Ukubona iNyanga kwisibhakabhaka esiluhlaza sasemini kunokubonakala kuphikisana: iLanga liphezulu, ngoko kutheni neNyanga ibonakala? Impendulo yeyokuba iNyanga ayidingi bumnyama ukuze ikhanye. Ibonakalisa ukukhanya kweLanga, yaye inokuba ngaphezu komgca womkhathizwe wakho ngoxa neLanga lingaphezu kwawo. Ukuba uyayibona kuxhomekeke kwindawo ekuyo iNyanga, kwisigaba sayo, ekucaceni kwesibhakabhaka nakumahluko phakathi komphezulu oqaqambileyo weNyanga nesibhakabhaka esiyijikelezileyo.
Eyona nto ibalulekileyo ekufuneka uyijonge yi-engile ephakathi kweNyanga neLanga. Le engile iyatshintsha ebudeni benyanga esekelwe kumjikelo weNyanga, itshintshe nendlela ebonakala ngayo iNyanga nexesha losuku ekulungele ukuyibona ngalo. Wakuba uyiqondile le ndlela zikwindawo ngayo, ukubona iNyanga emini akusayi kukumangalisa, yaye uya kukwazi ukuyikhangela ngabom.
INyanga ikhanya ngokwaneleyo ukuze ibonakale
INyanga ayingomthombo wokukhanya njengeLanga. Ukukhanya kweLanga kukhanyisa umphezulu wayo onamatye, kuze okunye koku kukhanya kubonakale kubuyela eMhlabeni. Kwangaxeshanye, isibhakabhaka sasemini sibonakala siqaqambile kuba iimolekyuli zomoya zisasaza ukukhanya kweLanga kumacala amaninzi. Oko kukhanya kusasazekileyo kwenza imvelaphi obona iNyanga kuyo.
Umzekelo oluncedo kukucinga ngento emhlophe qhwa phambi kodonga oluqaqambileyo: isenokubonakala lula ukuba iqaqambe ngokwaneleyo yaye inomphetho ocacileyo. Idiskhi enkulu yeNyanga ebonakala ngathi injalo kunye nomphezulu wayo okhanyiswe liLanga zidla ngokwenza loo mahluko, ngakumbi xa umoya ucacile yaye iNyanga iphezulu ngaphezu komgca womkhathizwe. Inkungu, amafu acekethekileyo nokubengezela kunokunciphisa loo mahluko, ngoxa iNyanga esezantsi isenokubonwa kungqameko olungqindilili lomoya.
Isigaba sibalulekile, kodwa asikokuphela kwento echaphazelekayo. Isikela elibhityileyo linendawo ekhanyisiweyo encinane kuneNyanga esele iphantse yazala, ngoko kunokuba nzima ngakumbi ukulibona kwisibhakabhaka sasemini. Nasesigabeni esiqaqambileyo kunokuba nzima ukuyibona ukuba isondele emgceni womkhathizwe okanye ifiphazwe ngamafu. Kwelinye icala, iNyanga enesiqingatha inokubonakala ngokucacileyo emini xa iphezulu kwisibhakabhaka esingenamafu.
Isigaba sibonisa i-engile ephakathi kweNyanga neLanga
Izigaba zeNyanga azibangelwa sisithunzi soMhlaba. Zibangelwa kukuba iNyanga ijikeleza uMhlaba ngoxa iLanga likhanyisa isiqingatha esinye seNyanga. Xa siyibuka eMhlabeni, sibona ubungakanani obahlukahlukeneyo beso siqingatha sikhanyisiweyo. INyanga entsha iba phantse kwicala elinye neLanga, ngoxa iNyanga epheleleyo iba phantse kwicala elichaseneyo nalo. Kwikota yokuqala neyokugqibela, iNyanga neLanga zibonakala ziqelelene malunga ne-90 degrees esibhakabhakeni, yaye sibona idiskhi ekhanyiswe ngesiqingatha.
Le engile inxulumanisa isigaba nokubonakala emini. Xa iNyanga iyisikela okanye sele iphantse yazala, ayijongani ngqo neLanga, ngoko inokuba ngaphezu komgca womkhathizwe ngeeyure ezithile zasemini. Kwikota yokuqala, iNyanga iba ngasempuma kweLanga esibhakabhakeni; idla ngokuba yinto entle ukuyikhangela emva kwemini, yaye ihlala ibonakala de kube ngokuhlwa. Kwikota yokugqibela, iba ngasentshona kweLanga yaye idla ngokubonakala kusasa. Ixesha elichanekileyo lokuyibona lixhomekeke kumhla nakwindawo okuyo.
Umjikelo opheleleyo ukusuka kwenye iNyanga entsha ukuya kwenye uthatha iintsuku ezingama-29.53059. Ebudeni baloo mjikelo, indawo ekuyo iNyanga iyatshintsha ngokuqhubekayo, ngoko isigaba sikunceda uqonde ubudlelwane bayo neLanga, kodwa asiqinisekisi ukuba iya kubonakala ngexesha elithile. Ukuze ufumane ingcaciso ebanzi ngeemilo ezikhanyisiweyo ezitshintshayo, bona indlela ezisebenza ngayo izigaba zeNyanga.
Ikota yokuqala neyokugqibela ngamaxesha alungileyo okuyikhangela
Xa uqala ukuyikhangela emini, zama kwiintsuku ezingqonge ikota yokuqala okanye eyokugqibela. INyanga ekhanyiswe ngesiqingatha inemilo ebanzi necacileyo, yaye ukwahlukana kwayo neLanga kwenza kube lula ukuyifumana kunesikela elibhityileyo kakhulu. Ikota yokuqala idla ngokulungela ukuyibona emva kwemini nangokuhlwa, kanti ikota yokugqibela idla ngokulungela ukuyibona kusasa okanye kusasa kade. Le yindlela eqhelekileyo, kungekhona ixesha elimiselweyo: umgca womkhathizwe wendawo okuyo, ixesha lonyaka nendawo ekuyo iNyanga zonke zinempembelelo ekubeni ibonakala nini ngaphezu komgca womkhathizwe.
Izigaba zeNyanga esele iphantse yazala nazo zinokuba ngamaxesha alungileyo okuyikhangela emini. INyanga ekhulayo esele iphantse yazala idla ngokuba sesibhakabhakeni emva kwemini, ngoxa iNyanga enciphayo esele iphantse yazala inokubonakala kusasa. Idiskhi ekhanyiswe kakhulu isenokuba lula ukuyibona, kodwa ukuqaqamba kwayo akuqinisekisi ukuba iya kubonakala xa kukho inkungu okanye amafu. Ukujonga kwicala elikude neLanga uze uhlolisise indawo ecacileyo yesibhakabhaka kunokukunceda uyifumane.
Iisikela zinzima ngakumbi ukuzibona. Isikela leNyanga ekhulayo likufuphi neLanga kwisibhakabhaka sangokuhlwa, yaye isikela leNyanga enciphayo likufuphi nalo kusasa. Umgca walo omncinane okhanyisiweyo unokuba mhle kakhulu, kodwa indawo yalo encinane ekhanyisiweyo nokuba kufuphi kwalo nokubengezela kweLanga kwenza kube nzima ngakumbi ukulibona. Ungaze ujonge eLangeni ngeebhayinotyhulasi okanye ngeteleskopu, yaye lumka ngakumbi xa ukhangela isikela elikufuphi neLanga.
Kutheni iNyanga epheleleyo ingafane ibonakale emini emaqanda
Xa iNyanga iphelele, iba kwicala elichaseneyo neLanga esibhakabhakeni. Ngenxa yoko iba ngaphezu komgca womkhathizwe ixesha elininzi ebusuku, iphume xa litshona iLanga ize itshone xa liphuma. Inokubonakala emini kufuphi nala maxesha okuqalisa nokuphela kosuku, kodwa idla ngokuba ngaphantsi komgca womkhathizwe emini emaqanda. Ngoko ukubonakala kwayo iqaqambile akuthethi ukuba iya kubakho kwisibhakabhaka sasemva kwemini esikhanyiswe liLanga.
Xa iyiNyanga entsha, imeko iyachasana: iNyanga iba kufuphi necala elikulo iLanga, yaye icala layo elijonge kuthi alikhanyiswanga ubukhulu becala. Idla ngokufihlwa kukubengezela kweLanga, nangona isenokuba ngaphezu komgca womkhathizwe emini. Isikela elibhityileyo kakhulu emva nje kweNyanga entsha okanye ngaphambi kwayo ngamanye amaxesha linokubonwa xa litshona okanye liphuma iLanga, kodwa kunzima ukuliqaphela. Into ekufuneka ulumkele kakhulu kukuba kufuphi kwalo neLanga, kungekhona nje ukukhanya kwemini.
Yiyo loo nto ukuthi “iNyanga ibonakala emini” kungathethi isigaba esithile kuphela. Izigaba ezininzi zinokubonakala kunye neLanga esibhakabhakeni. Isigaba sikuxelela ukuba ingakanani indawo yecala elijonge kuthi ekhanyisiweyo; umgama we-engile ukuxelela ukuba uyikhangele kude kangakanani neLanga; yaye umgca womkhathizwe wendawo okuyo umisela ukuba iNyanga ingaphezu kwawo na.
Sebenzisa indawo okuyo ukuze ucwangcise ukuyikhangela emini
Ukuze uyikhangele ngendlela ebonakalayo, qalisa ngexesha necala oza kujonga ngakulo kunokuba uqashele. Iideshibhodi zeNyanga zezixeko zikuvumela ukuba ukhethe indawo uze uhlole isigaba sayo sangoku nobungakanani bokukhanya kwayo, amaxesha okuphuma nokutshona kwayo, ukuphakama kwayo ne-azimuth yayo, umgama wayo, kunye nembonakalo yesibhakabhaka nemozulu yalapho. Xa uyijonga emini, ukuphakama kwayo kubaluleke ngokukhethekileyo: iNyanga ephezulu esibhakabhakeni idla ngokubonakala lula kunaleyo ikufuphi nomgca womkhathizwe apho kukho inkungu. I-azimuth ibonisa icala lekhampasi ekuyo, ikuncede ukhangele indawo efanelekileyo yesibhakabhaka ungakhangeli ngaseLangeni.
Nali icebo elisebenzayo: khetha imva kwemini ecacileyo kufuphi nekota yokuqala. Jonga kwideshibhodi yalapho ukuze ubone ukuba iNyanga ingaphezu komgca womkhathizwe na nokuba iya kuba phi esibhakabhakeni, uze ukhangele idiskhi yayo ekhanyiswe ngesiqingatha kwindawo eluhlaza ekude neLanga. Ukuba akuyiboni ngoko nangoko, zama kwakhona xa iphezulu okanye xa amafu nenkungu sele eshukume. Xa ufuna esinye isigaba, sebenzisa ikhalenda yezigaba zeNyanga ukuze ufumane imihla yekota yokuqala neyokugqibela, uze ujonge iimeko zalapho ngexesha oceba ukuyibona ngalo.
Ukukhangela ngokusekelwe kumhla kunokunceda unxulumanise okubonayo nosuku oluthile: isixhobo seNyanga yosuku lokuzalwa sibonisa isigaba seNyanga, ubungakanani bokukhanya kwayo nobudala bayo ngokomjikelo womhla othile. Ezi zixhobo ziphendula imibuzo eyahlukeneyo, kodwa xa uzisebenzisa kunye kwenza kube lula ukuvavanya indlela iNyanga neLanga ezimi ngayo esibhakabhakeni. Eyona nto ibalulekileyo ilula: khangela iNyanga ekhanyiswe ngokwaneleyo ukuze ibonakale, neyikude ngokwaneleyo neLanga ukuze uyifumane ngokukhuselekileyo.
