Ukuwa kwama-meteorite kanye nokuvela kwezingcezu zesikhala eMhlabeni kuyaqhubeka nokumangaza. kokubili umphakathi wesayensi kanye nomphakathi jikelele. Ezinsukwini ezimbalwa nje, izenzakalo ezimbili ziye zabeka ukukhanya kulezi zindikimba zasezulwini: ngakolunye uhlangothi, umthelela omangalisayo we-meteorite eningizimu-mpumalanga ye-United States, kanti ngakolunye, indali eseduze eNew York I-Martian meteorite enkulu kunazo zonke ezake zatholakala emhlabeni wethuZombili izehlakalo, nakuba zihlukile, zabelana ngokumangala nokuhambisana kwesayensi okuvuswe ama-meteorite, aziwa ngekhono lawo lokuhlinzeka ngolwazi mayelana nomsuka nokubunjwa kwezinye izindikimba kusistimu sonozungezilanga.
Lezi ziqephu zakamuva zibonisa izici ezimbili ze-meteoric phenomenon.: umthelela oqondile nobonakalayo empilweni yansuku zonke kanye nocwaningo nokuqoqwa kwezingcezu zesikhala eziyingqayizivele. Kusukela ekudidekeni okudalwe ukuqhuma kwetshe le-cosmic emini bebade e-United States kuya ekubeni nesithakazelo samazwe ngamazwe sokuba nensalela evela kwenye iplanethi, ama-meteorite ayaqhubeka nokuxhuma uMhlaba nezimfihlakalo zendawo yonke, futhi asikhumbuza isidingo sokuqhubeka nokucwaninga nokulondoloza ulwazi oluphethe.
I-Meteorite iwela eningizimu-mpumalanga ye-United States bese ishaya i-Georgia
Ntambama ngoLwesine, Juni 26, I- meteorite yakhanyisa esibhakabhakeni saseGeorgia futhi yabangela isiyaluyalu esiphawulekayo ezindaweni ezihlukahlukene zase-United States.Izakhamizi zaseGeorgia, eSouth Carolina, eNorth Carolina naseTennessee zibone umlilo ovuthayo uzulazula esibhakabhakeni, ngokusho kwemibiko evela kuzo zombili izifunda. I-American Meteor Society njenge Isevisi Yesimo Sezulu Kazwelonke (NWS)Ngezikhathi zasemini, inqwaba yabantu yathwebula into ehamba ngayo ngevidiyo, kwezinye izikhathi ihambisana nomsindo omkhulu owengeza idrama endaweni yesigameko.
Lo mkhuba wawubonakala nakakhulu lapho Ucezu lwashayisa ikhaya eHenry County, eGeorgiaUmphumela waba imbobo ophahleni kanye nokulimala phansi, nakuba ngenhlanhla, akukho kulimala okubikiweIzakhamuzi ngokwazo zibike ukuthi ziqale zizwa ukuqhuma okukhulu futhi, lapho zihlola indlu, zathola idwala eligxilile ngemuva kokugqekeza izingqimba eziningana zophahla nephansi. Iziphathimandla zendawo ziwuqinisekisile lo monakalo futhi ziyaqhubeka nokuphenya umthombo wangempela wento.
I-NWS e-Atlanta yaqoqa imibiko eminingi futhi yaqala ukuhlaziya isimo, nakuba i I-U.S. Geological Survey ikhiphe umnyakazo wokuzamazama komhlaba ohambisana nomthelela. Ngokwengxenye yayo, i Uhlelo lweNational Weather Service ukuthola umbani yaqopha umzila okhanyayo ezindaweni ezisemngceleni phakathi kweNorth Carolina neVirginia, okuhambisana nesikhathi nemibiko yezakhamizi.
Ngokusho kochwepheshe, Into cishe kwakuyi-meteorite, nakuba amathuba okuba khona kwemfucumfucu yasemkhathini azange akhishwe ekuqaleni.I-American Meteor Society ithole cishe imibiko engu-150 yebhola lomlilo, eliphinde labonwa ezindaweni eziseFlorida. Abasebenzi bezimo eziphuthumayo kanye nabezesimo sezulu abasemthethweni bayaqhubeka nokuqapha indawo, bexwayisa umphakathi ukuthi ugweme ukuphatha noma yiziphi izingcezu ezisolisayo futhi uzibikele iziphathimandla ezifanele.
I-Martian meteorite NWA 16788: ucezu oluyingqayizivele oluzothengiswa endalini
Ngenkathi izindaba zisagxile emiphumeleni ye-Georgia meteorite, indlu yendali yoSuthu eNew York imemezele ukuthengiswa okuzayo kwe-meteorite yaseGeorgia. I-meteorite yemvelaphi ye-Martian ibhekwa njengenkulu kunazo zonke futhi eyigugu kakhulu etholwe kuze kube manje eMhlabeniOkubizwa nge-“NWA 16788” kugqama ngosayizi wayo ohlaba umxhwele, nge Ama-24,67 kilos wesisindo, kanye nombala wayo obomvu oyingqayizivele, ohlobene nomsuka wayo waseMartian. Lesi siqeshana, esizokhonjiswa oSuthwini kusukela ngoJulayi 8 kuya ku-15 ngaphambi kokuba idayiswe ngomhlaka-16, kulindeleke ukuthi silande inani lentengo ephakathi kuka-$2 no-$4 million, okungenza kube yisibonelo esibiza kakhulu sikaMartian esake sathengiswa endalini.
I-meteorite yatholakala ku Novemba 2023 ngumzingeli ongaziwa esifundeni sase-Agadez, eNiger, futhi ukuhlobana kwayo kwesayensi akunakuphikwa: imelela ubuningi obungama-70% ngaphezu kwanoma iyiphi enye ingxenye eyaziwayo ye-Martian futhi kulinganiselwa ukuthi Yakha cishe u-6,6% wayo yonke impahla ye-Martian etholakala emhlabeni wethu.Ngokokuhlaziya, ukukhishwa kwayo ebusweni be-Mars kwakubangelwa umthelela we-asteroid enamandla, eyaguqula ingxenye yokwakheka kwayo kwangaphakathi ibe yingilazi futhi yadala izindawo zoqweqwe lwe-vitreous ezibonakala ngemva kokudlula kwayo emkhathini woMhlaba.
USuthu nososayensi bagcizelela ukubaluleka kwe-NWA 16788 njenge ubufakazi obuphathekayo be-geology ye-MarsLezi zingcezu eziyivelakancane zinikeza ulwazi olubalulekile lokuqonda ukwakheka nokuvela kwe-Red Planet, ngokunikeza ukufinyelela ezintweni ezazingafinyeleleki ngaphambilini. Kuma-meteorite angaphezu kuka-77.000 400 abhaliswe ngokusemthethweni emhlabeni wonke, angaba ngu-374 kuphela avela kuMartian, futhi amaningi awo awekho makhulu kunezingcezu ezimbalwa. Isamba senani lama-Martian meteorite ahlonziwe linesisindo esingamakhilogremu angu-XNUMX, futhi ucezu oluzothengiswa endalini lumelela ingxenye enkulu yaleli nani.
Ukudayiswa kwendali kwe-meteorite yalolu hlobo kuphinde kwavula inkulumo-mpikiswano nge ukuthengiswa kwezingcezwana zangaphandle komhlaba ngenani lomlando nesayensiAbanye ochwepheshe baxwayisa ngengozi yezingcezu eziyingqayizivele ezigcina ezandleni zangasese, ezithikameza ukufinyelela ocwaningweni. Noma kunjalo, okulindelwe kuphezulu, futhi ukubhida kwamazwe ngamazwe kulindeleke ngenxa yokuhluka kokutholiwe.
Ukubaluleka kwama-meteorite kwesayensi nomphakathi
Zombili izehlakalo, nakuba zihlukile ngemvelo nangesilinganiso, ziyagqama ukubaluleka kwama-meteorite njengabathwali bolwazi oluyiguguUmthelela ofana nowaseGeorgia uyisikhumbuzo sokuthi uMhlaba uhlala usengozini yokufika kwezinto zasemkhathini. Ngaphezu kwalokho, ukucwaninga nokulondolozwa kwama-meteorite njenge-NWA 16788 Bavumela umphakathi wesayensi ukuba ujulise ulwazi lwawo kokubili isimiso sonozungezilanga nezinqubo ezakha amaplanethi.
Ubunzima bokuthola nokuthola izingcezu zangempela kukhulisa inani lazo. Ngokwesibonelo, eNyakatho Melika, kubhalwe izingcezu ezimbalwa kuphela. Ama-meteorite amasha ayi-15 ngonyaka Futhi endabeni yalabo abasuka kumaplanethi, inani cishe lincane. Ukuze ujulise ulwazi lwakho ngalezi zindikimba zasemkhathini, ungase ube nesithakazelo sokufunda ngazo izinyanga zaseMars.
Intshisekelo yomhlaba wonke eyenziwa yilezi zenzakalo ibonisa ukuthi ama-meteorite ahlala kanjani eyizici ezibalulekile, hhayi nje kusayensi yasemkhathini, kodwa nasemikhubeni ethandwayo nenkumbulo ehlangene. Lokhu kuthakazelisa nokucwaninga kuyaqhubeka nokugqugquzela ilukuluku kanye nokufuna izimpendulo ngendawo yethu endaweni yonke.
