Leo I je trpasli\u010dia sf\u00e9roid\u00e1lna galaxia, ktor\u00e1 patr\u00ed medzi satelitn\u00e9 galaxie Mlie\u010dnej cesty. Nach\u00e1dza sa v s\u00fahvezd\u00ed Leva, len necel\u00fdch 12 uhlov\u00fdch min\u00fat od jasnej hviezdy Regulus \u2013 preto sa jej niekedy hovor\u00ed aj Regulus Dwarf. Od Zeme je vzdialen\u00e1 pribli\u017ene 820 000 sveteln\u00fdch rokov, \u010do z nej rob\u00ed jednu z najvzdialenej\u0161\u00edch zn\u00e1mych satelitn\u00fdch galaxi\u00ed Mlie\u010dnej cesty.<\/p>\n\n\n\n

Objavil ju v roku 1950 americk\u00fd astron\u00f3m Albert George Wilson, a to na fotografick\u00fdch dosk\u00e1ch vznikaj\u00facich v r\u00e1mci prehliadky oblohy National Geographic Society \u2013 Palomar Observatory Sky Survey, sn\u00edman\u00fdch 48-palcov\u00fdm Schmidtov\u00fdm \u010falekoh\u013eadom na observat\u00f3riu Palomar.<\/p>\n\n\n\n

Leo I m\u00e1 ve\u013emi n\u00edzky povrchov\u00fd jas, tak\u017ee aj napriek pomerne ve\u013ek\u00e9mu uhlov\u00e9mu priemeru ju amat\u00e9rske \u010falekoh\u013eady zachytia len \u0165a\u017eko a vy\u017eaduje si tmav\u00fa oblohu. Bl\u00edzkos\u0165 \u017eiariv\u00e9ho Regulu rob\u00ed z galaxie jeden z pozorovate\u013esky najn\u00e1ro\u010dnej\u0161\u00edch objektov Miestnej skupiny galaxi\u00ed, ke\u010f\u017ee jej svetlo v \u017eiare hviezdy takmer zanik\u00e1. Zauj\u00edmav\u00e1 je aj jej hist\u00f3ria tvorby hviezd \u2013 v\u00e4\u010d\u0161ina hviezd v nej vznikla v obdob\u00ed pred pribli\u017ene 6 a\u017e 2 miliardami rokov, pri\u010dom tvorba nov\u00fdch hviezd sa v\u00fdrazne spomalila a\u017e asi pred miliardou rokov. V\u010faka tomu patr\u00ed medzi \u201enajmlad\u0161ie\u201c trpasli\u010die sf\u00e9roid\u00e1lne satelity Mlie\u010dnej cesty. Galaxia m\u00e1 tie\u017e jednu z najvy\u0161\u0161\u00edch nameran\u00fdch hust\u00f4t tmavej hmoty spomedzi klasick\u00fdch trpasli\u010d\u00edch sf\u00e9roid\u00e1lnych galaxi\u00ed a niektor\u00e9 \u0161t\u00fadie v jej strede nazna\u010duj\u00fa pr\u00edtomnos\u0165 mas\u00edvnej \u010diernej diery, hoci t\u00e1to ot\u00e1zka zatia\u013e nie je definit\u00edvne uzavret\u00e1.<\/p>\n\n\n\n

Galaxiu som fotil na \u010falekoh\u013eade Sky-Watcher Quattro 150P s kamerou SVBony SV605MC na mont\u00e1\u017ei Sky-Watcher HEQ5 PRO, cez LRGB filtre. Na v\u00fdsledn\u00fa fotografiu som str\u00e1vil spolu 25 hod\u00edn a 30 min\u00fat expoz\u00edcie.<\/p>\n\n\n\n
