Goba eziwa (Hoba) - ehlabathini inkulu

"Space ziyiphendula" ziwe emhlabeni kaninzi. Baya kuza zobungakanani ezahlukeneyo, kodwa uninzi ngamaqhekeza amancinci, leyo sazi imvelaphi ekuseni akukho lula. Izazi baye bakwazi ukubala ukuba phantse 100 kweetoni eziliwaka izinto eziwe liwela ngonyaka Earth. Noko ke, phakathi kwabo, zifumaneka ngamaxesha athile kunye aerospace omkhulu. Enye yezi imizimba yesiqalo yi Goba - lizwe likhulu awe Ayifumaneki.

Kutheni ayevela zinqabile

Abantu abaninzi umbuzo: "awe kufika Kutheni na ngaphesheya njalo ngamaxesha?" Eneneni, 100 amawaka iitoni ngonyaka ngamnye - umzobo kunokuba elikhulu, kodwa amaqhekeza ngokuqhelekileyo esibhakabhakeni zalishumi eekhilogram eziliqela, kwaye maxa wambi nkqu gram. ukuqonda Asinguye wonke umntu ukuba phantsi kweenyawo zakhe ayikho nje ingqalutye, a space. Ubukhulu ezincinane awe ngenxa yokuba umzimba engaphandle itshiswa kwaye izibane xa efika kulo moya ujikeleze umhlaba. Inkqubo ablation, kwaphumela ekuncipheni kakhulu ubunzima le into. Uninzi kweqokobhe ukuya kumphezulu womhlaba yasezulwini akuthethi ukufikelela konke konke. Hi ndlela leyi, ablation - oko xa kukho phezu a amasuntswana into eqinileyo entrained kumsinga egesi eshushu okanye ngendlela radiation.

Njengoko kwafunyaniswa emkhathini ngobukhulu planethi?

Ubungqina njengoko zimpahla inkulu Goba wawa emhlabeni, akusekho ukufumana. Isibakala sokuba oku kwenzeka ngamaxesha ababephila phambi kokubhalwa kwembali, xa umntu ibizezamandulo babengazi umbhalo. Kodwa Wafumana kwakukho "ilitye wamazulu 'esikhulu eyona ndlela banal. Ngexesha lokulima umhlaba ngumfama wayo savanna Afrika eNamibia ukohlukana into ikhuba enkulu kakhulu. Zisusa ilizwe, umlimi waqonda ukuba shift ukusuka kwindawo yalo rhamncwa nje akunakwenzeka. umzimba Strange watsala ingqalelo izazinzulu abaye baqinisekisa imvelaphi yayo komhlaba. Baye ezabiwe kokufunyanwa enegama elifanayo naleyo ifama apho kwafunyanwa - Hoba West Farm. Esi siganeko senzeke ngo-1920.

Umfama uye wenza ukufunyanwa ekhethekileyo, ekuthiwa Jacobs Brits. Wafika Namibia evela UK. A buza unique wamnika ithuba lokuba uyatyetyiswa ngokuthengisa emkhathini kwimimandla njengezikhumbuzo okanye ezinye iinjongo. Kodwa ingqalelo amanyathelo ayilunganga yaye akazange sokuceba. Umfama wanika nifumana wakhe Government of Namibia, hayi ngoko nangoko, Kakade ke, kodwa wasondeza.

Ubunzima kunye nemilinganiselo emkhathini inkulu

Balinganise eziwa oosonzululwazi baye baphumelela. Baye kwenziwe izibalo kwaye bafumanisa ukuba xa sibona i zimpahla bumalunga 66 neetoni. Ukongeza, i-lethiyori ubeke phambili ukuba ngexesha ukuwa Umhlaba, malunga nama-80 amawaka. Kwiminyaka eyadlulayo, le ubunzima bomzimba ngaphakathi iitoni ezingama-90. Kodwa namhlanje singakwazi ukubona ton-60 zimpahla Goba njengoko ukhukhuliseko, wabona kude iziqwenga zophando kunye nokonakaliswa kwabatyeleli kakhulu ukwehlisa ubunzima bayo.

Imilinganiselo ekuneni Goba namhlanje zenza 2,7h2,7h0,9 m umthamo wayo -. M³ 9.

Ukubunjwa zimpahla

Ukususela izifundo ezininzi, oosonzululwazi baye bakwazi ukufumana ulwazi nokwakhiwa "uhlanga". Ngokusemthethweni isaziso ukuba zimpahla Goba (Namibia, 1920 yg) iqulethe 84% yentsimbi, 15% nickel kunye ukungcola ayibe. Malunga ne-1% kukho ubumdaka nezinye izinto. Umaleko ongaphezulu ibandakanya hayidroksayidi yentsimbi. isakhiwo crystalline sichazwa nickel Ataxia.

Ngenxa yoko, Meteor Goba ibangelwa yentsimbi. Ukuze ukwazi ukufaka ukuba awe ngezigaba zohlulwa ngokwendidi 3, ngokusekelwe ukwakhiwa kwawo:

1. Ayevela ngezinto okuthiwa ngamatye.
2. ayevela metal ebizwa siderites okanye intsimbi.
3. "Aliens" zemathiriyeli mixed kuthiwa intsimbi-ilitye.

Classification kunceda ukuba iqela zesampulu imvelaphi efanayo. izinto eziwe abe yinxalenye umhlaba, litye okanye satellite, nayiphi na into inkqubo solar ukuba ngoku ikhona okanye eyayikho ngaphambili. Kodwa oluhlobo ayikho kodwa yokugqibela, oko kwaye iza kwandiswa.

Goba puzzles apho umngxuma?

A eziwa Isazinzulu enkulu yaphosa uthotho puzzle. Omnye wabo - kukunqongophala wentaba. Ngesizathu esithile, undwendwe isithuba mihlaba ukuze unkabi ukuba akwazi ukugcina ukumila kwaye musa ndibachithachithe yimfumba kobutyobo. intlekele Ukuwa lwenzeke, kwaye Umgodi ekhohlo. Nangona wentaba obuncinane abonakale uze baphele kunye sicatshulwa kwexesha. Kusenokwenzeka ukuba ukuwa yenzekile ngexesha engile encinane kakhulu.

Enye imfihlelo - ifomu eyahlukileyo

Meteorite Goba ngokumila engaqhelekanga kakhulu. kwamakhulu Huge Kubonakala ngathi parallelepiped phantse ogqibeleleyo. Yohambo yezinto nkqubo solar fom wawa emhlabeni kunqabile kakhulu, yaye ezincinane kakhulu giant Goba.

Izazinzulu ayimangalisi kuphela imilo kodwa ubunjani kumphezulu olungaphandle zimpahla. Osanda kuba mpuluswa, kwaye umphezulu wayo phantse tyaba. Ekuqaleni, umbala umzimba cosmic kwaba blue-black, kodwa koMhlaba iqulethe carbon dioxide, nesinyithi lweenkobe, apho zimpahla waba ebomvu.

Ukuhlaselwa abakhenkethi

Kamsinya nje Kwazeka oko apho zimpahla Goba e Jacobs Field Brits yaqalisa lundwendwe labakhenkethi. Banyathelane izilimo chipped izijungqe kwinkumbulo. Ukuze baphile kunye nomsebenzi efama iye nzima, kunye namafama saqala ukucela urhulumente ukuba ukhuselo. Kwakunjalo kwiminyaka emininzi phambi kokuba urhulumente lwaseNamibia wagqiba ukuthobela isicelo zomlimi. Meteorite Goba yaba yamagugu esizwe ngo-1955 kuphela. Noko ke, abakhenkethi abayinanzanga ban karhulumente kwaye waqhubeka NOKUCUKUCEZA zezikhumbozo.

Ukufika kweziko kubakhenkethi

ukudluliselwa lokugqibela umhlaba wefama "Goba-West" kunye zimpahla ngokwayo kwenzeka ngo-1988. iminyaka emi-3 phambi kwesi siganeko, inkampani Rossing Uranium Ltd. I undimisele umlindo ngeenxa zimpahla ngemali ephuma kwiingxowa zaso. Nokutshatyalaliswa nomphambukeli ayiphumelelanga ukuba ayeke. iziko kubakhenkethi lasekwa emva ukutshintshwa komhlaba macala. indawo yayo enqatyisiweyo, kunye nentlawulo emnyangweni kuthathwe. Le mali iya muhle ziko. Ngoko ke hamba uye zimpahla futhi izithombe kwi nemvelaphi yakhe ngoku ibiza imali entle.

Eli ziko ngokwayo ifana igadi yezityalo. Kukho ndatyala kuyo imithi ezahlukeneyo, iibhodi ulwazi ibekwe. Macala onke idibane ngasembindini kwingoma ecocekileyo, ibekwe phakathi enkulu yemidlalo emithathu tiered yaphandle kwaye amanyathelo ekhokelela "ligorha sihlandlo." Ekuxhobiseni iziko kubakhenkethi, abasemagunyeni baqonde ukuba abantu apho nje ngenxa yokuba i zimpahla Goba, ngoko ke akukho anenzondelelo kakhulu, nokutyetyiswa panorama ezingqongileyo. Ezinye iibhodi Ulwazi musa siqulathe iinkcukacha ezininzi ezibalulekileyo ezihlekisayo. Omnye wabo kwathiwa ngeelwimi ezininzi: "Kulumkele awe esibhakabhakeni eziwayo."

Enyanisweni, iziko kubakhenkethi emhlabeni zimpahla usenokuba iphetshwe. Inyaniso yokuba ngo-1954 kweli litye imvelaphi yokuba wayefuna ukuthenga Natural History Museum eNew York. Kuye labelwe isixa esikhulu semali, kodwa kwakufuneka enze umsebenzi engenakwenzeka phambi kwabasebenzi lwembali le: ukuba iphakamise kwaye ukususa umgama omde into eyahlukileyo. Fumana isisombululo sale ngxaki yaye, ke ngoko, ingcamango kokuthenga lwembali wala.

iqhawe double

Meteorite Goba uyakwazi zizakujongwa njengo uyintshatsheli kabini. Okokuqala, njengokuba kuchaziwe ngaphambili, oku yeyona nto inkulu zesibhakabhaka ezifumaneka eMhlabeni. Enyanisweni, lo into yokuba - iqhekeza inkulu lomthonyama yentsimbi emhlabeni. Okwesibini - zange kuva. Malunga 80 amawaka. Iminyaka umthunywa lamazulu kanye wawa apho.
