Ukuwa kweemeteorites kunye nokubonakala kwamaqhekeza asesibhakabhakeni eMhlabeni kuyaqhubeka ukumangala. zombini uluntu lwenzululwazi kunye noluntu ngokubanzi. Kwiintsuku nje ezimbalwa, iminyhadala emibini iye yabeka ukukhanya kwezi zidalwa zasezulwini: kwelinye icala, ifuthe elimangalisayo lemeteorite kumazantsi mpuma eUnited States, kwelinye, ifandesi ekufuphi eNew York. I-Martian meteorite enkulu eyakha yafunyanwa kwiplanethi yethuZombini ezi ziganeko, nangona zahlukile, zabelana ngoloyiko kunye nokufaneleka kwezesayensi okuvuswe ziimeteorites, ezaziwa ngokukwazi kwazo ukunika ulwazi malunga nemvelaphi kunye nokubunjwa kweminye imizimba kwisixokelelwano selanga.
Ezi ziqendu zamva nje zibonisa imiba emibini yesiganeko semeteoric.: impembelelo ethe ngqo kunye nebonakalayo kubomi bemihla ngemihla kunye nokufunda kunye nokuqokelela amaqhekeza ahlukeneyo wendawo. Ukususela kwisiphithiphithi esiveliswe kugqabhuko-dubulo lwelitye le-cosmic emini emaqanda e-United States ukuya kumdla wamazwe ngamazwe wokuba ne-relic evela kwenye iplanethi, iimeteorite ziyaqhubeka nokudibanisa uMhlaba kwiimfihlelo ze-cosmos, kwaye zisikhumbuza ngemfuneko yokuqhubeka nophando kunye nokugcina ulwazi oluluphetheyo.
I-Meteorite iwela umzantsi-mpuma we-United States kwaye ibethe iGeorgia
Emva kwemini ngoLwesine, nge-26 kaJuni, I<em>meteorite yakhanyisa isibhakabhaka saseGeorgia yaza yabangela isiphithiphithi kwiindawo ezahlukeneyo zaseUnited States.Abahlali baseGeorgia, eMzantsi Carolina, eNorth Carolina naseTennessee babone ibhola yomlilo eqaqambileyo ijikeleza esibhakabhakeni, ngokweengxelo ezivela kuzo zombini. Umbutho weMeteor waseMelika njenge Inkonzo yeMozulu yeSizwe (NWS)Ngentsimbi yeshumi elinambini emini, abantu abaninzi bathatha indawo yento kwividiyo, bekhatshwa kwezinye iimeko ngesithonga esikhulu esongeza idrama kwindawo leyo.
Lo mcimbi wawuphawuleka ngakumbi xa Isiqwenga sabetha ikhaya eHenry County, eGeorgiaIsiphumo saba ngumngxuma eluphahleni kunye nomonakalo emgangathweni, nangona ngethamsanqa, akukho nzakala baxeliweyoAbahlali ngokwabo baxela ukuba baqale beva isithonga esikhulu kwaye, emva kokuphonononga indlu, bafumanisa ilitye elizinzisiweyo emva kokugqobhoza iileya ezininzi zophahla kunye nomgangatho. Abasemagunyeni basekuhlaleni bawuqinisekisile lo monakalo kwaye bayaqhubeka nokuphanda owona mthombo wezinto eziphathekayo.
I-NWS e-Atlanta iqokelele iingxelo ezininzi kwaye yaqala ukuhlalutya imeko, nangona i U.S. Geological Survey ikhuphe iintshukumo zenyikima ezayanyaniswa nefuthe. Ngokwenxalenye yayo, i Inkqubo yokubona umbane yeNkonzo yeMozulu yeSizwe urekhode umzila oqaqambileyo kwimimandla yemida phakathi kweNorth Carolina neVirginia, ehambelana nexesha kunye neengxelo zabemi.
Ngokweengcali, Le nto mhlawumbi yayiyimeteorite, nangona ukuba nokwenzeka kobutyobo bendawo akuzange kuthintelwe ekuqaleni.I-American Meteor Society ifumene iingxelo ezimalunga ne-150 zebhola yomlilo, ekwabonwa kwiindawo zaseFlorida. Abasebenzi bemeko yonxunguphalo kunye neenkonzo zemozulu ezisemthethweni ziyaqhubeka nokubeka esweni lo mmandla, belumkisa uluntu ukuba luphephe ukuphatha naziphi na iziqwenga ezirhanelekayo kwaye bazixele kwabasemagunyeni abafanelekileyo.
I-Martian meteorite NWA 16788: iqhekeza elikhethekileyo eliza kuthengiswa
Ngelixa iindaba zisagxile kwiziphumo zeMeteorite yaseGeorgia, indlu yefandesi yeSotheby eNew York yabhengeza ukuthengiswa okuzayo kwe-meteorite yaseGeorgia. I-meteorite yemvelaphi yaseMartian ithathwa njengeyona inkulu kwaye ixabiseke kakhulu efunyenweyo ukuza kuthi ga ngoku eMhlabeniInto ebizwa ngokuba yi "NWA 16788" ivelele zombini ngobukhulu bayo obumangalisayo, kunye Ubunzima be-24,67 kilos, kunye nombala wayo obomvu oyingqayizivele, onxulumene nemvelaphi yayo yaseMartian. Eli cwecwe, eliza kuboniswa eSotheby ukusuka ngomhla we-8 ukuya kwi-15 kaJulayi ngaphambi kokuba lithengiswe ngomhla we-16, kulindeleke ukuba lilande ixabiso eliqikelelwa phakathi kwe-2 kunye ne-4 yezigidi zeedola, nto leyo eya kuyenza ibe ngowona mzekelo we-Martian obiza kakhulu owakhe wathengiswa kwifandesi.
Imeteorite yafunyanwa kwi NgoNovemba 2023 ngumzingeli ongaziwa kummandla we-Agadez, eNiger, kwaye ukufaneleka kwayo kwezenzululwazi akunakuphikiswa: imele i-70% yobunzima ngaphezu kwayo nayiphi na enye iqhekeza leMartian eyaziwayo kwaye kuqikelelwa ukuba Ibandakanya malunga ne-6,6% yazo zonke izinto zeMartian ezifumaneka kwiplanethi yethu.Ngokohlalutyo, ukukhutshwa kwayo kumphezulu we-Mars kwakubangelwa yimpembelelo ye-asteroid enamandla, eyaguqula inxalenye yokwakheka kwayo kwangaphakathi kwiglasi kwaye yenza iindawo ze-vitreous crust ebonakalayo emva kokudlula kwi-atmosphere yoMhlaba.
ISotheby kunye nezazinzulu zikrwelela ixabiso le-NWA 16788 njenge ubungqina obubambekayo bejoloji yeMarsEzi ziqwenga ezinqabileyo zibonelela ngolwazi olubalulekileyo lokuqonda ukubunjwa kunye nokuvela kwePlanethi eBomvu, ngokubonelela ngokufikelela kwizinto ezazingafikeleleki ngaphambili. Kwiimeteorites ezingaphezu kwama-77.000 400 ezibhaliswe ngokusemthethweni ehlabathini lonke, zingama-374 kuphela ezinemvelaphi kaMartian, yaye uninzi alukho bukhulu kuneziqhekeza ezimbalwa. Itotali yenani leMartian meteorites ezichongiweyo zinobunzima obumalunga neekhilogram ezingama-XNUMX, kwaye iqhekeza eliza kuthengiswa limele inxalenye ebalulekileyo yale totali.
Ifandesi yemeteorite yolu hlobo iphinde yavula ingxoxo malunga ne ukuthengiswa kwamaqhekeza angaphandle komhlaba anexabiso lembali nenzululwaziEzinye iingcali zilumkisa ngomngcipheko weziqwenga ezizodwa eziphela ezandleni zangasese, zithintela ukufikelela kuphando. Nangona kunjalo, okulindelekileyo kuphezulu, kwaye ibhidi yamazwe ngamazwe ilindeleke ngenxa yokungaqhelekanga kokufunyanwa.
Ukubaluleka kweemeteorites kwinzululwazi kunye noluntu
Zombini iziganeko, nangona zahlukile kwindalo kunye nesikali, zigqamile ukubaluleka kweemeteorites njengabathwali bolwazi oluxabisekileyoImpembelelo efana neGeorgia sisikhumbuzo sokuba uMhlaba uhlala usengozini ekufikeni kwezinto zendawo. Ngaphezu koko, uphononongo kunye nokugcinwa kweemeteorites ezifana ne-NWA 16788 Bavumela uluntu lwenzululwazi ukuba lwenze nzulu ulwazi lwayo zombini isixokelelwano sezijikelezi-langa kunye neenkqubo ezibumba iiplanethi.
Ubunzima bokufumana kunye nokubuyisela amaqhekeza ayinyani kwandisa ixabiso labo. Ngokomzekelo, kuMntla Merika, ziingceba ezimbalwa kuphela ezibhaliweyo. Iimeteorite ezintsha ezili-15 ngonyaka Kwaye kwimeko yemvelaphi yeplanethi, inani liphantse lingabalulekanga. Ukwenza nzulu ulwazi lwakho ngezi zidalwa zisezulwini, unokuba nomdla wokufunda ngazo iinyanga zikaMars.
Umdla wehlabathi jikelele oveliswa zezi ziganeko ubonisa indlela iimeteorite ezihlala ngayo zizinto eziphambili, hayi kwisayensi yendawo kuphela, kodwa nakwinkcubeko edumileyo kunye nenkumbulo edibeneyo. Lo mtsalane kunye nophando luqhubela phambili ukuqhubela umdla kunye nokukhangela iimpendulo ngendawo yethu kwindalo iphela.
