Ngezinye izikhathi ungabona Izinkanyezi zokudubula ukuwa esibhakabhakeni, bathi uma ubona inkanyezi edubulayo, kufanele wenze isifiso futhi ngokuqinisekile sizofezeka. Ngeso lenyama, inkanyezi edubulayo ibonakala njengokuphazima kwesikhashana kokukhanya okumhlophe. Sikukhombisa okwengeziwe ngalesi sihloko lapha!
Ziyini izinkanyezi ezidubulayo?
Inkanyezi edubulayo, eyaziwa nangokuthi i-meteorite, ayinalutho olufana nenkanyezi, isenzakalo esikhanyayo esihambisana nokungena emkhathini wethu wothuli oluzungeza ku-solar system. Lolu thuli lwesivinini esikhulu luyashisa futhi lukhanye kafushane endaweni yokuphakama ngokuvamile phakathi kuka-70 no-120 km ngaphezu kwezinga lolwandle, ngaphambi kokuhwamuka.
Izinkanyezi ezidubulayo zihambisana nesigaba se-incandescent. Ngokuvamile, i-powder incane (i-millimeter noma ngaphansi kakhulu), kodwa ngezinye izikhathi inkulu futhi ukukhanya kwayo kungathatha isikhathi eside.
Uzibona kanjani kalula?
Ukuze ube nenjabulo yokubuka inkanyezi emangalisayo yokudubula, lezi zincomo ezilandelayo kufanele zicatshangelwe:
Okufanelekile, kufanele ushiye idolobha ubusuku bonke futhi uthole indawo evulekile emaphandleni, ezintabeni, noma olwandle. Kufanele kube yindawo emnyama lapho isibhakabhaka sicwebile. Ukuze uthole ulwazi olwengeziwe mayelana nokuthi ungabuka kuphi, ungathintana Lesi sihloko mayelana nezihlambi ze-meteor.
Ungasebenzisi izibonakude noma izibonakude; ukubuka kuphumelela kakhulu uma kwenziwa ngeso lenyama, njengoba amehlo akho ejwayela ubumnyama nokukhanya kwenkanyezi. Uma ufuna amathiphu amaningi okubuka, ungavakashela Lesi sihloko mayelana ne-2024 Geminids.
Ukubuka izinkanyezi ezidubulayo kungase kungabi ngokushesha kangako, okubalulekile ukuba nesineke ukuze ukwazi ukubona inani elihle lezinkanyezi ezidubulayo. Ukuze ufunde kabanzi mayelana nendlela abaziphatha ngayo, sincoma ukuthi ufunde isayensi ngemuva kokudubula izinkanyezi.
Gwema ukubuka noma imiphi imithombo yokukhanya eseduze ngoba ingalimaza ukubona kwakho ebusuku.
Bavelaphi?
Le mizila yokukhanya emangalisayo ngezinye izikhathi ongayibona esibhakabhakeni ebusuku ibangelwa izingcezwana zothuli namadwala abizwa ngokuthi ama-meteoroid awela emkhathini woMhlaba futhi asha, umzila wokukhanya wesikhashana okhiqizwa i-meteoroid evuthayo Ibizwa ngokuthi i-meteorite.
Ama-Meteoroid aziwa kakhulu njengezinkanyezi ezidubulayo. Uma noma iyiphi ingxenye ye-meteoroid isala ikhanyisiwe futhi empeleni ishaya uMhlaba, leyo ngxenye esele ibizwa ngokuthi i-meteorite. Ngezikhathi ezithile zonyaka, ungase ubone inani elikhulu lama- meteor esibhakabhakeni ebusuku. Ukuze ujule kulesi sihloko, vakashela izinhlobo zamameteorite.
Lezi zenzakalo zibizwa ngokuthi ama-meteor shower futhi zenzeka lapho uMhlaba udlula udoti oshiywe yinkanyezi enomsila ngenkathi. I-Orbit Azungeze ilanga.
Zingabonwa nini?
Izinkanyezi ezidubulayo zivela esibhakabhakeni ikakhulukazi ebusuku basehlobo, ikakhulukazi ngo-August. Amazinga okushisa apholile kanye nokuba khona kwethu phakathi nalesi sikhathi samaholide kwenza kube lula ukukubona. Ukuze uthole ulwazi olwengeziwe mayelana nezinsuku, ungathintana Lesi sihloko mayelana namaPerseids.
Kodwa kungenzeka ukubona izinkanyezi ezidubulayo unyaka wonke, empeleni, kunezinhlobo ezingaba ngu-70 (igama elinikezwe iqembu ngalinye lezinkanyezi ezidubulayo) ezisatshalaliswa phakathi nezinyanga. Eziningi zazo azithakazelisi kakhulu ngoba aziminyene, kepha ishumi nambili lifanelwe ukunakwa.
izinhlobo zezinkanyezi ezidubulayo
Kunezinhlobo ezintathu ezihlukene zama- meteor: lezo ezenziwe ngokuyinhloko ngeqhwa, lezo ezenziwe ngesigaxa sensimbi esiqinile noma esiqinile, nalezo ezenziwe ngezinhlanganisela zekhabhoni ezihlukahlukene.
Lokhu kubangela ukuziphatha okuhluke kancane kuhlobo ngalunye, kodwa akuwona umehluko omkhulu. Ukuze uqonde kangcono izinhlobo ezahlukene, ungathintana .
Enye into ebalulekile i-engeli lapho izinkanyezi ezidubulayo zingena khona emkhathini. Uma ukwi-engeli ecwebezelayo bathola umzila omude esibhakabhakeni futhi ngezinye izikhathi ungabona ngisho nentuthu esele ngemuva, lapho bemmango kakhulu bavame ukukhiqiza ibhande lokukhanya elifushane kakhulu.
Abanye Izinkanyezi ezidlulayo zifika ngokungahleliwe, kodwa ezinye ziwumphumela wenkanyezi enomsila endala osekunezigidi zeminyaka izungeza ilanga futhi isiqala ukuphuka. Lokho kungashiya umzila omude wama-asteroid amancane uMhlaba ovame ukudlula kuwo.
Yini i-meteor shower?
Una i-meteor shower Kulapho ama- meteor, noma izinkanyezi ezidubulayo, zikhanya khona esibhakabhakeni ebusuku, ngokusobala zisuka endaweni efanayo. Izikhathi eziningana ngonyaka, amakhulu ama-fireball akhanyisa isibhakabhaka ebusuku. Lezi zinhlayiya zasemkhathini ezincane zingama-meteoroid futhi ziyimfucumfucu yasezulwini ngokwezwi nezwi. Ukuze ufunde kabanzi mayelana nendlela yokujabulela lesi simo, ungavakashela izithombe zezinkanyezi.
