izinhlobo zokusitheka kwelanga

inyanga emboze ilanga

Selokhu kwathi nhlo, abantu bebelokhu bethakaselwa ukufiphala kwelanga. Ziyizigigaba ezenzeka kuyaqabukela kodwa zinobuhle obukhulu. Kukhona ezahlukene izinhlobo zokusitheka kwelanga, ngaphezu kwalokho abantu abakucabangayo, njengoba lehliselwa ekusithekeni kwelanga nasekusithekeni kwenyanga. Nokho, kunezinhlobonhlobo eziningi.

Kulesi sihloko sizokutshela ngezinhlobo eziyinhloko zokusitheka kwelanga ezikhona, izici nokubaluleka kwazo.

yini ukusitheka kwelanga

uhlelo lokusitheka kwelanga

I-solar eclipse isenzakalo sezinkanyezi lapho ukukhanya okuvela emzimbeni we-incandescent, njengelanga, kumbozwe ngokuphelele noma ingxenye enye into e-opaque endleleni (ebizwa ngokuthi i-solar eclipse), isithunzi sayo siphonswa emhlabeni.

Empeleni, ukusitheka kwelanga kungenzeka phakathi kwanoma yiliphi iqembu lezinkanyezi inqobo nje uma amandla okuguquguquka okukhulunywe ngawo ngenhla kanye nokuphazamiseka kokukhanya kwenzeka. Nokho, njengoba bengekho ababukele ngaphandle koMhlaba, sivame ukukhuluma ngezinhlobo ezimbili zokufiphala kwelanga: ukufiphala kwenyanga kanye nokusitheka kwelanga, kuye ngokuthi iyiphi indikimba yasezulwini efihliwe.

Ukufiphala kwelanga kuye kwathakazelisa futhi kwaphazamisa abantu kusukela kudala, futhi impucuko yethu yasendulo ibone izimpawu zoshintsho, inhlekelele, noma ukuzalwa kabusha ekusithekeni, uma kungenjalo amabika ngaleso sikhathi. njengoba izinkolo eziningi zikhulekela ilanga ngandlela thize.

Nokho, lezi zigigaba zaziqondwa futhi zabikezelwa impucuko yasendulo enikezwe ulwazi lwesayensi yezinkanyezi ngenxa yokuthi zacwaninga ukuvela kabusha kwemijikelezo yezinkanyezi emakhalendeni ahlukahlukene. Abanye babo baqala ukuzisebenzisa ukuze bahlukanise izinkathi zezombangazwe, zenkolo noma zezenhlalo noma izinkathi.

Kungani kwenzeka ukufiphala kwelanga?

izinhlobo zokusitheka kwelanga

Ngesikhathi sokusitheka kwenyanga, isithunzi esakhiwe nguMhlaba sifihla iNyanga. I-logic ye-solar eclipse ilula: umzimba wasezulwini umi phakathi kwethu nomthombo othile wokukhanya, okudala isithunzi esivimba ngezinye izikhathi ukukhanya okuningi. Lokhu kufana nalokho okwenzekayo lapho sihamba phezu kwento ephambi kwamalambu e-overhead projector: isithunzi sayo siphinde siphonswe ngemuva.

Nokho, ukuze kube nokusitheka kwelanga, ukuhlangana okunembe kakhudlwana noma okuncane kwezakhi zasemkhathini phakathi kweNyanga, uMhlaba kanye neLanga kufanele kwenzeke, kuphindaphinda inani elithile lemizila. Yingakho zivela nemvamisa ethile.

Ngaphezu kwalokho, zingabikezelwa ngosizo lwamakhompiyutha, isibonelo, ngoba siyasazi isikhathi esisithathayo ukuze uMhlaba uzungeze ilanga ne-axis yalo, kanye nesikhathi esithathayo ukuze inyanga ijikeleze uMhlaba. Phakathi nokusitheka kwelanga, inyanga iphakathi kwelanga nomhlaba.

Ukufiphala kwelanga kwenzeka lapho iNyanga iphakathi koMhlaba neLanga. iphonsa ithunzi layo phezu kwengxenye yobuso boMhlaba, nosuku loMhlaba luvela esithunzini isikhashana.

izinhlobo zokufiphala kwelanga

Ukufiphala kwelanga kungenzeka kuphela phakathi nenyanga entsha, futhi kungenzeka ngezindlela ezintathu ezahlukene:

  • ukusitheka kwengxenye. Inyanga ivimba kancane ukukhanya kwelanga noma ingxenye ebonakalayo yesiyingi sayo, ishiye yonke eminye ibonakale.
  • Eclipse ingqikithi yelanga. Isikhundla seNyanga silungile ukuze endaweni ethile eMhlabeni iLanga libe mnyama ngokuphelele futhi kudalwa imizuzu embalwa yobumnyama bokwenziwa.
  • Ukufiphala kwenyanga. INyanga iqondana neLanga endaweni yalo, kodwa ayilimbozi ngokuphelele, ishiya i-corona kuphela obala.

Ukufiphala kwelanga kuvame kakhulu, kodwa kungabonakala ezindaweni ezithile kuphela phansi ngoba inyanga incane kakhulu kunomhlaba. Lokho kusho ukuthi uhlobo oluthile lokusitheka kwelanga lungabonakala endaweni efanayo njalo ngemva kweminyaka engu-360.

ukusitheka kwenyanga

Ngesikhathi sokusitheka kwenyanga, uMhlaba uphakathi kweLanga neNyanga. Ngokungafani nokusitheka kwelanga, ukufiphala kwenyanga kwenzeka lapho uMhlaba uphakathi kweNyanga neLanga, uphonsa isithunzi sawo eNyangeni futhi wenze kube mnyama kancane, njalo kusukela endaweni ethile phansi.

Ubude besikhathi salokhu kusitheka kwelanga buyahlukahluka, kuye ngokuthi iNyanga ikuphi phakathi kwekhoni yesithunzi esakazwa uMhlaba, ehlukaniswe i-umbra (ingxenye emnyama kakhulu) kanye ne-penumbra (ingxenye emnyama kakhulu).

Kukhona ukusitheka kwenyanga oku-2 kuya ku-5 ngonyaka, okungahle kuhlukaniswe ngezinhlobo ezintathu:

  • Ukufiphala kwenyanga ngokwengxenye. INyanga, ecwile nje ingxenye yesithunzi soMhlaba, ibonakala ifiphele kancane noma ifiphele kuphela ezingxenyeni ezithile zesiyingi sayo.
  • i-penumbral eclipse. Kwenzeka lapho iNyanga idlula esithunzini soMhlaba, kodwa kuphela endaweni ye-penumbral, isifunda esincane esimnyama. Lo mthunzi osabalele usitha kancane umbono weNyanga, noma ungashintsha umbala wayo usuka komhlophe uye kobomvu noma osawolintshi. Kukhona futhi izimo lapho inyanga iyingxenye ye-penumbra kuphela, ngakho-ke kungase kushiwo ukuthi i-penumbral eclipse ingxenye.
  • ukufiphala kwenyanga okuphelele. Kwenzeka lapho isithunzi soMhlaba sifihla ngokuphelele inyanga, okwenzeka kancane kancane, kuqala ukusuka ekusithekeni kwe-penumbral kuya ekusithekeni kwengxenye, bese kuba ukufiphala okuphelele, bese kuba yingxenye, i-penumbral, neyokugcina.

ukusitheka kwe-venusian

Nakuba ngokuvamile singakucabangi njengokufiphala kwelanga okujwayelekile, iqiniso liwukuthi ezinye izinkanyezi zingangena endleleni futhi zihlele phakathi koMhlaba nelanga. Yilokhu okwenzekayo ngalokho okubizwa ngokuthi ukuhamba kweVenus, lapho iplanethi yethu engumakhelwane iphakathi kweLanga noMhlaba. Kodwa-ke, ibanga elikhulu phakathi koMhlaba kanye neVenus uma liqhathaniswa neNyanga yamanje, kuhlangene nosayizi omncane weplanethi uma uqhathaniswa nowethu, kwenza lolu hlobo lokufiphala kwelanga lungabonakali, elimboze ingxenye encane kuphela yelanga lasemhlabeni.

Futhi, ukusitheka kwelanga kwalolu hlobo akuvamile kakhulu futhi kuphindaphinda ngokulandelana: iminyaka eyi-105,5, bese kuba eminye eyi-8, kube eminye iminyaka eyi-121,5, kube eminye eyi-8, emjikelezweni weminyaka engama-243.. Okokugcina kwenzeka ngo-2012, kanti okulandelayo kulindeleke ukuthi kwenzeke ngo-2117.

Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nezinhlobo zokusitheka kanye nezici zazo.
