Emva kwemini yomhla wesi-8 kweyoKwindla, umlilo omangalisayo wadlula esibhakabhakeni phezu kwentshona yeYurophu.ishiya amawaka abantu bengathethi kwaye iifowuni zabo zikhala. Kwimizuzwana embalwa nje, into abaninzi abayibiza ngokuba yibhola yomlilo enkulu yakhanyisa isibhakabhaka yaza yavelisa isandi esasivakala kwiindawo ezahlukeneyo zaseJamani nakwamanye amazwe angabamelwane. Oko kwakubonakala ngathi yinto elula nemangalisayo yeenkwenkwezi kwaphela kusenza iindaba eziphambili xa kwaqinisekiswa ukuba inxalenye yale nto yayiwele eluphahleni lwendlu eJamani.
Impembelelo engaqhelekanga yemeteorite encinci kwindlu eKoblenzIsiganeko kwilizwe lombuso laseRhineland-Palatinate ngequbuliso sazisa ingqalelo ebukhali ekuboneni izinto ezikufutshane noMhlaba kunye nokuba semngciphekweni kweendawo ezihlala abantu kumatye abonakala ngathi mancinci ngobukhulu. Nangona bekungekho zingozi, esi siganeko sabangela umonakalo wezinto ezibonakalayo kwaye saphakamisa uluhlu olude lwemibuzo: yintoni kanye kanye ewileyo, ivela phi, kwenzeka kangaphi into efana nale, kwaye kwenziwa ntoni ukuyifumanisa ngexesha elifanelekileyo.
I-Meteorite eJamani: Le yindlela ebonakala ngayo impembelelo kwindlu eKoblenz
Malunga nentsimbi yesixhenxe ngokuhlwa ngomhla wesi-8 kuMatshi, iqhekeza le-meteorite lawela endlwini ekufutshane neGüls eKoblenz.Le nto yagqobhoza uphahla lwesakhiwo ngokoqobo. Yadala umngxuma omkhulu, olingana nobukhulu bebhola ekhatywayo, yaza yaphelela ngaphakathi kwigumbi lokulala, yonakalisa umgangatho kunye nefenitshala ethile.
Ngexesha lesiganeko bekukho abantu ngaphakathi endlwini, kodwa akukho mntu wayekwigumbi elithe lantlitheka.Ngoko ke, ngokungummangaliso, akukho mntu wenzakeleyo. Abemi beva ingozi kunye nengxolo enkulu enxulumene nayo, kwaye kungekudala emva koko, iinkonzo zongxamiseko zaqaliswa, zavala indawo ukuze zihlole umonakalo kwaye zikhusele indlu.
Amapolisa aseKoblenz achaze le nto “njengomzimba wasezulwini otshisiweyo” owawela eluphahleniBakucacisile kwasekuqaleni ukuba yayingengomathambo enqwelo-moya, idrone, okanye nayiphi na into eyenziwe ngumntu. Abacimi-mlilo, bona, baqinisekisile ukuba iqhekeza lawela uphahla, lagqobhoza isakhiwo, laza laphelela kwigumbi lokulala, apho laqhekeza khona neethayile zomgangatho.
Emva kwengozi, kwaqaliswa umsebenzi wokhuseleko ukuze kulinganiswe izinto ezinokuba yingozi.Abacimi-mlilo benze uvavanyo lwemitha kunye neekhemikhali ukuze bagweme nayiphi na ingozi kubemi. Iziphumo beziqinisekisa: akukho mitha ingaqhelekanga okanye izinto ezinobuthi ezinxulumene ne-meteorite ezifunyenweyo, ngaloo ndlela zisusa naluphi na usongo olungaphaya komonakalo wepropathi.
Amagunya asekuhlaleni nawengingqi aqinisekisile emva koko ukuba imvelaphi yesi siganeko yayiyeyendalo kwaye iyinto yeenkwenkwezi.kwaye yayingenalo naluphi na unxibelelwano nemisebenzi yomkhosi okanye inkunkuma yasesibhakabhakeni evela kwiirokethi okanye iisathelayithi. Ukususela ngelo xesha ukuya phambili, eli tyala laba ngumzekelo wokwenene wendlela ilitye elincinci lasesibhakabhakeni elinokuthi ligqibe ekubeni lingqubane nendlu kwindawo enabantu abaninzi.
Ibhola yomlilo ebonwe kumazwe aliqela aseYurophu
I-meteor eyabangela i-meteorite yaseKoblenz ayizange ibonakale kakuhle esibhakabhakeni saseYurophu.Indlela ekhanyayo yabonakala kangangemizuzwana emithandathu njengoko le nto yayisuka kumzantsi-ntshona isiya kumntla-mpuma, inqumla isibhakabhaka idlula entshona yeJamani kwaye ibhabha phezu kweendawo ezithile zaseFransi, eBelgium, eLuxembourg, eNetherlands, kwaye ngokweengxelo ezithile, kwaneendawo zaseSwitzerland.
AmaNgqina kumazwe amaninzi aseJamani achaza ukukhanya okukhulu, ibhola yomlilo ekhanyayo, kwanombane esibhakabhakeni.Ukusuka eNorth Rhine-Westphalia naseHesse ukuya eRhineland-Palatinate, eSaarland, eBaden-Württemberg naseLower Saxony, iifowuni eziya kumapolisa nakwiinkonzo zongxamiseko ziphindaphindwe ngemizuzu embalwa.
Abemi baxele ukuba babone "into ekhanyayo ebhabhayo enomlilo omfutshane" kunye nesandi esikhulu emva koko.Kwezinye iindawo, kwavakala ingxolo efana nokuqhuma, mhlawumbi eyayinxulunyaniswa ne-shock wave eyavela xa i-meteor yaqhekeka emoyeni. Olu hlobo lwento luqhelekile kwii-bolides, ii-meteors ezikhanyayo kakhulu ezikhupha amandla amaninzi ngexesha elifutshane.
Inethiwekhi ye-fireball ye-AllSky7 kunye ne-International Meteor Organisation zifumene iingxelo ezingaphezu kwama-3.000. malunga nesiganeko, esivumele ukuba indlela yento irekhodwe kwiikona ezahlukeneyo kwaye ngeekhamera ezininzi. Ezi nkqubo, ezisekelwe kwizikhululo ezizenzekelayo ezisasazwa kumazwe aliqela aseYurophu, zenzelwe ngokukodwa ukubona nokubhala iimeteors ezikhanyayo ngokukodwa.
Iividiyo ezininzi ezithathwe ngeefowuni eziphathwayo kunye neekhamera zokhuseleko zabelwana ngazo kwimidiya yoluntu.Oku kube negalelo ekubeni le nto isasazeke kwiiyure ezimbalwa. Kwangaxeshanye, ukwanda kwezithuba kwabangela zonke iintlobo zokucinga, ukusuka kwabo babethetha ngeengceba zeerokethi ukuya kwabo babethetha ngamaqhinga omkhosi anokwenzeka, iingcinga ezathi abasemagunyeni bazilahla ngokukhawuleza.
Ibali lomntu wokuqala: iimpempe, ukukhanya, kunye nokuqhuma
Phakathi kobungqina obuqokelelweyo, obo babantu ababone le meko phantse esitalatweni buyabonakala.eKoblenz ngokwayo nakwiidolophu ezikufutshane. Omnye wabo, uIngo Beller, wayekhwela ibhayisekile yakhe edlula kwindawo yaseGüls xa weva isandi esingaqhelekanga ngaphambi nje kokuba indlu ibethe.
UBeller ubalise ukuba weva ingxolo yomsindo evela phezulu.Oku kwaqala kwamenza wakholelwa ukuba imoto okanye esinye isithuthi esingaqhelekanga sasisondela ngesantya esiphezulu. Ejonga-jonga, wabona kungekho nto ikrokrisayo kwaye wayengazi ukuba oko wayesandula ukukuva kwakunxulumene nento yasesibhakabhakeni eyayiza kuwela eluphahleni lwendlu emva kwemizuzu embalwa.
Kwidolophu yaseKenn, kwisithili saseTrier-Saarburg, omnye umntu obonayo, uGiuliano Krienen, naye wadibana ne-meteor ngamehlo.Ngethuba esebenza kwindawo yakhe yokusebenzela, wabona into ethile idlula esibhakabhakeni “ngesantya esimangalisayo,” nto leyo yena ngokwakhe ayithelekise nendlela ekhawuleza ngokuphindwe kane kuneyenqwelo-moya yejethi.
UKrienen uchaze ukuba kudlule malunga nemizuzu emithathu phakathi kokubonwa kwale nto kunye nokuqhuma awakuvayo emva koko.Eli xesha lihambelana nexesha elinokuthathwa ukuze kuqhekeke kwaye i-shock wave ibonakale phantsi kweemeko ezithile. Kuthathe malunga nemizuzu elishumi ukuqhagamshelana namapolisa, kwimeko apho imigca yayisele igcwele iifowuni ezivela kwabanye abemi abachaphazelekayo.
Amapolisa kwimimandla eyahlukeneyo yaseJamani aqinisekisile ukuba afumene iingxelo ezingenakubalwa. Ngexesha nasemva kokuba i-meteor idlule, abantu abaninzi babezibuza ukuba ingaba kukungqubana kwenqwelo-moya, i-missile, okanye uhlobo oluthile lomsebenzi womkhosi. Impendulo ekhawulezileyo evela kumagunya kunye ne-European Space Agency ngokwayo ivumele imeko ukuba icace ngokukhawuleza.
Ukuqinisekiswa kwe-ESA kunye nohlalutyo lokuqala lwe-meteorite
I-European Space Agency iqinisekisile ngokusesikweni ukuba into ebonweyo yayiyimeteor eyaqhekeka phezu kweNtshona Yurophu.kwaye ubuncinane enye yezo ziqwenga yafika emhlabeni njenge-meteorite, yabetha indlu eKoblenz. Ukusuka apho, amaqela enzululwazi ahlukeneyo avuselelwa ukuba afunde esi siganeko ngokweenkcukacha ezininzi kangangoko kunokwenzeka.
Iqela le-ESA Planetary Defense liqalise ukusebenza ngokutsha kwendlela, isantya, kunye nobukhulu bento leyo. Ngokusekelwe kwiividiyo ezikhoyo, imifanekiso, kunye nedatha yeradar, uqikelelo lokuqala lubonisa ukuba into yokuqala yayiziimitha ezimbalwa kuphela ububanzi—ubukhulu obuncinci, kodwa yanele ukuvelisa ibhola yomlilo emangalisayo.
Imifanekiso yeqhekeza elifunyenweyo, ethathwe imifanekiso nokuba phakathi esitalatweni eKoblenz, ibonisa ilitye elimalunga neesentimitha ezimbalwa.Inembonakalo emnyama kwaye ibonakala ingabonakali emehlweni angaqeqeshwanga. Nangona incinci, iyinto exabisekileyo kakhulu kwisayensi, njengoko igcina ulwazi malunga nemvelaphi kunye nokuguquka kwenkqubo yelanga.
IZiko leeNqwelo-moya laseJamani libonise ukuba, ngokweengxelo zokuqala, i-meteorite isenokuba yi-chondrite.IiChondrites zezona ntlobo zixhaphakileyo zeemeteorite ezinamatye. Ziqulathe iisphere ezincinci zeminerali ezibizwa ngokuba ziichondrules, ezakhiwa malunga neminyaka eyi-4.500 yeebhiliyoni eyadlulayo kwaye zithathwa njengeecapsules zexesha zokwenyani zenkqubo yelanga yokuqala.
Ulwahlulo oluchanekileyo lwe-meteorite kunye nokuqinisekiswa kohlobo lwayo oluchanekileyo kuxhomekeke kuhlalutyo lwe-mineralological kunye neekhemikhali kwilebhu.Olu vavanyo luquka uphando lwesakhiwo salo sangaphakathi, ukwakheka kwe-isotopic, kunye neempawu zemagnethi. Zivumela izazinzulu ukuba zahlule ngokucacileyo ilitye lasemkhathini kwilitye lasemhlabeni kwaye ziphinde zakha izinto ezifana nemvelaphi yalo ngaphakathi kwebhanti ye-asteroid.
Yintoni i-meteor, yintoni i-meteorite, kwaye yenziwa njani i-bolide?
Amagama ajikeleze ezi zinto anokubhida, kodwa igama ngalinye linentsingiselo yalo.I-meteoroid lilitye okanye iqhekeza lesinyithi elihamba esibhakabhakeni, lidla ngokuba lincinci kune-asteroid. Xa le meteoroid ingena emoyeni woMhlaba ngesantya esiphezulu, iyatshisa ngenxa yokungqubana kwaye ibe yi-incandescent, ivelise ukukhanya esikubonayo esibhakabhakeni: oko kukuthi i-meteor.
Ukuba i-meteor ikhanya kakhulu kwaye ikhupha amandla amaninzi, ibizwa ngokuba yi-bolide okanye i-fireball.Yile nto kanye eyabonwa kwisiganeko se-8 kaMatshi phezu kweJamani nakwamanye amazwe angabamelwane. Kwiimeko ezinjalo, kuqhelekile ukuba into iqhekeke ngexesha lokuhla kwayo, ivelise ukukhanya okwesibini kwaye, ngamanye amaxesha, amaza othuko avakalayo ngendlela yokuqhushumba okanye ukuqhuma.
Xa inxalenye yaloo mzimba isinda kwingxubakaxaka enamandla yomoya ize ifikelele emhlabeni, yaziwa ngokuba yi-meteoriteYiloo nto yenzekileyo ngeqhekeza elagqobhoza uphahla lwendlu eKoblenz: lagqiba lonke uhambo, ukusuka kuhambo lwayo lwasemoyeni ukuya ekutshatyalalisweni kokugqibela kwesakhiwo sendlu, laba ngumzekelo ongaqhelekanga we-meteorite ebetha ngqo isakhiwo.
Isazinzulu sejografi yeeplanethi u-Ulrich Köhler, ovela kwiZiko leeNqwelo-moya laseJamani, uchaze ukuba iinkwenkwezi eziqhelekileyo ezidubulayo ziluphawu olubonakalayo lwee-meteoroids ezincinci.Ezi zinto zitsha ngokupheleleyo emoyeni kwiindawo eziphakamileyo phakathi kweekhilomitha ezingama-60 ne-110. Zihlala zincinci ngobukhulu kwaye azifiki emhlabeni njengeemeteorite ezibonakalayo.
Ngokwahlukileyo koko, xa into inobukhulu obukhulu, umzekelo obufana nebhola yomnyazi okanye obukhulu, kunzima kakhulu ukuba iqhekeke ngokupheleleyo.Isiganeko esikhanyayo siba qatha ngakumbi, i-meteor iba yi-bolide, kwaye amathuba okuba ezinye iziqwenga ziya kukwazi ukungena emoyeni zize zifikelele kumphezulu ayanda, njengoko kwenzekileyo kwesi sihlandlo eJamani.
Isiganeko esingaqhelekanga eJamani, kodwa asiyonto ingaqhelekanga
Nangona iimpembelelo ezithe ngqo emakhaya okanye ebantwini zinqabile kakhulu, iJamani yayisele ifumene isiganeko esifanayo ngo-2023.Xa iziqwenga ezininzi ze-meteorite zawa kufutshane ne-Elmshorn emantla elizwe, kwafunyanwa iqhekeza elinobunzima obuziikhilogram eziyi-3,7, elithathwa njengelona meteorite linzima kakhulu elifunyenwe eJamani kwiminyaka emalunga nekhulu.
Isiganeko saseKoblenz sijoyina uluhlu olufutshane lweziganeko ezibhalwe kakuhle kwiindawo ezihlala abantu.Oku kugxininisa ukubaluleka kokuba neenethiwekhi zokujonga ezivumela indawo apho iziqwenga ezisandula kuwa khona. Okukhona i-meteorite ifunyanwa ngokukhawuleza, kokukhona itshintshwa kancinci yimozulu kunye nokudibana kwayo nomhlaba, kwaye kokukhona uhlalutyo lwesayensi oluqhutywa kuyo lunokuthenjwa ngakumbi.
Ukufunyanwa kwangoko kweengceba ezimnyama ezifunyenwe ngaphakathi nangaphandle kwendlu echaphazelekileyo Ngokutsho kwe-ESA, oku kubaluleke kakhulu. Iimeteorite ezisandula ukuwa zigcina iikhompawundi eziguquguqukayo kunye nezakhiwo ezibuthathaka ezinokonakala kwiintsuku okanye iiveki ezimbalwa ukuba zichatshazelwe ngamanzi, ukufuma, okanye ungcoliseko lomhlaba.
Ngaphezu koko, eli tyala libangele umdla omkhulu kuluntu nakumajelo eendaba, ngenxa yokuba likhumbuza ezinye iziganeko zamva nje kwihlabathi liphela.Ukunika umzekelo wakutshanje, ngoJuni wonyaka ophelileyo I-meteorite igqobhoze uphahla lwendlu eGeorgia (eMelika), kwaye ngo-2023 umfazi waseFransi watshayiswa yi-meteorite encinci ngelixa wayesela ikofu kwiveranda yekhaya lakhe, engakhange afumane kulimala kakhulu.
Iphephancwadi iSmithsonian libika ukuba isiganeko sase-Alabama sika-1954, apho i-meteorite yabetha u-Ann Elizabeth Hodges ecaleni ngelixa wayelele.Iseyeyona meko ibhalwe kakuhle yokuba umntu wachaphazeleka ngokuthe ngqo. Ngethamsanqa, isiganeko saseJamani asizange sibe nazintlungu, kodwa sidibana nolu thotho lweziganeko ezibonisa ukuba, nokuba kubonakala kungenakwenzeka kangakanani, amatye asesibhakabhakeni ngamanye amaxesha adibana nobomi bethu bemihla ngemihla.
Ukhuseleko, imitha kunye neengcebiso xa kukho i-meteorite esandul' ukuwa
Omnye wemibuzo yokuqala ephakamayo xa i-meteorite ibetha indawo ehlala abantu kukuba ingaba ibeka umngcipheko we-radiological okanye we-chemical.EKoblenz, abacimi-mlilo bathathe imilinganiselo yemitha yenyukliya kunye nezinto ezinokuba yingozi kwindawo yengozi, kwaye kuzo zonke iimeko amaxabiso ajika abe aqhelekileyo.
Iingcali zigxininisa ukuba uninzi lweemeteorite azinazo ii-radioactive kwaye azinazo izinto ezinobuthi ezibeka umngcipheko ngoko nangoko kuluntu.Ngokwenyani, ngamatye okanye imixube yelitye nesinyithi ebehamba esibhakabhakeni kangangeebhiliyoni zeminyaka, yenziwe ikakhulu zii-silicates, isinyithi kunye ne-nickel, phakathi kwezinye izimbiwa.
Nangona kunjalo, isazinzulu ngejografi u-Ulrich Köhler ugxininisa ukuba akuyonto ilungileyo ukuchukumisa i-meteorite esandula ukuwa ngezandla ukuba uceba ukuyifunda ngokwesayensi.I-asidi ekujulukeni komntu inokusabela kumphezulu we-meteorite, itshintshe ukwakheka komphezulu wayo kwaye ichaphazele iziphumo zohlalutyo olulandelayo, ingakumbi malunga neekhompawundi eziguquguqukayo kunye nemikhondo yeekhemikhali ezibuthathaka.
Ngenxa yeso sizathu, xa ukrokrela ukuba ilitye lisenokuba yimeteorite Xa sele iwile, eyona nto ilungileyo kukungayisingathe ngqo.Yazisa abasemagunyeni okanye amaziko ezenzululwazi, kwaye ukuba kuyimfuneko ukuyiqokelela, yenza njalo ngeeglavu okanye izixhobo ezinciphisa ukudibana ngqo. Oku kuqinisekisa ukuba izinto ezisetyenzisiweyo zigcina "ubunyulu" obukhulu kangangoko kuhlalutyo lwelabhoratri.
Ngokwembono yomthetho, iimeteorite ezifunyenwe eJamani zihlala zithathwa njengempahla yomntu ofumene le mifanekiso, ngaphandle kokuba kuchazwe ngenye indlela.UKöhler uthi, ngokubanzi, nabani na ofumana i-meteorite angayigcina, nto leyo eyenza ezi zinto zifunwa kakhulu ngabaqokeleli kunye neemyuziyam, nangona izazinzulu zihlala zikhuthaza ukuba zinikwe okanye zibolekwe ukuze zihlalutywe.
Zingaphi izinto ezingaphandle komhlaba eziwela eMhlabeni kwaye zeziphi iingozi ezibangela oko?
Umbono wokuba isiganeko sikaKoblenz siyinto engaqhelekanga uhambelana nenyaniso ephawulekayo: Umhlaba ufumana ngaphezulu kweetoni ezingama-50.000 zezinto ezingaphandle komhlaba minyaka le.Ngokutsho kophando olwenziwe yingcali yeenkwenkwezi uChristian Gritzner we-Institute of Aerospace Engineering eDresden, uninzi lwale nto lufika lukwimo yothuli kunye namasuntswana amancinci aqhekekayo emoyeni.
Izinto ezingaphantsi kweemitha ezingama-30 ububanzi zihlala zitshatyalaliswa ngokupheleleyo ngaphambi kokuba zifike emhlabeniNangona zinokuvelisa iibhola zomlilo ezimangalisayo, kwaye kwiimeko ezithile, amaza othuko anamandla okwenza umonakalo ongathanga ngqo, njengeefestile eziqhekekileyo, ziingceba ezomeleleyo nezinkulu kuphela ezikwaziyo ukungena emoyeni ngaphandle kokudilika ngokupheleleyo.
Umzekelo ogqithisileyo wemiphumo ye-bolide enkulu yayisisiganeko saseChelyabinsk eRashiya nge-15 kaFebruwari 2013.Ngeso sihlandlo, into enobubanzi obuziimitha ezingama-20 kwaye inobunzima obuziitoni ezili-13.000 yaqhuma kumgama omalunga neekhilomitha ezingama-30, ikhupha amandla alingana neebhombu ezininzi zeathomu ezifana neyaseHiroshima.
Izaqhwithi ezisuka eChelyabinsk zaphula iifestile kwizakhiwo ezingamawaka zaza zalimaza abantu abamalunga ne-1.500.Uninzi lomonakalo lubangelwe ziingceba zeglasi. Nangona kunjalo, i-meteorite ayizange ibethe umphezulu njengeqhekeza elinye, kodwa yaqhekeka emoyeni, nto leyo eyanciphisa kakhulu umonakalo onokubakho owawunokubangelwa yimpembelelo ngqo.
UGritzner uphinde wabala amathuba okuba i-meteorite ibethe umntu ngokuthe ngqo.Xa kujongwa imilinganiselo efana nommandla womhlaba, ubuninzi babantu, inani eliqikelelweyo lamatye asesibhakabhakeni awela minyaka le, kunye nobude bobomi bomntu, isiphumo siyaqinisekisa: amathuba aphezulu aqikelelweyo linye kwizigidi ezili-174.
Kutheni singenakuzibona ezi zinto zisiza: ukusilela kunye nemida yeenkqubo zokujonga
Enye yezona zinto ziphazamisayo ngesiganeko saseKoblenz kukuba into ebangela oku ayizange idweliswe kwiikhathalogu ezinkulu zokujonga indawo.I-ESA ibonise ukuba ixesha lokubetha kunye necala lokufika kwayo libonisa ukuba i-meteoroid mhlawumbi yayingabonakali kwiiteleskopu eziqhelekileyo zophando, ngokuyinxenye ngenxa yokuba yayisondela kwindawo yesibhakabhaka xa ilanga lisondela, ekhanya ngakumbi kwaye kunzima ukuyijonga.
Enyanisweni, oku kuthetha ukuba umzimba oneemitha ezininzi ububanzi ungene emoyeni ngaphandle kokuba ubonwe ngaphambili.Oku akuyonto ingaqhelekanga. Ukuza kuthi ga ngoku, zilishumi elinanye kuphela izinto zendalo ezinjalo ezichongiweyo ngaphambi kokuba zingene, inani eliphantsi kakhulu xa ucinga ngobungakanani bezinto ezihambayo kufutshane noMhlaba.
Inethiwekhi ye-AllSky7 yaseYurophu kunye nezinye iinkqubo zokufumanisa ngokuzenzekelayo zenze umsebenzi omhle wokurekhoda esi siganeko xa i-meteor sele ingenile emoyeni.Kodwa oko akuthethi ukuba ukubhaqwa kwangoko kunye nokukwazi ukuqikelela. Ngaphezu kwako konke, ziinethiwekhi zoxwebhu kunye nophando, azizizo iinkqubo zokulumkisa ezibonelela ngezilumkiso kwiintsuku okanye iiyure kwangaphambili.
I-ESA ngokwayo iyavuma ukuba izinto eziphakathi, ezifana neyabangela iKoblenz meteorite, kunzima kakhulu ukuzilandela.Zincinci kakhulu ukuba zingabonwa ngokulula njengee-asteroid ezinkulu ezinokuba yingozi kwiplanethi, kodwa zinkulu kakhulu ukuba zingabonwa ukuba zingena emoyeni kufutshane neendawo ezihlala abantu.
Ezi ntlobo zeziganeko zivuselela ingxoxo malunga nesidingo sokuphucula iinkqubo zokhuselo lweeplanethi, ngakumbi, ukwandisa ukubekwa esweni kwamatye ngobukhulu obuziimitha ezimbalwa.Ezi rokhethi ziyakwazi ukuvelisa iibhola zomlilo ezimangalisayo, kwaye ngamanye amaxesha, zichaphazela ngqo izakhiwo okanye iziseko zophuhliso. Unxibelelwano phakathi kweearhente zasesibhakabhakeni, ii-observatories, kunye neenethiwekhi zeenkwenkwezi ezingengomdyarho lubalulekile ekwenzeni inkqubela phambili kule ndawo.
Iprojekthi yeFlyyeye kunye "nekhaka" lesithuba laseYurophu.
Ukuphendula le mingeni, i-ESA iphuhlisa iprojekthi yeFlyyeye, iteleskopu yophando enembono ebanzi kakhulu.Iphefumlelwe yindlela ezimile ngayo izinambuzane, injongo yayo kukujonga iindawo ezinkulu zesibhakabhaka ebusuku ngexesha elifutshane, nto leyo eyandisa amathuba okubona izinto ezincinci esingaziboniyo okwangoku.
I-Flyeye yenzelwe ngokuchanekileyo ukuchonga izinto ezifana ne-Koblenz meteoroid, ezinokujongwa kwii-engile ezintsonkothileyo okanye ezikhanyisiweyo. Sekunjalo zinkulu ngokwaneleyo ukuba zivelise iibhola zomlilo kunye neemeteors phezu komhlaba. Ubuchule bazo bokugubungela iindawo ezinkulu zesibhakabhaka buzenza zibe yinxalenye ebalulekileyo "yekhaka" lexesha elizayo laseYurophu nxamnye neengozi zasesibhakabhakeni.
Ingcinga kukudibanisa idatha kaFlyyeye neyezinye iiteleskopu kunye neenethiwekhi zokufumanisa ngokuzenzekelayo ezifana ne-AllSky7.Oku kudala inkqubo edityanisiweyo eyonyusa amathuba okubhaqa amatye anobubanzi obuziimitha ezimbalwa ngaphambi kokuba angene emoyeni. Kwanezilumkiso ezisele zisele iiyure ezimbalwa ngaphambi kokuba zifike zinokuba luncedo ekukhuseleni uluntu.
Kwangaxeshanye, ulwazi oluqokelelwe kwiziganeko ezifana neKoblenz lunceda ekuphuculeni iimodeli zokuqikelela iindlela kunye nokuqhekeka emoyeni.Ityala ngalinye elitsha elibhalwe phantsi ngenqanaba elifanelekileyo leenkcukacha libonelela ngedatha yokwenyani enceda ukuqinisekisa nokuphucula ukulinganisa kwekhompyutha, okubalulekileyo ekucwangciseni amaqhinga okunciphisa iingxaki kwixesha elizayo.
Izazinzulu zikwasebenza ekwakheni kwakhona umjikelo wokuqala wale nto ngaphambi kokuba idibane noMhlaba.Oku kunokunceda ekuqondeni indawo ekuyo ngaphakathi kwenkqubo yelanga, mhlawumbi ibhanti ye-asteroid phakathi kweMars neJupiter. Olu lwazi lunceda ekuqondeni ngcono indlela ezisebenza ngayo izilwanyana ezincinci ezijikeleze iplanethi yethu.
Isiganeko saseKoblenz sele singomnye weziganeko ze-meteor ezibhalwe kakuhle kwiminyaka yakutshanje eYurophu.Ukudibanisa idatha evela kwiikhamera zesayensi, iirekhodi zeradar, iividiyo zabemi, kunye nokufunyanwa ngokukhawuleza kweziqwenga, olu lwazi lupheleleyo luya kuvumela ukucocwa kweendlela zokujonga kunye neendlela zokuphendula kwiimpembelelo ze-meteorite zexesha elizayo.
Xa zizonke, i-meteorite ewela endlwini eJamani ibonisa indlela izinto ezibonakala zikude ngayo, ezifana nezenzululwazi, ezinokuba nemiphumo ebonakalayo kubomi bemihla ngemihla.Nangona amathuba okuba umntu ngamnye abethwe lilitye lasesibhakabhakeni mancinci kakhulu kwaye uninzi lwezi zinto ziyaqhekeka emoyeni, iziganeko ezifana neseKoblenz zisikhumbuza ukuba ukujonga isibhakabhaka nokuphanda iimeteors kunye neemeteorites akuyonto nje yesayensi enomdla, kodwa yinxalenye ebalulekileyo yokhuseleko lwethu lwexesha elide kunye nolwazi lwethu ngendawo yethu kwindalo iphela.
