ILanga ingenye yezinto ezibaluleke kakhulu futhi ezithakazelisayo esimiso sonozungezilanga. Kuthinta cishe zonke izici zokuphila eMhlabeni, kusukela ekunikezeni amandla abalulekile kuya ekondleni imvelo. Nokho, kunezinto eziningi ezithakazelisayo ongase ungazazi ngelanga, kusukela emlandweni walo kuya endleleni elisebenza ngayo namuhla.
Ngakho-ke, kulesi sihloko sizokutshela ezinye ilukuluku ngeLanga okungenzeka ukuthi ubungalazi.
I-Curiosities of the Sun
ubudala belanga
ILanga lavela eminyakeni eyizigidi eziyizinkulungwane ezingu-4.600 edlule ngokunqwabelana kwegesi nothuli oluvela emizimbeni yasezulwini edlule. Abacwaningi kanye nezibalo basikisela ukuthi iseneminyaka engaba yizigidi eziyizinkulungwane eziyisi-5.000 esele, okulingana neminyaka engama-35 nje uma kuqhathaniswa nesikhathi sokuphila koMhlaba. Ngakho-ke, singaphetha ngokuthi iLanga njengamanje lisesigabeni soshintsho somjikelezo walo wokuphila. Ungakwazi ukwandisa umlando wesimiso sonozungezilanga lapha.
Amandla eliwakhiphayo
Ukukhishwa kwamandla eLanga ngomzuzwana owodwa kukholakala ukuthi adlula izidingo zamandla oMhlaba iminyaka engaphezu kwezigidi ezimbili. Lomthombo wamandla wamahhala, ongenamkhawulo uyisihluthulelo sekusasa lethu elisimeme. Ngaphezu kwalokho, ukuqonda ukuthi iLanga liwakhiqiza kanjani la mandla kubalulekile ekuthuthukiseni ubuchwepheshe bamandla elanga obusebenza kahle kakhulu. Thola ukuthi iLanga lisithinta kanjani isimo sezulu soMhlaba.
Izinga lokushisa kwelanga nezingqimba zalo ezihlukene
Ngaphakathi kweLanga kunezingqimba eziningi, ngayinye yazo enezici namazinga okushisa ahlukene. Enhliziyweni yeLanga ungqimba lwalo lwangaphakathi, olwaziwa ngokuthi umnyombo. Ngaphakathi kwenhliziyo, Amazinga okushisa akhuphukela ku-15 million degrees Celsius (ºC) ngendlela emangalisayo., okudala isimo sokweqisa okungenakuqhathaniswa. Kuyathakazelisa ukuthi kungaphakathi kwalesi sifunda lapho ukusabela okuphawulekayo kwezikhali zenuzi kwenzeka, okubangela amandla elanga angenamkhawulo alawula umhlaba wethu.
ILanga lakhiwe izingqimba ezimbalwa, eziqala ngomongo futhi zidlulele endaweni ekhipha imisebe kanye nendawo ehlanganayo. Njengoba sisuka kude nomgogodla, izinga lokushisa liyehla kancane kancane. Ngalé kwalezi zindawo sithola i-photosphere, okuyingxenye yokuqala ebonakalayo yeLanga Olunye ungqimba, olwaziwa ngokuthi i-chromosphere, lwakha ungqimba oluncane olusuka emaphethelweni angaphakathi e-photosphere luye onqenqemeni olungaphandle lweLanga.
Ungqimba lokugcina lweLanga, Eyaziwa ngokuthi i-corona, ihlanganisa indawo engaphandle yeLanga. Njenge-chromosphere, lolu ngqimba lubonakala lapho ukufiphala kwelanga okuphelele kwenzeka. Uma ufuna ukuqonda kangcono izingqimba ezahlukene zelanga, ungase ube nesithakazelo kuzo Ilukuluku mayelana nomkhathi we-Uranus.
Isikhungo samandla adonsela phansi esimiso sonozungezilanga sihlala ilanga.
ILanga, elibekwe njengendawo okugxilwe kuyo, lisebenza njengehange lamandla adonsela phansi kuwo wonke amaplanethi esimisweni sethu sonozungezilanga. Lokhu kuzinza okubalulekile kuqinisekisa ukuthi amaplanethi awazulazuli ngokungenanjongo emkhathini omkhulu womkhathi. Ukuze uqonde ukuguquguquka kwesistimu yethu, bona futhi umsuka wama-asteroids kanye nendima yawo ohlelweni lwelanga.
uhlobo lwenkanyezi
Inkanyezi eyaziwa ngeSol iyingxenye yohlobo lwe-G2V spectral. Ihlukaniswa njengenkanyezi encane ephuzi, ngesisindo esiphakathi kuka-0,8 no-1,2 izikhathi zeLanga (Inkanyezi yohlobo lwe-G2), futhi ikhipha ukukhanya okuqhathaniswa nalokho kwelanga elivamile (inkanyezi yohlobo lwe-V). Ukuhlukaniswa kwayo njengenkanyezi encane ephuzi kuyibeka eqenjini lezinkanyezi eziphila isikhathi eside, okuyenza ikhetheke emzamweni wethu wokuqonda izinkanyezi ezifanayo endaweni yonke. Ukuze uthole imininingwane eyengeziwe, hlola ilukuluku mayelana Mercury kanye nobudlelwano bayo nama-exoplanets.
Ububanzi boMhlaba busithwe yiLanga, elikhulu ngokuphindwe ka-100
ILanga, okuyilona bhizinisi elikhulu kunawo wonke ohlelweni lwethu sonozungezilanga, linobubanzi obungamakhilomitha ayizigidi ezingu-1,4. Ikakhulukazi, ihlanganyela ngokufana noMhlaba ngokuthi wakhiwe ngamakhemikhali. Yakhiwa kakhulukazi i-hydrogen ne-helium. Nokho, ngokungafani noMhlaba, ILanga libhekana nenqubo yomlilo endaweni enkulukazi, elikhiqiza amazinga okushisa akhuphukela ezigidini. Lo mzimba omkhulu wamagesi akhanyayo udlala indima ebalulekile ekukhanyiseni nasekufudumaleni iplanethi yethu, ngaleyo ndlela ukhuthaze izimo ezibalulekile ukuze ukuphila kuchume. Uma ungathanda ukufunda imininingwane eyengeziwe mayelana nezingxenye ze-Sun, hlola ilukuluku of mars.
Ijubane ehamba ngalo
Enye yezinto ezihlaba umxhwele zeLanga ukunyakaza kwalo okungapheli, njengoba limatasa lilandela umkhondo oyisiyingi endaweni emaphakathi yomthala wethu i-Milky Way. Ijubane layo lifinyelela cishe kumakhilomitha angama-220 ngomzuzwana, ukuyivumela ukuthi ihlanganise ibanga elifanayo nokuhlukana koMhlaba neLanga ngezinsuku eziyi-7 kuphela. Ngokomongo, lokhu kusho ikhono elimangalisayo leLanga lokunqamula amabanga amade ngesikhathi esifushane uma kuqhathaniswa. Ngaphezu kwalokho, ukukhanya kwelanga kuthatha cishe imizuzu engu-8 ukufika emhlabeni wethu, okusivumela ukuba siqonde ukuthi kuthatha isikhathi esingakanani imisebe ukuhamba kulo mthala omkhulu. Ingabe ufuna ukwazi amaqiniso athakazelisayo mayelana nobusika?
Amandla adonsela phansi aphindwe izikhathi ezingama-28 kunawomhlaba
Ngesisindo salo esikhulukazi esakhiwe ngokuyinhloko i-hydrogen ne-helium, iLanga linamandla adonsela phansi adlula kude lawo oMhlaba. La mandla aqiniswa ukuminyana okuphawulekayo kweLanga, okuyinto Ijiya ngokuphindwe ka-1,4 kunamanzi. Ngenxa yalokho, ubukhulu beLanga bufinyezwa endaweni encane kakhulu uma kuqhathaniswa neplanethi yethu. Amandla adonsela phansi elanga abalulekile ukuze kugcinwe ukuzinza kwesimiso sonozungezilanga kanye nomzila wamaplanethi. Ukuze uqonde kangcono lesi sici, hlola.
Akunakwenzeka ukuhlala phezu kweLanga
Izinga lokushisa lobuso beLanga, elifinyelela emazingeni adlulele, lakha isithiyo esikhulu esivimbela noma yimuphi umzamo wokuhlala kulo. Lokhu kushisa okunamandla kungaba yingozi kuzo zombili izinto nakubantu abazama ukuxhumana nendawo yayo.
Naphezu kokubonakala kwayo kwendilinga evuthayo, Izinga lokushisa langempela leLanga licishe libe ngu-5.500ºC. Lokhu kushisa okumangalisayo kuwumphumela wokuhlangana kwezikhali zenuzi okwenzeka ngaphakathi kwawo, lapho amazinga okushisa enyuka aze afike ezigidini zama-degree. Ngokumangalisayo, ingaphakathi leLanga lishisa ngisho nangaphezu kwendawo yalo ebonakalayo, okuchaza ukukhanya kwalo okukhazimulayo nokukhipha imisebe. Uma ufuna ukuqonda inqubo ye-nuclear fusion kangcono kakhulu, sincoma I-curiosities yoMfula iNayile kanye nobudlelwano bayo nezinqubo zemvelo.
Ikusasa lisekuhloleni amandla elanga
Naphezu kokubona kwethu ilanga isikhathi eside, luseluningi ulwazi esingaluthola ngalendikimba yasezulwini ekhanyisa futhi isekele ukuphila kwethu. Ngaphakathi kokujula kwayo okungaqondakali kulele izimfihlo ezingenakubalwa ezinamandla okulolonga ikusasa lethu. Ukuhlola ilanga nokuqonda amandla alo kanye nokukhishwa kwemisebe kunamandla okuvula amathuba amasha okuthuthukisa ubuchwepheshe belanga obubili obusebenzayo nobuzinzile. Ukuqhubeka ujula elangeni nokufunda ngezigigaba zalo ezihlukene kubalulekile ukuze siqhubekele ekusetshenzisweni ngempumelelo kwalo mthombo wamandla ovuselelekayo nongenamkhawulo.
