Inkanyezi edubulayo yinto eye yakhanga isintu kusukela kudala . Abanye abantu baveza izifiso zabo ezijulile noma izifiso zabo kuzo, benethemba lokuthi zizogcwaliseka. Abanye bamane bajabulela ukubuka imvula yezinkanyezi noma ukumamatheka uma, ngengozi, inkanyezi eyodwa idlula esibhakabhakeni ngobusuku obubodwa.
Noma kunjalo, izinkanyezi ezidubulayo ziwumbukwane abaningi bethu abawujabulelayo. Kodwa ziyini? Zivelaphi lezi zinkanyezi ezibonakala zigeleza esibhakabhakeni sethu? Namuhla sizophendula le mibuzo.
Yini inkanyezi edubulayo?
Inkanyezi edubulayo, ngokwesayensi yezinkanyezi, iyinto eyaziwa ngokuthi i-meteor, ekhiqizwa lapho ingxenye encane yezinto ezivela emkhathini (njengothuli noma i-asteroid encane) ingena emkhathini woMhlaba ngesivinini esikhulu. Lapho ingena emkhathini wethu, le ngxenye iyashisa futhi ikhanye ngenxa yokungqubuzana kwezinhlayiya emoyeni okubangelwa isivinini sayo esiphezulu. Lokhu kudala ukukhanya okukhanyayo esikubona ebusuku, esikubiza ngokuthi inkanyezi edubulayo.
Uyini umsuka wokudubula izinkanyezi?
Izinkanyezi eziningi ezidubulayo zivela kuma-comet noma ama-asteroid, njengoba edlula eduze kwelanga, akhipha igesi nothuli, okwenza lokho esikwazi ngokuthi "ifu lezinhlayiya ." Lapho uMhlaba, ekujikelezeni kwawo, udlula kula mafu ezinhlayiya, izingcezu ezincane ezingaphakathi kwawo zingena emkhathini wethu ngesivinini esikhulu. Lapho sibona imvula ye-meteor, ngokuvamile kuba yilapho iplanethi yethu idlula ezingcezu ezishiywe yi-comet. Kodwa i-meteor iba kanjani inkanyezi edubulayo?
Inqubo yokudala ukukhanya esikubonayo
Uma i-meteor ingena emkhathini woMhlaba, ijubane layo lingasukela kumakhilomitha ayi-11 kuya kwangu-72 ngomzuzwana. Lesi sivinini esiphezulu, ebesixoxa ngaso, siyisihluthulelo sokukhanya esikubona ezinkanyezini ezidubulayo. Umoya ophambi kwe-meteor ucindezelwa ngokushesha, okubangela ukwenyuka kwezinga lokushisa. Lokhu kushisa okuphezulu kungashisa i-meteor kufike ku- 1650 degrees Celsius, okubangela ukuthi izinto zishise futhi zikhiphe ukukhanya.
Ishawa ye-Meteor
Izinkanyezi ezidubulayo ngazinye zidonsa ukunaka kwalabo abazibukayo, kodwa imvula yezinkanyezi ijabulisa wonke umuntu. Njengoba kuyimicimbi evamile, kungenzeka ukuhlela ubusuku bokuya uzibone endaweni emnyama (kude nezibani zedolobha) ngobusuku obucacile. Ngemuva kwalokho ungalinda ngokunethezeka, ubheke isibhakabhaka, kuze kube yilapho kuqala umbukiso wemvelo.
Imvula eyodwa edumile kakhulu ye-meteor yi- Perseids, eyaziwa nangokuthi izinyembezi ze-Saint Lawrence. Lesi senzakalo senzeka njalo ngo-Agasti lapho uMhlaba udlula emfucumfucwini eshiywe yi-Comet Swift-Tuttle. Ngaleso sikhathi, singabona ama-meteor afinyelela ku-100 ngehora uma isibhakabhaka sicacile. Ukuze uthole ulwazi olwengeziwe ngalezi zenzakalo, sincoma ukuthi uhlole isihloko mayelana nemvula ye-meteor.
Ezinye izimvula ze-meteor ezidumile zifaka phakathi ama-Geminid , ayenzeka ngoDisemba futhi ahambisana nokukhanya okunemibala; ama-Leonid ngoNovemba, adumile ngoba ama-meteor awo akhiqiza ukuqhuma futhi singabona izinkulungwane ngehora; noma ama-Quadrantid ekuqaleni kukaJanuwari, lawo, nakuba ngokuvamile emfushane, anamandla.
Indlela yokubona i-meteor shower?
Uma unesithakazelo kulezi zinhlobo zemicimbi yemvelo, sifuna ukukunikeza amathiphu okwenza isipiliyoni sakho sokuyibuka sibe ngcono kakhulu. Ngakho-ke phawula ikhalenda lakho lemvula elandelayo bese ulungele ukuyijabulela!
Okokuqala, sidinga ukuthola indawo ecacile enezihlahla eziningi, ukuze sikwazi ukubona isibhakabhaka esikhulu. Le ndawo kufanele ibe kude nemithombo yokukhanya yokwenziwa, okungasivimbela ekubeni sebumnyameni obuphelele futhi kunciphise ukuqina kwesibhakabhaka.
Okungcono kakhulu, kufanele uhambe ngaphandle kokujaha. Ungaletha izihlalo ezigoqekayo, itafula, ukudla okulula—noma yini ezokwenza ukulinda kwakho kube lula futhi kwandise isifiso sakho sokubona izinkanyezi. Ngesikhathi ulindile, kungcono ukubeka izikrini eceleni bese usebenzisa isikhathi sokubuka isibhakabhaka. Ungabheka izinkanyezi ezivame ukubonakala esibhakabhakeni sethu, kodwa unake kakhulu, uzama ukuhlukanisa izinkanyezi noma ukuthola iNkanyezi yaseNyakatho . Kodwa okubaluleke kakhulu, uzovumela amehlo akho ukuba azivumelanise nobumnyama, ukuze abone isibhakabhaka sasebusuku kahle. Ngaleyo ndlela, lapho umbukiso ufika, ungawucabanga ngayo yonke ubuhle bawo. Futhi, okubaluleke kakhulu, uma uthole indawo efanele yokubuka izinkanyezi, yisebenzise njalo uma kunomcimbi okufanele uwubone.
Izinkolelo kanye nezinganekwane mayelana nokudubula izinkanyezi
Kuwo wonke umlando, isibhakabhaka siye sakhanga isintu. Imini nobusuku, besibheka phezulu, sinethemba lemvula noma ukushisa, sifuna indawo yethu, noma simane sijabulele umbukwane omuhle esiwunikezayo, kokubili emini, futhi ikakhulukazi, ebusuku. Izenzakalo ezingaqondakali, lezo ezazibonakala ziwumlingo, bezilokhu zithumba umcabango womuntu.
Emasikweni amaningi, inkanyezi edubulayo yayikholelwa ukuthi iyisibonakaliso sesenzakalo esibalulekile, ngokuvamile into enhle. Yingakho, lapho sibona inkanyezi edubulayo, abanye abantu bethi, "Yenza isifiso." Lesi isiko esisakazeke kabanzi emhlabeni wonke, esisekelwe embonweni wokuthi into edlulayo, edlulayo kangaka, inamandla okuxhumanisa izifiso zethu zobuntu namazulu.
Igama elithi "inkanyezi edutshulwayo" ngokwalo liqala ezikhathini zasendulo, lapho lezi zenzakalo zazicatshangwa ukuthi ziyizinkanyezi eziwa esibhakabhakeni . Kodwa-ke, ngemva kwalesi sihloko, sesiyazi kahle ukuthi ziyini. Nokho, mhlawumbe kufanele sisafise ngazo, 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
