Impela sesibonile sonke a ukusitheka kwelanga okugcwele noma ingxenye. Lezi zimo zivame ukwenzeka okwesikhashana ngenxa yokujikeleza komhlaba, ukunyakaza kokuhumusha kanye nokuma maqondana nenyanga nelanga.
Kulesi sihloko sizokutshela konke okudingeka ukwazi mayelana nokushona kwelanga okuphelele, okudingeka kwenzeke nokuthi ungakubona kanjani.
Kuyini ukufiphala kwelanga okuphelele
I-solar eclipse isenzakalo lapho iNyanga ibekwe phakathi kweLanga noMhlaba futhi ingakukhansela ngokuphelele, ingxenye noma ukuyichitha, kuye ngobukhulu, indawo kanye nebanga phakathi kwezinkanyezi.
Ngokwesilinganiso, ukufiphala kwelanga kwenzeka njalo ngemva kwezinyanga ezingu-18 futhi kuthatha imizuzu embalwa kuphela. Ukufiphala kwelanga okufanayo kuzothatha iminyaka engu-400 ukuphindaphinda endaweni efanayo eMhlabeni. Lokhu kungenxa yokuthi, njengoba nje umhlaba uzungeza ilanga, inyanga nayo ihamba emzileni wayo oyi-elliptical, kodwa izungeza iplanethi yethu.
Uma umugqa ocatshangelwayo udwetshwa ochaza ukunyakaza kokuhumusha kwendikimba yasezulwini, kungabonakala ukuthi indlela ye-orbit i-elliptical. Ngakho-ke, kuye ngomzila, inyanga iseduze noma iqhelelene nomhlaba, futhi zombili ziseduze kakhulu noma kancane nelanga. Yingakho bengahleli ngendlela efanayo noma ngesikhathi esifanayo sonyaka.
Kungani kwenzeka ukufiphala kwelanga?
Umnyakazo wokuhumusha woMhlaba kanye nesathelayithi yawo yemvelo isho izinguquko ekushubeni kwesithunzi esiyiNyanga Emhlabeni ngesikhathi sokusitheka kwelanga. Lapho inyanga isondela eMhlabeni, ithunzi layo liyaqina futhi libe lincane ububanzi bayo. Ngakho, kukhona ukubhula kwelanga, okungukuthi, ukufiphala kwelanga okuphelele kubonakala kuphela endaweni lapho isithunzi senziwa khona. Kusukela kwezinye izifunda eziseduze okufinyeleleka kuphela yi-penumbra yenyanga, lesi simo sibhekwa njengokufiphala kwelanga okuyingxenye.
Ukuhlola lesi simo ngendlela elula, ibhola lingabekwa phakathi kwesibani nodonga. Ngokusondeza ibhola ekukhanyeni, isithunzi esiphonsa odongeni siba sikhulu futhi sithambile. Ukuhambisa ibhola eduze kodonga kwenza ububanzi besithunzi bube buncane futhi buqine kakhulu.
Uma ibhola kuyinyanga, izindonga amaplanethi futhi ukukhanya ilanga, izimo ezihlukene zokufiphala kwelanga zingalingiswa ngokuhambisa ibhola.
izinhlobo zokusitheka kwelanga
- ukufiphala kwelanga okuphelele Ingabonwa kuphela endaweni ethile yoMhlaba, maphakathi nesithunzi esikhishwe yiNyanga Emhlabeni. Kusuka lapho, kungabonakala ingqikithi yezinkanyezi ezikhanyayo.
- ukusitheka kwengxenye. ILanga lithole ukubhula ngengxenye, okungabonakala endaweni yomthunzi woMhlaba odalwe umthunzi weNyanga. Ungabona inkanyezi ekhanyayo ifihlwe kancane kuyilapho utusa okunye ukukhanya kwayo okumise okwenyanga.
- ukusitheka kwenyanga. Ngokungafani nokufiphala kwengxenye, inyanga ayenzi isithunzi esilifihla ngokuphelele ilanga ngenxa yebanga eliphakathi kwenyanga noMhlaba, kodwa kunalokho yembula i-halo elizungezile.
Izinyathelo zokuphepha zokubheka ukusitheka kwelanga okuphelele
Ukufiphala kwelanga akufanele nanini kubonwe ngokuqondile. Nakuba lokhu kuyisenzakalo esingokwemvelo, kubalulekile ukuthatha izinyathelo zokuphepha ngoba ukulibuka ngokuqondile ilanga isikhathi eside ngosuku oluvamile noma phakathi nokusitheka kwelanga kungabangela ukusha kwe-retina ngisho nokungaboni unomphela. Imisebe eyikhiphayo inamandla kangangokuthi ingalimaza ukubona isikhathi esifushane kakhuluikakhulukazi abancane.
Kukhona izibuko eziklanyelwe ngokukhethekile ukubuka ukusitheka kwelanga ngamalensi anezakhiwo ezifana namamaski wokushisela. Nakuba kubukwa ngamalensi akhethekile, ukubuka ngaphezu kwamasekhondi angu-30 ngesikhathi akunconywa. Kulezi zimo, izibuko zelanga esizigqoka nsuku zonke azisivikeli.
ukusitheka kwenyanga
Ukufiphala kwenyanga kwenzeka lapho uMhlaba uphakathi kwelanga nenyanga, ukushiya inyanga ebumnyameni obuphelele noma ingxenye futhi ingatholi ukukhanya okuvela ezinkanyezini ezikhanyayo.
Ukufiphala kwenyanga kubonakala kuzo zonke izindawo zomhlaba lapho inyanga ibonakala khona, kuyilapho ukufiphala kwelanga okuphelele kungabonakala kuphela endaweni eseMhlabeni lapho inyanga yenza isithunzi. Ngokungafani nokusitheka kwelanga, okuthatha imizuzu embalwa kuphela, kungathatha imizuzu engu-30 kuya ehoreni.
mythos
Ngokuphathelene nombono womuntu, ukusitheka kwelanga akusemuva kakhulu. Lapho abantu bengakwazi ukuchaza lesi sigameko, waqala ukuqamba izindaba mayelana nokuthi ngabe kwenzekile.
Izimpucuko zakuqala zazikholelwa ukuthi zingonkulunkulu abathumela “imiyalezo” ngezinkanyezi. AmaViking athi impisi yashwabadela ilanga futhi yenza imisindo “ukulethusa”. Umphumela uba ukuthi ilanga noma inyanga ibuyela esimweni sayo semvelo, iqinise ngokwengeziwe izinkolelo zakho.
Khona-ke, ezizukulwaneni zanamuhla kakhulu, kwavela izinganekwane, ngaphandle kwencazelo yesayensi, kodwa ezinobufakazi obanele bokuthi zazingenzeka kakhulu. Ngokwesibonelo:
Ukuziphatha kwezilwane akusalawuleki
Akukhona ukuthi ukuziphatha kwezilwane akulawuleki, yilokhu kushintsha okungazelelwe kokusuka ekukhanyeni kuye komnyama, noma okuphambene nalokho, okwenza izilwane ziguqule isigqi sazo sokujikeleza ukuze zivumelane nalokho okwenzeka endaweni yazo.
Phakathi nokusitheka kwelanga okuphelele, singase sibone izinyoni zihlezi ezihlahleni noma ama-raccoon zifuna ukudla. Lokhu kungenxa yokuthi ubumnyama bukutshela ukuthi umsebenzi wakho kufanele uphele noma ungaqala.
Ingane yakho ingase izalwe inezinkinga zempilo
Kuvamile ukuthi abanye besifazane abakhulelwe bagqoke amaribhoni abomvu ukuze bavikele izingane zabo ezingakazalwa ekusithekeni kwelanga. Kuthiwa ngaphandle kwekhasethi, izingane zingazalwa zinokukhubazeka okuthile noma amabala, kodwa kuze kube manje abukho ubufakazi obungokwesayensi bokuthi ucezu lwendwangu lungaxosha noma yiluphi uhlobo lwamandla e-cosmic.
ungalahlekelwa isisindo
Yiqiniso, kodwa hhayi kuze kube phakade. Amandla adonsela phansi angasivumela ukuba silahlekelwe amagremu angu-500, amagremu angu-700 noma ikhilo elilodwa, kodwa lapho izinkanyezi ziphindela ezihlukene, lokhu kuzobuyela esimweni esivamile.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokusitheka kwelanga okuphelele nokuthi yiziphi izici zakho.
