m dalekohledu trval pouh\u00fdch 0,68 sekundy. I tak se autorovi poda\u0159ilo zachytit 26 individu\u00e1ln\u00edch \u201eportr\u00e9t\u016f\u201c kosmick\u00e9 stanice na pozad\u00ed na\u0161\u00ed nejbli\u017e\u0161\u00ed hv\u011bzdy, Slunce. To je ov\u0161em mnohem v\u011bt\u0161\u00ed ne\u017e stanice. Jeho pr\u016fm\u011br je 1 392 020 km a do jeho pr\u016fm\u011bru by se tak ve\u0161lo asi 109 Zem\u00ed. Je v\u0161ak vzd\u00e1leno od na\u0161\u00ed Zem\u011b t\u00e9m\u011b\u0159 150 mili\u00f3n\u016f kilometr\u016f. Stanice sama m\u00e1 rozm\u011bry 51 x 109 x 27 metr\u016f, ob\u00edh\u00e1 v\u0161ak Zemi ve v\u00fd\u0161ce \u201epouh\u00fdch\u201c 400 km. I proto se n\u00e1m na pozad\u00ed na\u0161eho Slunce zd\u00e1 tak velik\u00e1. Dokonce tak, \u017ee jsme schopni i pom\u011brn\u011b mal\u00fdm dalekohledem zachytit nejen syst\u00e9m obrovsk\u00fdch slune\u010dn\u00edch panel\u016f, ale i n\u011bkter\u00e9 moduly, ze kter\u00fdch je stanice slo\u017een\u00e1. Ve chv\u00edli expozice byla stanice od pozorovatele vzd\u00e1lena 526 km, nem\u011bl ji toti\u017e p\u0159\u00edmo nad hlavou.<\/p>\n

Krom\u011b stanice samotn\u00e9 na sn\u00edmku vid\u00edme samoz\u0159ejm\u011b i Slunce. Autor pou\u017eil teleskop, kter\u00fd odfiltruje ze slune\u010dn\u00edho sv\u011btla v\u0161echny \u201enepot\u0159ebn\u00e9\u201c slo\u017eky a ponech\u00e1 pouze z\u00e1\u0159en\u00ed vych\u00e1zej\u00edc\u00ed ze spektr\u00e1ln\u00ed \u010d\u00e1ry H-alfa. To je vyz\u00e1\u0159eno b\u011bhem p\u0159echodu elektronu v atomu vod\u00edku z jeho t\u0159et\u00ed na druhou hladinu, p\u0159i\u010dem\u017e se vyprodukuje energie 1,89 eV na vlnov\u00e9 d\u00e9lce 656 nm. My t\u00e9to \u010d\u00e1\u0159e \u0159\u00edk\u00e1me prvn\u00ed linie Balmerovy s\u00e9rie \u010dar atom\u00e1rn\u00edho vod\u00edku.<\/p>\n

Pro n\u00e1s je toto \u010derven\u00e9 z\u00e1\u0159en\u00ed zaj\u00edmav\u00e9 zejm\u00e9na t\u00edm, \u017ee v n\u011bm m\u016f\u017eeme sledovat nap\u0159\u00edklad kr\u00e1sn\u00e9 protuberance. Ty na sn\u00edmku vid\u00edme nad okrajem Slunce a p\u0159edstavuj\u00ed chladn\u011bj\u0161\u00ed vod\u00edkov\u00e1 oblaka formovan\u00e1 magnetick\u00fdm polem Slunce. D\u00e1le bychom mohli p\u0159i velk\u00e9 d\u00e1vce \u0161t\u011bst\u00ed vid\u011bt i vzplanut\u00ed slune\u010dn\u00ed erupce, ov\u0161em v dob\u011b slune\u010dn\u00edho minima, jak\u00e9 nyn\u00ed pro\u017e\u00edv\u00e1me, by to bylo skute\u010dn\u011b velk\u00e9 \u0161t\u011bst\u00ed.<\/p>\n

Na z\u00e1v\u011br se n\u00e1m sem ji\u017e vejde pouze velk\u00e9 pod\u011bkov\u00e1n\u00ed Liboru Ha\u0161plovi na netradi\u010dn\u00ed pohled na Slunce i kosmickou stanici ISS. Gratulujeme ke kr\u00e1sn\u00e9mu sn\u00edmku.<\/p>\n
