Izinkanyezi ziyilokho kuthinta okukhethekile okunikeza isibhakabhaka sasebusuku ukubukeka kwaso okuthandekayo nokuyingqayizivele. Inkanyezi ngayinye ikhanya ngokweminyaka noma isigaba sayo sokuphila , ezinye zibonakala kakhulu kunezinye. Uma sibheka lesi sici, umbuzo uphakama: iyiphi inkanyezi ekhanya kakhulu endaweni yonke? Ingabe ikhona evelele kakhulu kunezinye?
Ku-Solar System, iLanga libhekwa njengenkanyezi ekhanya kakhulu uma kuqhathaniswa nezinye eziqondile. Ngenxa yokukhanya kwayo namandla eliwanikezayo, igcina izinga lokushisa elilinganayo phakathi kwamaplanethi ahlukene ohlelweni lwayo. Nokho, kungenzeka yini ukuthi kunenkanyezi ekhanya kakhudlwana? Impendulo ithi yebo. ILanga akuyona yodwa inkanyezi enenhlanhla enokukhanya okukhulu.

Isibonelo esisodwa salokhu ama-quasar amahle kakhulu futhi ahlukile ahlotshaniswa nemigodi emnyama. Ukukhanya okuvela kulezi zimo kukhanya kakhulu, kukhanye kakhulu kunezinkanyezi ezingamakhulu kanye nezinkulungwane zelanga.
Nakuba ingabhekwa njengenkanyezi njengenjalo, akungabazeki ukuthi ukukhanya kwayo kuyinto ethakaselekayo. Inani lamandla aphuma ku-quasar alibaleki, ngakho-ke akukho okulihlula kuleso sigaba.
Ngokuphathelene nesihloko, igama lenkanyezi ekhanya kakhulu endaweni yonke alisho lutho oluqondene nomuntu oyedwa. Namuhla, kunohlu oluhlanganisa abancintisani abahlukahlukene abangakwazi ukubamba leso sihloko.
Ukushiya eceleni iLanga, njengoba ngokokukhanya nebanga yilo elikhanya kakhulu, kunobufakazi babanye abaqhudelana nabo. Ziwuchungechunge lwezinkanyezi ezikhanyisa isibhakabhaka ebusuku ngomfutho omkhulu uma ziqhathaniswa nezinye.
Ngamanye amazwi, uma ubuka usuka eMhlabeni, inkanyezi eyodwa ibhekwa njengekhanya kakhulu kunenye ngokusekelwe ezicini ezithile. Ngakho-ke, akunakwenzeka ukunquma inkanyezi eyodwa njengekhanya kakhulu.
Yiziphi izici ezinquma inkanyezi ekhanya kakhulu endaweni yonke? Ziyini ngempela?
Kuyaziwa ukuthi uMhlaba ukuphela kwendawo okuhlala kuyo ukuthi ukwazi ukubuka izinkanyezi. Ngenxa yalokhu kuguquguquka, imiqondo enjengomkhathi obonakalayo noma umkhathizwe wezenzakalo wendawo yonke iye yasungulwa.
Ngamanye amazwi, yikho konke okungabonakala ngaphakathi kwemingcele yokuqonda kwethu. Ngaphakathi kwendawo yonke ebonakalayo, inkanyezi ekhanya kakhulu iyahlukahluka kuye ngezici ezithile.
Ngenxa yalokho, ayikho into ebizwa ngokuthi inkanyezi ekhanya kakhulu endaweni yonke, noma okungenani ayikho eyodwa, ekhethekile. Ngokuya ngebanga kanye nombono obonwa eMhlabeni, kunesethi ekwazi ukuma ngaphezu kwesinye.
Uma kubhekwa eMhlabeni, ukukhanya kwezinkanyezi kuncike ekukhanyeni kwazo kwangaphakathi kanye nebanga lazo. Isibonelo salokhu yiLanga, inkanyezi engathi uma ibhekwa kwenye indawo ekude ngokulinganayo, ingabonakali ikhanya njengoba ibukeka isuka eMhlabeni.
Ibanga kanye nokukhanya kwangaphakathi
Inkinga enkulu yokubhala inkanyezi eyodwa njengegqame kakhulu endaweni yonke isebangeni layo. Inkanyezi ingaba nokukhanya ngokwedlulele, kodwa empeleni ilungisiswa ngebanga layo eliseduze ukusuka eMhlabeni.
Uma inkanyezi iseduze noMhlaba, izobonakala ikhanya kakhulu , kungakhathaliseki ukuthi ikhanya kangakanani . Ngokuphambene nalokho, uma inkanyezi ikude kodwa ukukhanya kwayo kusamangalisa kakhulu, khona-ke iyinto ethakazelisayo kakhulu.
Nokho, esifuna ukuphetha ngakho ukuthi ukukhanya kwezinkanyezi kulinganiselwe ngokuphelele. Esibhakabhakeni sasebusuku, kuye ngokuthi zikude kangakanani kanye nendawo yoMhlaba, inkanyezi eyodwa izobonakala kakhulu kunenye.
Ngamafuphi… Ingabe ikhona noma ayikho inkanyezi eyodwa ekhanya kakhulu endaweni yonke?

Ngempela, ukusho ukuthi kukhona inkanyezi eyodwa ekhanya kakhulu endaweni yonke kuwukujwayelekile. Noma kunjalo, izinkanyezi eziningana ezikhanya kakhulu ezinomsebenzi ongapheli ziye zabonakala esibhakabhakeni sasebusuku . Okusho ukuthi, ukukhanya kwazo kwangaphakathi kuhlala kungaguquki, futhi ibanga lazo ukusuka eMhlabeni likhulu kakhulu.
Kungase kungabi khona neyodwa inkanyezi ekhanya kakhulu endaweni yonke. Kodwa, okuqinisekile ukuthi kungenzeka ukujabulela okuhle kakhulu okuvela eMhlabeni. Iwuhlu lwamathemba acishe abe yi-100 anezici ezifanelana nesihloko, okulandelayo okugqamayo kuzo.
ISirio
Yaziwa nangokuthi iSirius , iyinkanyezi ekhanya kakhulu eqoqweni lezinkanyezi iCanis Major. Igama layo lesayensi yi-Alpha Canis Majoris, futhi iyinkanyezi enama-binary enokukhanya okungavamile. Esibhakabhakeni esicacile ebusuku, cishe akunakwenzeka ukuphuthelwa.
i-canopus
Ngokwesiko eyaziwa nangokuthi i-Canopus, ingenye yezinkanyezi ezikhanya kakhulu kumlaza we-Carina. Ngalesi sizathu, igama layo lesayensi eliqokiwe i-Alpha Carinae, etholakala ngaphezudlwana nje kweminyaka engu-3000 yokukhanya ukusuka eMhlabeni.
U-Alpha Centauri
Isici esiyingqayizivele se-Alpha Centauri ukuthi iyisimiso esikhanyayo sezinkanyezi ezimbili. Nakuba ibhekwa ngephutha njengenkanyezi eyodwa, umphumela wayo wokukhanya ulandela ukukhanya okuhlangene kwezinkanyezi ezimbili ezimbili. Ngokuvamile, ukukhanya kwayo kukhulu kangangokuthi ayikhanyi ngisho neLanga.
Vega
I-Vega iyinkanyezi eseduze kakhulu noMhlaba enokukhanya okumangalisayo. Iqhele ngeminyaka yokukhanya engu-25 kuphela, iyinkanyezi ekhanya kakhulu eqoqweni lezinkanyezi i-Lyria. Kumphakathi wesayensi, ucwaningo lwayo lungolwesibili kuphela olulandela iLanga ngokubaluleka. Eqinisweni, yake yaba yiNkanyezi yaseNyakatho.
