Uplynuly ji\u017e stovky let od doby, kdy Kry\u0161tof Kolumbus obeplul Zemi a objevil nov\u00e9 sv\u011bty \u2013 ale nenechte si od nikoho namluvit, \u017ee \u00e9ra velk\u00fdch objev\u016f skon\u010dila. Vesm\u00edr je obrovsk\u00fd a pln\u00fd tajemstv\u00ed, kter\u00e1 \u010dekaj\u00ed na odhalen\u00ed, jako nap\u0159\u00edklad sv\u011bt komety 67P\/\u010curymov-Gerasimenko, kterou v sou\u010dasn\u00e9 dob\u011b zkoum\u00e1 sonda Rosetta.<\/p>\n<\/div>\n

Od sv\u00e9ho p\u0159\u00edletu ke komet\u011b v srpnu lo\u0148sk\u00e9ho roku sonda Rosetta prozkoumala v\u00edce ne\u017e dv\u011b t\u0159etiny povrchu komety a ten se uk\u00e1zal b\u00fdt zaj\u00edmav\u011bj\u0161\u00ed, ne\u017e se o\u010dek\u00e1valo. Krajina p\u0159edstavuje vzru\u0161uj\u00edc\u00ed sm\u011bsici \u2013 n\u011bkter\u00e9 oblasti jsou pokryty hust\u00fdm prachem, jin\u00e9 se vyzna\u010duj\u00ed skalnat\u00fdmi \u00fatesy a ka\u0148ony. V dal\u0161\u00edch oblastech se nach\u00e1zej\u00ed obrovsk\u00e9 p\u0159\u00edkopy, j\u00e1my a balvany nebo hladk\u00e9 pou\u0161t\u011b.<\/p>\n

Mnoh\u00e9 z p\u0159\u00edkr\u00fdch \u00fates\u016f na Rosett\u011b pokr\u00fdvaj\u00ed nebezpe\u010dn\u011b vypadaj\u00edc\u00ed trhliny. Nejv\u011bt\u0161\u00ed trhlina m\u011b\u0159\u00ed 500 metr\u016f \u2013 to je jako p\u011bt fotbalov\u00fdch h\u0159i\u0161\u0165!<\/p>\n

Dal\u0161\u00edm zaj\u00edmav\u00fdm jevem jsou proudy, kter\u00e9 byly pozorov\u00e1ny, jak stoupaj\u00ed z prohlubn\u00ed roztrou\u0161en\u00fdch po povrchu komety. Plyn unikaj\u00edc\u00ed z t\u011bchto proud\u016f p\u016fsob\u00ed podobn\u011b jako v\u00edtr na Zemi a rozv\u00ed\u0159\u00ed prach na povrchu. To n\u011bkdy vytv\u00e1\u0159\u00ed vlnky na povrchu, podobn\u00e9 t\u011bm, kter\u00e9 lze ob\u010das vid\u011bt na pl\u00e1\u017ei p\u0159i odlivu.<\/p>\n

Za t\u011bch n\u011bkolik m\u011bs\u00edc\u016f, co sonda Rosetta doprov\u00e1z\u00ed kometu, jsme se ji\u017e dozv\u011bd\u011bli opravdu mnoho. Vzhledem k tomu, \u017ee Rosetta bude v p\u0159\u00ed\u0161t\u00edm roce shroma\u017e\u010fovat st\u00e1le v\u00edce dat, jsou v\u011bdci p\u0159esv\u011bd\u010deni, \u017ee se jim kone\u010dn\u011b poda\u0159\u00ed odpov\u011bd\u011bt na n\u011bkter\u00e9 d\u016fle\u017eit\u00e9 ot\u00e1zky t\u00fdkaj\u00edc\u00ed se vzniku na\u0161\u00ed slune\u010dn\u00ed soustavy!<\/p>\n
