Objev vz\u00e1cn\u00e9ho achondritu<\/h2>\n\n
    \n
  1. ledna 2024 vstoupil t\u0159\u00edmetrov\u00fd asteroid s n\u00e1zvem 2024 BX1 do zemsk\u00e9 atmosf\u00e9ry a vytvo\u0159il tak jasn\u011b z\u00e1\u0159\u00edc\u00ed ohnivou kouli, kter\u00e1 byla viditeln\u00e1 ve velk\u00e9 \u010d\u00e1sti Evropy. Asteroid se z\u0159\u00edtil pobl\u00ed\u017e n\u011bmeck\u00e9ho Berl\u00edna a v\u011bdci rychle dorazili na m\u00edsto, aby \u00falomky vyzvedli a klasifikovali.<\/li>\n<\/ol>\n\n

    K jejich p\u0159ekvapen\u00ed byly \u00falomky identifikov\u00e1ny jako achondrit<\/strong>, vz\u00e1cn\u00fd typ meteoritu, do jeho\u017e kategorie bylo dosud za\u0159azeno jen 80 ze 70 000 nalezen\u00fdch \u00falomk\u016f meteorit\u016f. Achondrity jsou pojmenov\u00e1ny podle prvn\u00edho zn\u00e1m\u00e9ho meteoritu tohoto typu, kter\u00fd dopadl v roce 1836 pobl\u00ed\u017e francouzsk\u00e9 vesnice Aubres.<\/p>\n\n

    Na rozd\u00edl od v\u011bt\u0161iny meteorit\u016f, kter\u00e9 maj\u00ed tenkou krustu z \u010dern\u00e9ho skla, achondrity<\/strong> nejsou leskl\u00e9 nebo tmav\u00e9. M\u00edsto toho p\u0159ipom\u00ednaj\u00ed \u0161edou \u017eulu, co\u017e zt\u011b\u017euje jejich nalezen\u00ed v ter\u00e9nu. Lovci meteorit\u016f proto museli oblast pobl\u00ed\u017e Berl\u00edna prohled\u00e1vat po \u00falomc\u00edch asteroidu, co\u017e se uk\u00e1zalo jako n\u00e1ro\u010dn\u00fd \u00fakol.<\/p>\n\n

    V\u00fdznam objevu<\/h2>\n\n

    Objev meteoritu achondritu<\/strong> v N\u011bmecku je v\u00fdznamn\u00fd z n\u011bkolika d\u016fvod\u016f. Zaprv\u00e9 v\u011bdc\u016fm poskytuje nov\u00fd materi\u00e1l ke studiu, kter\u00fd jim m\u016f\u017ee pomoci l\u00e9pe pochopit p\u016fvod achondrit\u016f. Zadruh\u00e9 p\u0159esn\u00e1 dr\u00e1ha asteroidu 2024 BX1 m\u016f\u017ee v\u011bdc\u016fm pomoci ur\u010dit, odkud poch\u00e1z\u00ed.<\/p>\n\n

    Mo\u017en\u00e9 p\u016fvody achondrit\u016f<\/h2>\n\n

    P\u016fvod achondrit\u016f<\/strong> je st\u00e1le tajemstv\u00edm, ale v\u011bdci navrhli n\u011bkolik teori\u00ed. Jednou z mo\u017enost\u00ed je planetka Nysa, skupina planetek, kter\u00e9 ob\u00edhaj\u00ed kolem Slunce mezi Marsem a Jupiterem. Dal\u0161\u00edm kandid\u00e1tem je planetka 3103 Eger, kter\u00e1 se nach\u00e1z\u00ed v p\u00e1su planetek. T\u0159et\u00ed mo\u017enost\u00ed je planeta Merkur.<\/p>\n\n

    Merkur jako potenci\u00e1ln\u00ed zdroj<\/h2>\n\n

    P\u0159esto\u017ee je Merkur potenci\u00e1ln\u00edm zdrojem achondrit\u016f<\/strong>, n\u011bkte\u0159\u00ed astronomov\u00e9 to v tomto p\u0159\u00edpad\u011b pova\u017euj\u00ed za nepravd\u011bpodobn\u00e9. Vypo\u010dten\u00e1 dr\u00e1ha asteroidu 2024 BX1 nazna\u010duje, \u017ee poch\u00e1z\u00ed z oblasti mimo ob\u011b\u017enou dr\u00e1hu Zem\u011b, co\u017e by zt\u011b\u017eovalo jeho p\u0159\u00edm\u00fd p\u016fvod na Merkuru. Je v\u0161ak mo\u017en\u00e9, \u017ee Merkur mohl v minulosti vymr\u0161tit achondrity<\/strong> do p\u00e1su planetek a jeden z nich se mohl dostat a\u017e na Zemi.<\/p>\n\n

    V\u011bdeck\u00e1 hodnota objevu<\/h2>\n\n

    \u00dalomky meteoritu achondritu<\/strong> 2024 BX1 budou m\u00edt nevy\u010d\u00edslitelnou hodnotu pro v\u011bdeck\u00fd v\u00fdzkum.

Objev tohoto vz\u00e1cn\u00e9ho meteoritu je d\u016fkazem d\u016fle\u017eitosti v\u00fdzkumu meteorit\u016f a potenci\u00e1lu nov\u00fdch objev\u016f pro objasn\u011bn\u00ed z\u00e1had na\u0161eho vesm\u00edru.<\/p>","protected":false},"excerpt":{"rendered":"
