Inkanyezi edubulayo yinto ekhona ethathekile abantu kusukela njalo. Kunabantu abafaka izifiso noma izifiso zabo ezijulile kubo ngethemba lokuthi bazozenza zifezeke. Abanye abantu bamane bajabulele ukubona imvula yezinkanyezi ezidubulayo noma bamamatheke uma ngenhlanhla ngobunye ubusuku isibhakabhaka siwela eyodwa nje yazo.
Kunoma yikuphi, izinkanyezi ezidubulayo ziwumbukwane abaningi bethu abawujabulelayo. Kodwa Bayini? Injani imvelaphi kulezi zinkanyezi ezibonakala ziwela esibhakabhakeni sethu? Namuhla sizophendula le mibuzo.
Yini inkanyezi edubulayo?
Inkanyezi edubulayo, uma siya emkhakheni wesayensi yezinkanyezi, yinto eyaziwa ngokuthi i-meteorite ekhiqizwa lapho ucezu oluncane lwento evela emkhathini (kungaba uthuli noma i-asteroid encane isibonelo) ingena emkhathini woMhlaba ngesivinini esikhulu. Lapho singena emkhathini wethu, leso siqeshana, Iyashisa futhi icwebezele ngenxa yokungqubuzana Okwenziwa yizinhlayiyana emoyeni ngenxa yaleso sivinini esikhulu. Konke lokhu kubangela lokho kuphazima okukhanyayo esingakubona ebusuku futhi esikubiza ngokuthi inkanyezi edubulayo.
Uyini umsuka wokudubula izinkanyezi?
Izinkanyezi eziningi ezidubulayo zivela kuma-comet noma ama-asteroid okuthi, lapho zidlula eduze nelanga, zikhiphe igesi nothuli, zenze lokho esikwazi ngokuthi. "i-particle cloud". Lapho uMhlaba udlula kulawa mafu ezinhlayiya emzileni wawo, izingcezu ezincane ezingaphakathi kwawo zingena emkhathini wethu ngesivinini esikhulu. Lapho sibona imvula ye-meteor, ngokuvamile kulapho iplanethi yethu idlula izingcezu ezishiywe yizinkanyezi ezinomsila. Manje, i-meteor iba kanjani inkanyezi edubulayo?
Inqubo yokudala ukukhanya esikubonayo
Ngesikhathi i-meteor ingena emkhathini woMhlaba, ijubane layo lingashintshashintshaphakathi kuka-11 no-72 amakhilomitha ngomzuzwana. Lesi sivinini esikhulu kakhulu, esihlala sixoxa ngaso, siyisihluthulelo sezinkanyezi ezidubulayo ukuze zibe nokukhanya. Umoya onalesi siqeshana ngaphambili ucindezelwa kungazelelwe, ukhiqize ukwanda kwezinga lokushisa. Lokhu kushisa okuphezulu kungashisisa i-meteor kuze kubeAma-degree angu-1650 abangela ukuthi izinto zihwamuke futhi zikhiphe ukukhanya.
Ishawa ye-Meteor
Izinkanyezi ezidubulayo ngazinye zidonsa ukunaka kombukeli, kodwa imvula ye-meteor ihlaba umxhwele noma ubani. Njengoba kuyimicimbi evamile, kungenzeka ukuhlela ubusuku ukuze uyoyibona endaweni emnyama (ekude nezibani zedolobha) ngobusuku obucwathile. Ngakho-ke linda ngokukhululeka ubheke esibhakabhakeni kuze kuqale umbukiso wemvelo.
I-meteor shower edume kakhulu "izinyembezi zikaSaint Lawrence", eyaziwa nangokuthi amaPerseids. Lesi senzakalo senzeka njalo ngo-August, lapho uMhlaba udlula imfucumfucu eshiywe yinkanyezi enomsila i-Swift-Tuttle. Ngaleso sikhathi singabona ama- meteor afinyelela kwangu-100 ngehora uma isibhakabhaka sicwebile. Ukuze uthole ulwazi olwengeziwe mayelana nale micimbi, sincoma ukuthi ubuyekeze isihloko mayelana ishawa ye-meteor.
Ezinye izimvula ezidumile AmaGeminids ezenzeka ngoDisemba futhi zibuye zihambisane nokukhanya okunemibala; abakwaLeonids ngoNovemba, edumile ngenxa yokuthi ama- meteor awo akhiqiza ukuqhuma futhi singabona izinkulungwane ngehora; noma ama-Quadrantids ekuqaleni kukaJanuwari okuthi, nakuba ngokuvamile kufushane, kushubile.
Indlela yokubona i-meteor shower?
Uma ukhangwa yilolu hlobo lwezehlakalo zemvelo, sifuna ukukunikeza ezimbalwa izincomo ukuze ulwazi lwakho lokuzibuka lube ngcono kakhulu ngangokunokwenzeka. Ngakho maka ikhalenda lapho izimvula ezilandelayo zizoba nini futhi ulungele ukujabulela ukuzibuka.
Into yokuqala okufanele siyibheke indawo ecacile yezihlahla eziningi, ukuze sikwazi ukubona inani elikhulu lesibhakabhaka. Leyo ndawo kufanele ibe kude nezibani zokwenziwa abantu okuzosivimbela ekubeni sisebumnyameni nesibhakabhaka singabukeki sishubile.
Okuhle ukuhamba kancane, singathatha izihlalo ezigoqayo, itafula, okuthile okudliwayo... noma yini eyenza ukulinda kwethu kubekezeleleke nesifiso sethu sokubona izinkanyezi sikhula. Ngenkathi sisalindile, kungcono ukushiya izikrini eceleni, kahle Thatha ithuba lokubuka isibhakabhaka. Singacabanga ngezinkanyezi ngokuvamile ezisesibhakabhakeni sethu kodwa sizinake, sizama ukuhlukanisa imilaza noma ukuthola imilaza. i-polar Star. Kodwa, okubaluleke kakhulu, sizobe senza amehlo ethu avumelane nobumnyama, ukuthi bayakwazi ukubona isibhakabhaka ebusuku ngokuphelele. Ngakho lapho lo mbukiso ufika, sizokwazi ukucabangisisa ngawo ngabo bonke ubukhazikhazi bawo. Futhi, okubaluleke kakhulu, uma uthole indawo ekahle yokubuka isibhakabhaka, sebenzisa ngokunenzuzo ngaso sonke isikhathi uma kwenzeka okuthile okufanele ukubone.
Izinkolelo kanye nezinganekwane mayelana nokudubula izinkanyezi
Kuwo wonke umlando, isibhakabhaka siye sakhanga umuntu, kungakhathaliseki ukuthi kusemini noma ebusuku, amehlo ayephakanyiswa elindele imvula noma ukushisa, efuna indawo noma ejabulela umbukwane omangalisayo esisinikeza wona emini futhi, ngaphezu kwakho konke, ebusuku. Izigigaba ebezingachazwa, lezo ebezibonakala ziyimilingo Bahlale bewuthatha umcabango womuntu.
Emasikweni amaningi kwakukholelwa ukuthi inkanyezi edubulayo iyona inkomba yesehlakalo esithile esibalulekile, izikhathi eziningi into enhle. Ngakho-ke, lapho sibona inkanyezi idlula, kunabantu abathi: "yenza isifiso". Lesi isiko elisabalele emhlabeni wonke, isiko elisekelwe eqinisweni lokuthi into engapheli, edlulayo, inamandla okuxhumanisa izifiso zethu zobuntu nezulu.
Igama elithi "inkanyezi edubulayo" ngokwalo livela ezikhathini zasendulo, lapho kwakucatshangwa ukuthi lezi zenzakalo zazingeyona into engaphezu kweyodwa. izinkanyezi eziwa esibhakabhakeni. Nokho, ngemva kwalesi sihloko manje sesizazi kahle ukuthi ziyini. Lokho kusho, mhlawumbe kufanele siqhubeke senza izifiso, uma kwenzeka.
Uma ufuna ukwazi okwengeziwe ngezinkanyezi Sincoma ukuthi ubheke izihloko ezilandelayo:
- Uyazi ukuthi iyini inkanyezi ekhanya kakhulu endaweni yonke?
- Uyawazi ama-draconids? Thola isizathu sokunye kwezihlambi ze-meteor ezinhle kakhulu!
- Yiziphi izinhlelo zokusebenza ezingcono kakhulu ongazibona izinkanyezi?
- Yazi konke okudingayo ukuze uzuze izithombe zenkanyezi
