Kwenzeka nini ukusitheka kwenyanga?
Isithunzi seNyanga sihlukaniswe ngezindawo ezimbili: i-umbra, noma isithunzi, okuyingxenye emnyama, efana nekhoni, kanye ne-penumbra, okuyindawo ezungezile. Ngakho-ke, ukufiphala kwenyanga kungenzeka kuphela ngesikhathi senyanga egcwele ukuze, lapho izidalwa ezintathu zasezulwini (okukhulunywe ngazo ngenhla) ziqondane, iNyanga ingena ekhonini lesithunzi eliqondiswe eMhlabeni lisuka emkhathini. Lesi simo singenye yezici eziningi ezithakazelisayo zeNyanga njengesathelayithi . Kulabo abafisa ukufunda kabanzi ngezinhlobo ezahlukene zokufiphala, ungabheka "Zingaki izinhlobo zokufiphala ezikhona?".
Ngokufanayo, into yokuqala ethokozisayo ukuqagela ukuthi ukufiphala kwelanga kufanele kwenzeke njalo ngenyanga ngenyanga egcwele, kodwa lokhu akunjalo ngoba umjikelezo wenyanga ugobile maqondana nendiza ye-ecliptic (umugqa onama-arced lapho iLanga "lidlula khona" eduze koMhlaba , "kugesi walo ongokomfanekiso" obonwa eMhlabeni).
Ukumelwa kwesenzakalo sokufiphala kwenyanga
Ngokungafani nokufiphala kwelanga, okubonakala kuphela engxenyeni ethile yoMhlaba, ukufiphala kwenyanga kungabonakala kunoma iyiphi indawo eMhlabeni lapho kusebusuku khona. Ngakho-ke, ukufiphala kwenyanga kungahlala amahora amaningi, kuyilapho ukufiphala kwelanga kubonakala imizuzwana embalwa kuphela. Ukuze ufunde kabanzi ngomehluko phakathi kokufiphala kwelanga, ungabheka ukuhlukaniswa ku-[link to classification], kanye nokubaluleka kokufiphala kwelanga ku- astronomy yamaMaya . Ukuze uthole ulwazi olwengeziwe ngezinye izenzakalo zezinkanyezi, iya ku -astronomy phenomena yalo nyaka.
Ngomqondo othile, kubalulekile futhi ukuveza ukuthi singabona ukufiphala kwenyanga ngqo, ngama-binoculars noma nge-telescope ; kuyilapho ukufiphala kwelanga kumele kubhekwe ngokuvikelwa kwamehlo.
super blue blood moon phenomenon
Leli gama libhekisela enyangeni egcwele, eyenzeka lapho inyanga iseduze kakhulu nomjikelezo wayo womhlaba. Ososayensi bakhomba ukuthi umjikelezo wenyanga mude kakhulu, futhi izinyanga ezigcwele zihambisana nokusondela kwayo eplanethini yethu. Baphawula nokuthi lesi simo senzeka nyanga zonke; inyanga isondela futhi iqhelelene noMhlaba njengoba ilandela umjikelezo wayo. Kodwa-ke, uma le ndlela eseduze kakhulu ihambisana nenyanga egcwele, ibizwa ngokuthi i-supermoon. Ukuze uthole ulwazi olwengeziwe mayelana nezinyanga zegazi, vakashela i-Blood Moon , njengoba ihlobene kakhulu nokufiphala kwenyanga.
Ngakho-ke, umjikelezo weNyanga u-elliptical, kanti uhlangothi olulodwa luqhele ngamakhilomitha angaba ngu-50.000 ukusuka eMhlabeni kunolunye, indawo eseduze kakhulu, eyaziwa ngokuthi i-perigee. Ngaphezu kwalokho, abacwaningi bathi lapho iNyanga ibonakala inkulu ngo-10 kuya ku-15% kunokuba ibingabonakala ngesikhathi esifushane, ushintsho luyabonakala kakhulu ngokuyibuka nje. Ngaphezu kwalokho, le supermoon izoba yinyanga yesibili egcwele ebonwe ngoJanuwari walo nyaka.
Olunye uphenyo olumayelana nenyanga yegazi
Labo ababone ukufiphala kwelanga bakwazi ukubona iNyanga enkulu ebomvu, evame ukubizwa ngokuthi iNyanga Egazi . Kulokhu, umbala weNyanga ngesikhathi sokufiphala kwelanga okuphelele ubangelwa umkhathi weplanethi yethu. Yingakho, ukube besiseNyangeni ngaleso sikhathi, besizobona uMhlaba udlula phambi kweLanga. UMhlaba uvela njengesondo elimnyama, kodwa khumbula ukuthi uMhlaba unesimo sezulu, futhi ukukhanya okudlula emkhathini bese kuhamba kuya eNyangeni kuyaphambuka. Ngaphezu kwalokho, lesi simo siyisibonelo...
Ngale ndlela, ingxenye ebomvu yokukhanya kwelanga ifinyelela eNyangeni. Ukube besiseNyangeni, besizobona umbala ofanayo nokushona kwelanga. Kodwa kulokhu, bekuyoba ukuhwalala kwelanga, okuzovela njengendandatho ebomvu eduze koMhlaba, futhi lokho kukhanya okukhanyisa iNyanga, yingakho kubonakala kubomvu. Kulabo abanesifiso sendlela yokutadisha izinkanyezi enobungane nezingane, kunezinsiza ezitholakala ku- Astronomy for Kids.
Ukusabalala kokukhanya yikho okubangela ukushona kwelanga okubomvu eMhlabeni. Futhi lesi simo asihlobene nhlobo nendlela ukukhanya okuhamba ngayo, kodwa kunalokho sihlobene ne-engeli lapho imisebe yelanga ibuyela khona kithi.
Ngakolunye uhlangothi, uma kwenzeka ukushona kwelanga okubomvu, okwenzekayo ukuthi kunezinto ezisemkhathini weplanethi yethu, ikakhulukazi amanzi, i-nitrogen, kanye nomoya-mpilo. Lawa ma-molecule asakaza ukukhanya okuluhlaza okwesibhakabhaka, yingakho isibhakabhaka sinombala oluhlaza okwesibhakabhaka emini. Ngokufanayo, lapho ilanga lishona noma ngaphambi kokuphuma kwelanga, ukukhanya okubomvu kuyabusa ngaleso sikhathi ngoba ukukhanya okudlula kalula emkhathini . Okokugcina, abacwaningi bathi ngesikhathi esilandelayo lapho lezi zimo ezingavamile zihlangana khona kuzoba eminyakeni eyi-19, ikakhulukazi ngoJanuwari 31, 2037.
3 izenzakalo zenyanga
Ngale ndlela, isenzakalo sokufiphala kwenyanga singahlukaniswa kanje:
ingxenye yokusitheka kwenyanga
Kulesi simo, ingxenye eyodwa kuphela yeNyanga ezofihlwa . Ukuze uthole ulwazi olwengeziwe mayelana nokuhlukaniswa kokufiphala kwelanga, sicela ubheke [isixhumanisi/ireferensi].
isenzakalo sokufiphala kwenyanga ngokuphelele
Ngakolunye uhlangothi, ukuze kwenzeke ukufiphala kwenyanga okuphelele, lonke ubuso besathelayithi yethu yemvelo kumele bungene ekhoneni lomthunzi woMhlaba , futhi lokhu kwenzeka ezinhlotsheni ezahlukene zokufiphala. Uma ungathanda ukufunda kabanzi ngezinhlobo zokufiphala, ungabuyekeza isenzakalo sokufiphala kwenyanga.
isenzakalo se-penumbral lunar eclipse
Lapha, iNyanga ingena ekhoneni lomthunzi woMhlaba. Kubalulekile ukuqaphela ukuthi ubude kanye nohlobo lokufiphala kwelanga kuzoncika ekuqondeni kweNyanga uma kuqhathaniswa nokudlidliza kwayo okuzungezayo.
Ubuwazi?
Ngokungafani nokufiphala kwelanga, okungabonakala kuphela endaweni encane yoMhlaba futhi kuhlale imizuzu embalwa, ukufiphala kwenyanga kungabonakala noma kuphi eMhlabeni lapho kusebusuku futhi kuhlale amahora amaningi. Lesi ngesinye sezici ezenza kube okukhethekile kangaka. Ungafunda kabanzi ngakho lapha.
Ikhoni yobumnyama nethunzi endaweni yokusitheka kwenyanga
Umjikelezo we -equatorial weLanga mkhulu ngokuphindwe ka-109 kunoweplanethi yethu; ngenxa yalokho, uphonsa ikhoni yesithunzi efanayo kanye nekhoni ye-penumbra ephambene. Ukufiphala kwenzeka ngoba iNyanga, etholakala cishe ngamakhilomitha angu-384,000 ukusuka eMhlabeni, ingena kukhoni yesithunzi soMhlaba, enkulu kakhulu—ngokuqondile, cishe ngamakhilomitha angu-1,384,584 ububanzi.
Ngaphezu kwalokho, ebangeni iNyanga ekude noMhlaba, i-cone yobumnyama inobubanzi obungamakhilomitha angu-9200, kanti ububanzi besathelayithi yethu yemvelo bungamakhilomitha angu-3476. Lokhu kungafani okukhulu kusho ukuthi iNyanga ingangena izikhathi ezingu-2,65 ku-cone yobumnyama, futhi ngenxa yalokho, ukufiphala kwelanga kuhlala isikhathi eside kakhulu esikhathini sazo sonke. Uma ufuna ukuthola okwengeziwe ngezenzakalo zezinkanyezi, ungabheka ku-[link/resource].
Kumuntu osebusweni beNyanga, ukufiphala kwelanga okungaphansi komhlaba kungaba ukufiphala kwelanga okuyingxenye . Ngokufanayo, uma lowo muntu engaphakathi kobumnyama boMhlaba, ubengeke akwazi ukubona ilanga, ngakho-ke kuye, ukufiphala kwelanga okuphelele kungaba khona.
Ngokufanayo, umkhathi woMhlaba udlala indima ebalulekile ekufiphaleni kwelanga. Ngaphandle komkhathi, i-satellite yethu ibingeke iphinde ibonakale ngesikhathi sokufiphala kwenyanga okuphelele (esaziyo ukuthi akwenzeki). INyanga efiphale ngokuphelele iba nombala obomvu ohlukile ngenxa yokukhanya okuguqulwa umkhathi weplanethi yethu . Isikali se-Danjon sisetshenziselwa ukubala izinga lobumnyama obudalwa ukufiphala kwenyanga.
