Unyaka wonke, ukususela ngoJanuwari ukuya kuDisemba, Iimvula ezimangalisayo zemeteor zenzeka. Ziziganeko zeenkwenkwezi ezikufanele ukuphila kube kanye ngexesha lobukho. Phakathi kwazo zonke iindidi ezikhoyo, enye yeeshawari zemeteor ezibetha kakhulu ziidrakoni ezingaqhelekanga.
Ngokwenyani, zezinye zezona mvula zibalaseleyo zemeteor eziwela unyaka wonke. Uvela ekuqaleni kuka-Okthobha, ukwandisa ngaphezu kweveki enye esibhakabhakeni ebusuku. Ngokunjalo, zibonakaliswa ngokuqaqamba okungaqhelekanga, kunye nokumila okunomtsalane ngakumbi kunye nokufuduswa xa kuthelekiswa nezinye iishawari zemeteor.
Unokuba nomdla kwinqaku lethu: Kutheni kwenziwa ishawari yeemeteor?
IiDraconids kunye nomboniso wabo othakazelisayo esibhakabhakeni sasebusuku
Iishawari zemeteor ziziganeko ezinomdla zeenkwenkwezi ezenzeka ngamaxesha onyaka onyaka. Ukuqala kwinyanga kaJanuwari, ixesha lonyaka ngalinye liphawulwa ngohlobo lwemvula. Xa ikwindla ifika, yi-draconids ejongene nokuhlobisa isibhakabhaka ebusuku. Ziyabonakala kwiindawo ezithile okanye kwimimandla yehlabathi, logama nje kungekho ngcoliseko yokukhanya kakhulu.
Nangona bengaqatshelwanga njengokwandulelayo, olunye uhlobo lweshawari yeemeteor, nazo ziyamangalisa kwaye zinika umdla. Banomgangatho wokushiya umzila obanzi kunye oqaqambileyo ngenyathelo labo elidlulayo.
IiDraconids zityala imvelaphi yazo ngokukhazimla, oko kukuthi, indawo ebonakalayo apho imvula isuka khona. Oku kuhambelana ngokuthe ngqo kunye neenkwenkwezi zeDraco okanye i-Dragon, ngoko zibizwa ngokuba zisekelwe kuyo.

Kwakhona, kufuneka kucaciswe ukuba, enyanisweni, ngokoqobo azizonkwenkwezi ezibonwa esibhakabhakeni. Endaweni yoko, ngamaqhekeza, inkunkuma, okanye uthuli oluvela kwicomet enkulu njengoko yayidlula emhlabeni.
Le nkunkuma eshiyekileyo evela kwi-comet, xa idibene nomoya, ivutha ngokukhawuleza, ivelise isiphumo esele saziwa. Umahluko kuphela ngeenkwenkwezi ezidubulayo kukuba sisiganeko esikhulu. Oko kukuthi, ukukhetheka okunjalo kunokuthakazelelwa ngalo lonke ixesha lesi siganeko.
Ivela phi le meteor shower? I-comet ehambelana ne-Draconids ibambe impendulo!
IiDraconids, nangona zingaziwa kangako njengezinye iintlobo zeeshawa zasemeteor, Ziyenye yezona zininzi. Enyanisweni, malunga nekhulu leminyaka edlulileyo, kwi-1933, i-meteor shower ukuya kwi-345 / min yabhalwa. Ngaphandle kwamathandabuzo, xa kufikwa kubuninzi kunye nokubonisa, bayinxalenye yeqela elibalaseleyo.
Ukuxabisa olu hlobo lokuhlamba i-meteor luhamba kunye ne-comet ehambelana ne-Draconids. Nyaka ngamnye, amaqhekeza alo mmandla wesibhakabhaka udlulayo adibana nomoya ojikeleze umhlaba, ekhuthaza esi siganeko.
Ngokukodwa, kwenzeka phakathi kweentsuku zokuqala zika-Oktobha, ngobuncinci ukusuka kwi-6 kunye nobuninzi ukuya kwi-10 kwinyanga efanayo. Ngesi sizathu, zikwachazwa njengomgangatho wokuba yenye yezona mvula zide zemeteor.
Comet 21P/Giacobini-Zinner
I-comet enxulumene ne-Draconids inikwe igama layo kubavumbuzi bayo, UMichel Giacobini y U-Ernst Ziner. Bobabini babengabokuqala ukujonga i-orbit yale comet kunye nobudlelwane bayo obuthe ngqo noMhlaba.
Into engaqhelekanga ehambelana nale comet kukuba, ngamaxesha ngamaxesha, umjikelo wayo uxabiseke ngakumbi ukusuka eMhlabeni. Ngokuqhelekileyo, ekuqaleni kokuwa, kunokwenzeka ukubona ukubonakala kwale comet.
Kodwa eyona nto imangalisayo ngayo kukuba ukuvuka kwayo kushiya ngasemva indlela yamaqhekeza, umkhenkce nothuli. Ngenxa yokuba kufutshane noMhlaba, le nkunkuma idibana nomoya ojikeleze umhlaba, ivelise isiphumo semvula enkulu.
Ngamafutshane, umoya utshisa ngokupheleleyo yonke inkunkuma encinci engena, inika imbonakalo eqhelekileyo yemvula yeenkwenkwezi. Ngenxa yesi sizathu, zikwabizwa ngokuba yimvula yeemeteor, kuba, ngokuqinisekileyo, yiyo.
Ngaphakathi kolandelelwano lweengcinga ezifanayo, eyona ndlela ingcono yokufumana imvelaphi yale meteor shower kukukhazimla kwayo. Ngokunjalo, kufuneka kuthathelwe ingqalelo into yokuba kunokwenzeka ukuba zibonwe kwihemisphere esemantla nakwi-ikhweyitha.
ukukhanya, ayisiyonto ngaphandle kwendawo ebonakalayo okanye umkhondo, Isuka phi le meteor shower? Ngesi sihlandlo, ukukhanya kweeDraconids kuhambelana neenkwenkwezi zeDragon, ngenxa yegama layo.
Eyona ndlela ilungileyo yokujonga ishawari ye-Draconid meteor kukulandela la macebiso

Njengoko kukhankanyiwe ngasentla, iDraconid Meteor Shower ayaziwa njengezinye. Nangona kunjalo, kuyafaneleka ukuphila amava esi siganeko kungakhathaliseki ubukhulu bentlalo obumele. Ukwenza oku, uluhlu lweengcebiso lubonakala lufanelekile oluya kuba negalelo ngokuthe ngqo ekufumaneni isiphumo esihle.
indawo kunye nemozulu
Ukujonga ishawa yemeteor ngokubanzi, indawo ekude nesixeko kufuneka ikhethwe. Okukhona kukho ungcoliso lokukhanya, kokukhona kukhula ubunzima bokusixabisa esi siganeko seenkwenkwezi.
Ngokunjalo, imozulu ichaphazela i-equation ngokulinganayo. Ngoko ke, kuyimfuneko ukuba ube nokukhanya kwenyanga kunye nesibhakabhaka esicacileyo ukuze uphile amava ngokupheleleyo. Ngamafutshane, akusiyo indawo kuphela, kodwa nobusuku kunye nomzuzu.
izixhobo zobuchule
Ukujonga i-Draconid Meteor Shower kubandakanya ukusetyenziswa kwezixhobo zobuchule. Kanjalo, Isixhobo sebhayinotyhulasi okanye isibonakude siyafuneka ukwandisa indawo yokujonga ngokwayo. Ezo zixhobo ziyilelwe ukuvelisa ugqaliselo olululo okanye ulwandiso, olukwaziyo ukunika umsebenzisi indawo yombono enenzuzo.
Indawo yemvelaphi
Inyaniso ebalulekileyo ekufuneka iqwalaselwe kukuba akunakwenzeka ukujonga imvula yeenkwenkwezi kuzo zonke isibhakabhaka. Ngokuqhelekileyo, ngokubhekiselele kwiiDraconids, zibonakala kakhulu kwi-hemisphere esenyakatho kunye ne-equatorial zone. Ngaphandle koko, kuya kuba nzima kakhulu ukonwabela lo mboniso wasebusuku.
