\"\"Ji\u017e na prvn\u00ed pohled je patrn\u00e1 \u00fa\u017easn\u00e1 barevnost tohoto koutu vesm\u00edru. \u010cerven\u00e1 barva mlhoviny NGC 1499, zn\u00e1m\u00e9 pro sv\u016fj tvar pod jm\u00e9nem Kalifornie a nach\u00e1zej\u00edc\u00ed se v souhv\u011bzd\u00ed Persea, ost\u0159e kontrastuje s modr\u00fdmi Plej\u00e1dami, pono\u0159en\u00fdmi do hn\u011bdav\u00fdch prachov\u00fdch oblak. Barva mlhoviny je d\u016fsledkem rekombinace elektron\u016f s ionizovan\u00fdmi atomy vod\u00edku. Le\u017e\u00ed ve vzd\u00e1lenosti 1340 sv\u011bteln\u00fdch let od Zem\u011b a jej\u00ed skute\u010dn\u00fd rozm\u011br se odhaduje na 100 sv\u011bteln\u00fdch let. Na obloze zab\u00edr\u00e1 p\u0159ibli\u017en\u011b 7 \u00fapl\u0148k\u016f M\u011bs\u00edce a pravd\u011bpodobn\u011b je oza\u0159ov\u00e1na hv\u011bzdou \u03be Persei. Nach\u00e1z\u00ed se v galaktick\u00e9m spir\u00e1ln\u00edm rameni Oriona, v tom sam\u00e9m, ve kter\u00e9m bychom na\u0161li i na\u0161e Slunce spolu se Zem\u00ed a ostatn\u00edmi planetami a dal\u0161\u00edmi t\u011blesy. Mlhovina byla objevena a pops\u00e1na americk\u00fdm astronomem Edwardem Barnardem 3. listopadu 1885. Pr\u00e1v\u011b v\u010das, aby mohla b\u00fdt za\u0159azena do nov\u011b vznikaj\u00edc\u00edho Dreyerova katalogu NGC, tedy “Nov\u00e9ho gener\u00e1ln\u00edho katalogu” zahrnuj\u00edc\u00edho n\u011bkolik tis\u00edc mlhovin, galaxi\u00ed a hv\u011bzdokup.<\/p>\n

Druh\u00fdm objektem sn\u00edmku je v\u00fdrazn\u011b modr\u00e1 otev\u0159en\u00e1 hv\u011bzdokupa Plej\u00e1dy. Ta se ve vzd\u00e1lenosti 400 sv\u011bteln\u00fdch let od n\u00e1s prod\u00edr\u00e1 mra\u010dnem kosmick\u00e9ho prachu. To na sn\u00edmku m\u016f\u017eeme pozorovat v podob\u011b hn\u011bdo-\u010derno-\u010dervenav\u00fdch z\u00e1clon. I hv\u011bzdokupa Plej\u00e1dy, zvan\u00e1 t\u00e9\u017e Ku\u0159\u00e1tka s ofici\u00e1ln\u00edm ozna\u010den\u00edm M45, se nach\u00e1z\u00ed ve spir\u00e1ln\u00edm rameni Oriona. Ov\u0161em mnohem bl\u00ed\u017ee k n\u00e1m ne\u017e mlhovina Kalifornie. M\u016f\u017eeme v n\u00ed pouh\u00fdm okem podle stavu oblohy i na\u0161ich o\u010d\u00ed pozorovat 5 a\u017e 7, n\u011bkdy i v\u00edce nejjasn\u011bj\u0161\u00edch hv\u011bzd v podob\u011b malink\u00e9ho voz\u00ed\u010dku.

Tuto barvu zp\u016fsobuje rozptyl sv\u011btla jasn\u00fdch hv\u011bzd na prachov\u00fdch \u010d\u00e1stic\u00edch okoln\u00edho mra\u010dna. Ozna\u010den\u00ed M45 hv\u011bzdokup\u011b p\u0159i\u0159adil francouzsk\u00fd astronom Charles Messier, kdy\u017e 4. b\u0159ezna 1769 zm\u011b\u0159il jej\u00ed polohu a zanesl ji do sv\u00e9ho katalogu nekomet\u00e1rn\u00edch objekt\u016f na obloze. Messier byl toti\u017e velk\u00fdm pozorovatelem komet a tyto objekty jej \u010dasto p\u0159i pozorov\u00e1n\u00ed m\u00e1tly. Proto se rozhodl po\u0159\u00eddit jejich katalog, aby je v budoucnosti s kometami nezam\u011b\u0148oval.<\/p>\n

Na rozd\u00edl od mlhoviny Kalifornie, ze kter\u00e9 je mo\u017eno o\u010dima spat\u0159it pouze n\u00e1znak nejjasn\u011bj\u0161\u00ed \u010d\u00e1sti a to pouze za vynikaj\u00edc\u00edch pozorovac\u00edch podm\u00ednek, hv\u011bzdokupa Plej\u00e1dy je zn\u00e1m\u00e1 ji\u017e od starov\u011bku. Svou roli hr\u00e1la v mnoha kultur\u00e1ch. Nap\u0159\u00edklad indi\u00e1ni si na jej\u00edch hv\u011bzd\u00e1ch zkou\u0161eli sv\u016fj zrak, stejn\u011b jako sta\u0159\u00ed \u0158ekov\u00e9. Zd\u00e1 se, \u017ee svou roli Plej\u00e1dy hr\u00e1ly i u star\u00fdch Slovan\u016f. Pr\u00e1v\u011b od nich pravd\u011bpodobn\u011b poch\u00e1z\u00ed pojmenov\u00e1n\u00ed Ku\u0159\u00e1tka. V \u0159eck\u00e9 mytologii byly dcerami Atlanta a Pleione. Prvn\u00ed zn\u00e1m\u00e1 p\u00edsemn\u00e1 zm\u00ednka poch\u00e1z\u00ed od Hom\u00e9ra v jeho d\u00edlech Ilias a Odyssea. T\u0159ikr\u00e1t se objevuj\u00ed dokonce i v Bibli.<\/p>\n

Astrofotograf Ev\u017een Brunner n\u00e1m p\u0159inesl vskutku hezk\u00fd pohled do na\u0161eho vesm\u00edrn\u00e9ho okol\u00ed, t\u00e9m\u011b\u0159 za hv\u011bzdn\u00e1 humna.
