Oran\u017eov\u00e9 pol\u00e1rne \u017eiary v Kanade<\/h1>\n

Ned\u00e1vna slne\u010dn\u00e1 b\u00farka zasiahla Zem a vytvorila nie\u010do, \u010do vyzeralo ako jasn\u00e9 st\u013apy tekvicovej farby tancuj\u00face na no\u010dnej oblohe nad Kanadou, odha\u013euje stra\u0161ideln\u00e1 nov\u00e1 fotografia. S obr\u00e1zkom je v\u0161ak probl\u00e9m: Oran\u017eov\u00e9 pol\u00e1rne \u017eiary by nemali existova\u0165. <\/p>\n

Namiesto nemo\u017en\u00fdch pol\u00e1rnych \u017eiaroviek sn\u00edmka v skuto\u010dnosti zachytila \u200b\u200bvz\u00e1cnu zmes \u010derven\u00fdch a zelen\u00fdch svetiel, ktor\u00e1 nebola tak\u00e1 vidite\u013en\u00e1, odkedy sa Zem pred 20 rokmi prehnala mon\u0161tru\u00f3znou halloweenskou slne\u010dnou b\u00farkou. <\/p>\n

\"N\u00e1padn\u00fd<\/p>\n

\u201eOran\u017eov\u00e1 bola \u00fa\u017easn\u00e1, priam neuverite\u013en\u00e1,\u201c povedal pre Spaceweather.com fotograf pol\u00e1rnej \u017eiary Harlan Thomas . “St\u013apy v strede tam zostali svieti\u0165 viac ako 20 min\u00fat.” Thomas zachytil farebn\u00fd z\u00e1ber 19. okt\u00f3bra nad rybn\u00edkom z\u00e1padne od Calgary v Alberte, asi tri dni po tom, \u010do Slnko spustilo mohutn\u00fd, pomaly sa pohybuj\u00faci v\u00fdron koron\u00e1lnej hmoty (CME) smerom k Zemi. <\/p>\n

Pol\u00e1rna \u017eiara sa vytv\u00e1ra, ke\u010f vysokoenergetick\u00e9 \u010dastice z CME alebo slne\u010dn\u00e9ho vetra obch\u00e1dzaj\u00fa magnetick\u00fd \u0161t\u00edt Zeme alebo magnetosf\u00e9ru a prehrievaj\u00fa molekuly plynu v hornej atmosf\u00e9re. Excitovan\u00e9 molekuly uvo\u013e\u0148uj\u00fa energiu vo forme svetla a farba tohto svetla z\u00e1vis\u00ed od toho, ktor\u00fd prvok je vzru\u0161en\u00fd. <\/p>\n

Dve najbe\u017enej\u0161ie farby pol\u00e1rnej \u017eiary s\u00fa \u010derven\u00e1 a zelen\u00e1, ktor\u00e9 s\u00fa obe vyd\u00e1van\u00e9 molekulami kysl\u00edka v r\u00f4znych nadmorsk\u00fdch v\u00fd\u0161kach (\u010derven\u00e9 pol\u00e1rne \u017eiary vznikaj\u00fa vo vy\u0161\u0161\u00edch nadmorsk\u00fdch v\u00fd\u0161kach ako ich zelen\u00e9 varianty). Ale ke\u010f slne\u010dn\u00e9 \u010dastice prenikn\u00fa hlboko do atmosf\u00e9ry, m\u00f4\u017eu tie\u017e spusti\u0165 vz\u00e1cne ru\u017eov\u00e9 pol\u00e1rne \u017eiary, ke\u010f excituj\u00fa molekuly dus\u00edka.<\/p>\n

Teoreticky m\u00f4\u017eu molekuly kysl\u00edka aj dus\u00edka za \u0161pecifick\u00fdch podmienok vyd\u00e1va\u0165 oran\u017eov\u00e9 vlnov\u00e9 d\u013a\u017eky. Av\u0161ak aj ke\u010f sa to stane, oran\u017eov\u00e1 je zahlten\u00e1 in\u00fdmi farbami, ktor\u00e9 vyd\u00e1vaj\u00fa molekuly, ktor\u00e9 ju obklopuj\u00fa, tak\u017ee je prakticky nemo\u017en\u00e9 vidie\u0165 tieto vlnov\u00e9 d\u013a\u017eky, informoval Spaceweather.com.<\/p>\n

Ako teda vid\u00edme t\u00fato farbu na najnov\u0161om obr\u00e1zku?<\/p>\n

“M\u00f4\u017ee d\u00f4js\u0165 k zmie\u0161aniu dvoch procesov [\u010dervenej a zelenej pol\u00e1rne \u017eiary], \u010do oklame kameru a oko, aby uverili, \u017ee je oran\u017eov\u00e1,” povedal Kjellmar Oksavik , vedec vesm\u00edrneho po\u010dasia a odborn\u00edk na pol\u00e1rnu \u017eiaru na univerzite v Bergene v N\u00f3rsku. Spaceweather.com. “V skuto\u010dnosti je \u010derven\u00e1 aj zelen\u00e1 z\u00e1rove\u0148.”<\/p>\n

Napriek tomu, \u017ee sa na oblohe \u010dasto vyskytuj\u00fa \u010derven\u00e9 a zelen\u00e9 pol\u00e1rne \u017eiary, \u201eoran\u017eov\u00e9\u201c pol\u00e1rne \u017eiary s\u00fa ve\u013emi zriedkav\u00e9.<\/p><\/blockquote>\n

Oran\u017eov\u00e1 farba je najviac vidite\u013en\u00e1 v strede ve\u013ek\u00fdch pol\u00e1rnych l\u00fa\u010dov – vertik\u00e1lnych st\u013apov svetla, ktor\u00e9 s\u00fa zarovnan\u00e9 pozd\u013a\u017e nevidite\u013en\u00fdch magnetick\u00fdch silo\u010diar – ktor\u00e9 sa skladaj\u00fa z \u010derven\u00e9ho aj zelen\u00e9ho svetla, ktor\u00e9 s\u00fa ve\u013emi nezvy\u010dajn\u00e9, povedal Oksavik.<\/p>\n

Naposledy boli tak\u00e9to \u017eiariv\u00e9 tekvicov\u00e9 odtiene zaznamenan\u00e9 po\u010das ve\u013ekej halloweenskej b\u00farky v roku 2003 \u2013 najsilnej\u0161ej slne\u010dnej b\u00farky v modern\u00fdch z\u00e1znamoch, informoval Spaceweather.com.
