Existuje na Marsu \u017eivot? Jist\u011b, nikdo nepo\u010d\u00edt\u00e1 s t\u00edm, \u017ee by se tam na\u0161li inteligentn\u00ed Mar\u0165an\u00e9, jako ti, kter\u00e9 zn\u00e1me z filmu \u2018V\u00e1lka sv\u011bt\u016f\u2019. V\u00fdsledky z dru\u017eice Mars Express agentury ESA a pozemn\u00edch observato\u0159\u00ed v\u0161ak nazna\u010duj\u00ed, \u017ee se v podzem\u00ed rud\u00e9 planety mohou skr\u00fdvat jednoduch\u00e9 formy \u017eivota.<\/p>\n<\/div>\n

Kl\u00ed\u010dem k tomuto z\u00e1hadn\u00e9mu jevu je metan, plyn, kter\u00fd se na Zemi pou\u017e\u00edv\u00e1 k va\u0159en\u00ed a vyt\u00e1p\u011bn\u00ed. Velk\u00e1 \u010d\u00e1st metanu v na\u0161\u00ed atmosf\u00e9\u0159e poch\u00e1z\u00ed z vysp\u011bl\u00fdch forem \u017eivota, nap\u0159\u00edklad z tr\u00e1ven\u00ed potravy u skotu. Existuj\u00ed v\u0161ak i jin\u00e9 zp\u016fsoby vzniku metanu, nap\u0159\u00edklad sope\u010dn\u00e1 \u010dinnost.<\/p>\n

Metan byl na Marsu objeven v roce 2003. Vzhledem k tomu, \u017ee se tento plyn snadno rozkl\u00e1d\u00e1, p\u0159edpokl\u00e1dala se jeho \u017eivotnost v mar\u0165ansk\u00e9 atmosf\u00e9\u0159e na p\u0159ibli\u017en\u011b 300 let. Podrobn\u011bj\u0161\u00ed anal\u00fdza uk\u00e1zala, \u017ee metan se ve skute\u010dnosti soust\u0159edil ve t\u0159ech oblastech. To nazna\u010dovalo, \u017ee se uvol\u0148oval pr\u00e1v\u011b v dan\u00e9m okam\u017eiku a \u017ee jsme jej detekovali je\u0161t\u011b p\u0159edt\u00edm, ne\u017e se sta\u010dil roz\u0161\u00ed\u0159it po cel\u00e9 planet\u011b.<\/p>\n

Pak Mars p\u0159ichystal dal\u0161\u00ed p\u0159ekvapen\u00ed. M\u00edsto toho, aby metan mizel 300 let, na po\u010d\u00e1tku roku 2006 t\u00e9m\u011b\u0159 \u00fapln\u011b zmizel. N\u011bco ho z atmosf\u00e9ry odstra\u0148ovalo 600kr\u00e1t rychleji, ne\u017e se o\u010dek\u00e1valo. V\u011bdci z ESA maj\u00ed podez\u0159en\u00ed, \u017ee za t\u00edm m\u016f\u017ee b\u00fdt povrch planety. Bu\u010f se metan zachycuje v prachu, nebo ho ni\u010d\u00ed vysoce reaktivn\u00ed chemik\u00e1lie, jako je peroxid vod\u00edku. To by mohlo znamenat, \u017ee povrch je pro \u017eivot mnohem nep\u0159\u00e1tel\u0161t\u011bj\u0161\u00ed, ne\u017e se dosud p\u0159edpokl\u00e1dalo. Pokud je tomu tak, budou budouc\u00ed pr\u016fzkumn\u00edci muset vrtat hluboko pod povrch, aby hledali stopy minul\u00e9ho \u010di sou\u010dasn\u00e9ho \u017eivota.<\/p>","protected":false},"excerpt":{"rendered":"
