    J\u00e1dro bez planety<\/h2>\n

    V ran\u00e9 slune\u010dn\u00ed soustav\u011b se mal\u00e1 planet\u00e1rn\u00ed t\u011blesa roztavila a rozvrstvila stejn\u011b jako Zem\u011b: \u017eelezo kleslo do st\u0159edu. Kdy\u017e jedno z nich zni\u010dila sr\u00e1\u017eka, \u00falomky jeho j\u00e1dra ze \u017eeleza a niklu se rozlet\u011bly do vesm\u00edru a putovaly j\u00edm miliardy let. Jeden z nich m\u011bl p\u0159ed sebou dlouhou cestu na sever \u0160v\u00e9dska.<\/p>\n <\/div>\n

    Dopad u \u0159eky Muonio<\/h2>\n

    Zhruba p\u0159ed milionem let \u00falomek dopadl do dne\u0161n\u00edho \u0161v\u00e9dsk\u00e9ho Laponska pobl\u00ed\u017e \u0159eky Muonio. Doby ledov\u00e9 jeho kusy zasypaly a roznesly, prvn\u00ed z nich na\u0161li roku 1906. Meteorit dostal jm\u00e9no Muonionalusta a za\u0159adili ho mezi jemn\u00e9 oktaedrity (typ IVA). Cen\u00ed se pro kr\u00e1su sv\u00e9 vnit\u0159n\u00ed struktury.<\/p>\n <\/div>\n

    Uvnit\u0159 \u017eeleza krystalizovaly dv\u011b slitiny niklu a \u017eeleza, kamacit a taenit, do propl\u00e9taj\u00edc\u00edch se p\u00e1s\u016f, zat\u00edmco j\u00e1dro chladlo zhruba o stupe\u0148 za tis\u00edc let. Tak vznikly Widmanst\u00e4ttenovy obrazce, geometrick\u00e1 m\u0159\u00ed\u017eka, kter\u00e1 se tvo\u0159\u00ed jen miliony let ve vesm\u00edru. Vyrobit ani napodobit ji nelze. Kdy\u017e se vyle\u0161t\u011bn\u00fd pl\u00e1tek nalept\u00e1 kyselinou, obrazec se objev\u00ed, v ka\u017ed\u00e9m \u0159ezu jin\u00fd. Z takov\u00e9ho pl\u00e1tku je cifern\u00edk.<\/p>\n
