Tento objev, kter\u00fd u\u010dinila sonda Philae, vzbudil nad\u0161en\u00ed mezi v\u011bdci, kte\u0159\u00ed se domn\u00edvaj\u00ed, \u017ee komety mohly hr\u00e1t z\u00e1sadn\u00ed roli v zaset\u00ed Zem\u011b organick\u00fdm materi\u00e1lem nezbytn\u00fdm pro vznik \u017eivota.<\/p>\n\n
V srpnu detekovala sonda Rosetta, kter\u00e1 vynesla Philae ke komet\u011b, n\u011bkolik organick\u00fdch molekul v plynn\u00e9m chvostu komety, v\u010detn\u011b vody, oxidu uhelnat\u00e9ho, oxidu uhli\u010dit\u00e9ho, amoniaku, metanu a metanolu. Toto je v\u0161ak poprv\u00e9, co v\u011bdci dok\u00e1zali p\u0159\u00edmo odebrat vzorky z komety a zkoumat p\u0159\u00edtomnost komplexn\u00edch organick\u00fdch slou\u010denin.<\/p>\n\n
Studiem toho, kter\u00e9 molekuly jsou p\u0159\u00edtomny v atmosf\u00e9\u0159e komety, a pokusem ur\u010dit, jak vznikly, mohou v\u011bdci potenci\u00e1ln\u011b z\u00edskat poznatky o historii \u017eivota na Zemi. Organick\u00e9 molekuly jsou nezbytn\u00e9 pro \u017eivot, jak ho zn\u00e1me, a jejich p\u0159\u00edtomnost na komet\u00e1ch nazna\u010duje, \u017ee tato nebesk\u00e1 t\u011blesa mohla sehr\u00e1t roli p\u0159i dod\u00e1v\u00e1n\u00ed t\u011bchto \u017eivotn\u011b d\u016fle\u017eit\u00fdch slou\u010denin na na\u0161i planetu.<\/p>\n\n
V\u011bdci p\u016fvodn\u011b doufali, \u017ee odeberou vzorky z atmosf\u00e9ry i zeminy komety, ne\u017e se baterie sondy Philae vybij\u00ed. Vrt\u00e1k sondy Philae v\u0161ak narazil na neobvykle tvrd\u00fd povrch, co\u017e nazna\u010duje, \u017ee povrch komety nen\u00ed pevn\u00e1 hornina, ale je pouze zmrzl\u00fd.<\/p>\n\n
