Slzy svat\u00e9ho Vav\u0159ince. Pravd\u011bpodobn\u011b jste toto pojmenov\u00e1n\u00ed n\u011bkdy sly\u0161eli. Kdo byl svat\u00fd Vav\u0159inec a pro\u010d o n\u011bm p\u00ed\u0161eme v tomto textu?<\/h6>\n

\"\"Ka\u017ed\u00fd rok, okolo 12. srpna, nast\u00e1v\u00e1 maximum meteorick\u00e9ho roje Perseid. Pozorujeme tak sv\u011bteln\u00e9 jevy v zemsk\u00e9 atmosf\u00e9\u0159e, kter\u00e9 p\u0159edstavuj\u00ed vlastn\u011b z\u00e1nik \u010d\u00e1stic komet\u00e1rn\u00edho materi\u00e1lu, se kter\u00fdm se na\u0161e Zem\u011b na dr\u00e1ze kolem Slunce potk\u00e1v\u00e1. V tomto p\u0159\u00edpad\u011b se jedn\u00e1 o drobn\u00e9 \u010d\u00e1stice, kter\u00e9 se postupn\u011b uvol\u0148uj\u00ed z komety 109P\/Swift-Tuttle. Ta se na sv\u00e9 cest\u011b okolo Slunce, kter\u00e1 j\u00ed trv\u00e1 v\u00edce ne\u017e 133 let, v\u017edy pobl\u00ed\u017e p\u0159\u00edslun\u00ed zah\u0159\u00edv\u00e1 a uvol\u0148uje postupn\u011b plyn i \u010d\u00e1sti pevn\u00e9ho materi\u00e1lu. Proto\u017ee se tato kometa ke Slunci vrac\u00ed ji\u017e velmi dlouho, uvoln\u011bn\u00fd materi\u00e1l se stihl rozprost\u0159\u00edt pod\u00e9l cel\u00e9 jej\u00ed dr\u00e1hy a my se s n\u00edm ve v\u011bt\u0161\u00edm \u010di men\u0161\u00edm mno\u017estv\u00ed setk\u00e1v\u00e1me rok co rok, pr\u00e1v\u011b v\u017edy zhruba v polovin\u011b srpna. Intenzita roje, tedy mno\u017estv\u00ed jasn\u00fdch jev\u016f na obloze \u2013 meteor\u016f – z\u00e1vis\u00ed na \u010dasov\u00e9 vzd\u00e1lenosti toho kter\u00e9ho roku od pr\u016fchodu komety p\u0159\u00edslun\u00edm. To posledn\u00ed nastalo v prosinci roku 1992 a tak v letech 1992 a 1993 bylo mo\u017eno pozorovat a\u017e 300 meteor\u016f za hodinu. Letos jich bylo kolem 100.<\/p>\n

S meteory tohoto roje se setk\u00e1vali i na\u0161i p\u0159edkov\u00e9. Patrn\u011b prvn\u00ed zpr\u00e1vy m\u00e1me z roku 36 z \u010c\u00edny, dal\u0161\u00ed n\u00e1sledovaly z Japonska a Koreje. Prvn\u00ed zaznamenan\u00e9 pozorov\u00e1n\u00ed v Evrop\u011b se datuje do roku 811. Mezi 12. a 19. stolet\u00edm je z\u00e1znam\u016f o pozorov\u00e1n\u00ed roje pom\u011brn\u011b m\u00e1lo. V roce 1861 upozornil italsk\u00fd astronom Giovanni Schiaparelli na podobnost drah meteor\u016f roje Perseid a komety 109P\/Swift-Tuttle.<\/p>\n

A co tedy ten svat\u00fd Vav\u0159inec? Jedn\u00e1 se o \u0159\u00edmsk\u00e9ho klerika, kter\u00fd byl 10. srpna roku 258 v \u0158\u00edm\u011b za\u017eiva upe\u010den p\u0159i pron\u00e1sledov\u00e1n\u00ed k\u0159es\u0165an\u016f \u0159\u00edmsk\u00fdm c\u00edsa\u0159em Valerianem. Nevydal toti\u017e po smrti umu\u010den\u00e9ho pape\u017ee Sixta II. c\u00edsa\u0159i c\u00edrkevn\u00ed majetek a rad\u011bji jej rozdal chud\u00fdm. Proto\u017ee se datum jeho smrti pom\u011brn\u011b p\u0159esn\u011b shoduje s maximem Perseid, \u0159\u00edk\u00e1me jim \u010dasto slzy svat\u00e9ho Vav\u0159ince.<\/p>\n

Jejich leto\u0161n\u00ed portr\u00e9t do sout\u011b\u017ee \u010cesk\u00e1 astrofotografie m\u011bs\u00edce zaslal Robert Barsa ze Slovenska. Krom\u011b hv\u011bzdn\u00e9ho pozad\u00ed na n\u011bm vid\u00edme i 87 jasn\u00fdch meteor\u016f, kter\u00e9 byly zachyceny b\u011bhem n\u011bkolika noc\u00ed od 9. do 13. srpna 2020. Ty byly vlo\u017eeny do v\u00fdsledn\u00e9 kompozice a ilustruj\u00ed jejich dr\u00e1hy po nebi tak, \u017ee zd\u00e1nliv\u011b vyl\u00e9taj\u00ed z jednoho m\u00edsta oblohy. A proto\u017ee se toto m\u00edsto, kter\u00e9mu \u0159\u00edk\u00e1me radiant, nach\u00e1z\u00ed v souhv\u011bzd\u00ed Persea, \u0159\u00edk\u00e1me jim Perseidy.<\/p>\n

Proto\u017ee se jedn\u00e1 o st\u00e1le je\u0161t\u011b pom\u011brn\u011b bohat\u00fd roj, po\u0159\u00e1daj\u00ed se na jeho pozorov\u00e1n\u00ed r\u016fzn\u00e9 pozorovac\u00ed kampan\u011b \u010di expedice. B\u011bhem t\u00e9to v\u00fdpravy se autorovi poda\u0159ilo zachytit nejen velk\u00e9 mno\u017estv\u00ed meteor\u016f a p\u0159ekr\u00e1sn\u00fd obraz Ml\u00e9\u010dn\u00e9 dr\u00e1hy, vz\u00e1jemn\u011b se prol\u00ednaj\u00edc\u00ed spir\u00e1ln\u00ed ramena na\u0161\u00ed Galaxie, ale i dal\u0161\u00ed objekty a jevy. Tak p\u0159edn\u011b jsou to jasn\u00e9 planety Jupiter a Saturn. Jist\u011b je nep\u0159ehl\u00e9dneme, nebo\u0165 zejm\u00e9na Jupiter je nejjasn\u011bj\u0161\u00edm objektem, kter\u00fd na zobrazen\u00e9 obloze spat\u0159\u00edme. A Saturn se nach\u00e1z\u00ed jen nedaleko. Na prvn\u00ed pohled zaujmou i n\u011bkter\u00e1 souhv\u011bzd\u00ed a jasn\u00e9 hv\u011bzdy. T\u00e9m\u011b\u0159 v zenitu sv\u00edt\u00ed mod\u0159e hv\u011bzda Vega, nejjasn\u011bj\u0161\u00ed ze souhv\u011bzd\u00ed Lyry.

V neposledn\u00ed \u0159ad\u011b spat\u0159\u00edme zejm\u00e9na nad obzorem sv\u011bteln\u00e9 zne\u010di\u0161t\u011bn\u00ed a dokonce i samotn\u00e9 astronomy a jejich dalekohledy, pod na\u010dervenal\u00fdm p\u0159\u00edsvitem orienta\u010dn\u00edch baterek.<\/p>\n
