Umthala esihlala kuwo ubizwa ngokuthi yiMilky Way.  Impela ubuvele ukwazi lokho.  Kepha wazi kangakanani ngalomthala esihlala kuwo?  Kunezigidi zezici, izifiso namakhona ezenza iMilky Way ibe ngumthala okhethekile.  Yikhaya lethu lasezulwini phela, ngoba kulapho iSolar System nawo wonke amaplanethi esiwaziyo atholakala.  Umthala esihlala kuwo ugcwele izinkanyezi, i-supernovae, i-nebulae, amandla, nezinto ezimnyama.  Kodwa-ke, kunezinto eziningi ezisalokhu ziyimfihlakalo kososayensi.  Sizokutshela izinto eziningi nge-Milky Way, kusuka kuzici zayo kuya ekuthandeni nasezimfihlakalweni.  Iphrofayili yeMilky Way Lona ngumthala owenza ikhaya lethu endaweni yonke.  I-morphology yayo ifana kakhulu nokuvuthwa ngezingalo eziyinhloko ze-4 kudiski yayo.  Yakhiwa yizigidigidi zezinkanyezi zazo zonke izinhlobo nosayizi.  Enye yalezo zinkanyezi iLanga.  Kungenxa yeLanga ukuthi sikhona futhi impilo seyakhiwe njengoba sazi.  Isikhungo senkanyezi sisendaweni yeminyaka yokukhanya engama-26.000 ukusuka kwiplanethi yethu.  Akwaziwa ngokuqinisekile ukuthi kungaba nokuningi yini, kepha kuyaziwa ukuthi okungenani umgodi owodwa we-supermassive maphakathi neMilky Way.  Umgodi omnyama uba maphakathi nomthala wethu futhi ubizwe ngeSagittarius A.  Umthala wethu waqala ukwakha cishe eminyakeni eyizigidi eziyi-13.000 edlule futhi uyingxenye yeqembu lemithala engama-50 eyaziwa njengeLocal Group.  Umthala wethu oseduze, obizwa nge-Andromeda, nawo uyingxenye yaleli qembu lemithala emincane ehlanganisa neMagellanic Clouds.  Kusengukuhlukaniswa okwenziwe ngumuntu.  Uhlobo oluthi, uma uhlaziya umongo wendawo yonke nokunwetshwa kwalo, akulutho.  Iqembu Lasekhaya okukhulunywe ngalo ngenhla ngokwalo liyingxenye yomhlangano omkhulu kakhulu wemithala.  Ibizwa ngokuthi i-Virgo supercluster.  Igama lomthala wethu liqanjwe ngebhande lokukhanya esingalibona ngezinkanyezi namafu egesi anwebeka ngaphezu kwesibhakabhaka sethu ngoMhlaba.  Yize uMhlaba ungaphakathi kwe-Milky Way, asikwazi ukuqonda ngokuphelele ngobunjalo bomthala njengoba ezinye izinhlelo zezinkanyezi ezingaphandle zingenza.  Ingxenye enkulu yomthala ifihlwe ungqimba lothuli oluphakathi kwezinkanyezi.  Lolu thuli aluvumeli izibonakude ezibonakalayo ukuba zigxile kahle futhi zithole okukhona.  Singakwazi ukunquma ukwakheka ngokusebenzisa izibonakude ezinamagagasi omsakazo noma nge-infrared.  Kodwa-ke, asikwazi ukwazi ngokuqiniseka okuphelele ukuthi yini esifundeni lapho kutholakala khona uthuli lwe-interstellar.  Singabona kuphela izinhlobo zemisebe ezingena ezintweni ezimnyama.  Izici eziyinhloko Sizohlaziya kancane izici eziyinhloko zeMilky Way.  Into yokuqala esizoyihlaziya ubukhulu.  Ibunjwe njengomoya ovinjelwe futhi inobubanzi beminyaka yokukhanya eyi-100.000-180.000.  Njengoba kushiwo ngaphambili, ibanga eliya maphakathi nomthala lilinganiselwa eminyakeni engama-26.000 yokukhanya.  Leli banga yinto abantu abangasoze bakwazi ukuhamba nayo isikhathi sokuphila nobuchwepheshe esinabo namuhla.  Iminyaka yokwakheka ilinganiselwa eminyakeni eyizigidi eziyizinkulungwane eziyi-13.600, cishe eminyakeni eyizigidi ezingama-400 ngemuva kweBig Bang (isixhumanisi).  Isibalo sezinkanyezi lo mthala onaso kunzima ukubalwa.  Asikwazi ukuhamba ngamunye ngamunye sibala zonke izinkanyezi ezikhona, ngoba akusizi kakhulu ukwazi kahle.  Kunezinkanyezi ezibalelwa ezigidini ezingama-400.000 eMilky Way kuphela.  Okunye okuthandekayo lo mthala onakho ukuthi ucishe ube yicaba.  Abantu abaphikisana ngokuthi uMhlaba uyisicaba bayoziqhenya ngokuthi nalokhu kunjalo.  Futhi ukuthi umthala ungobubanzi beminyaka yokukhanya eyi-100.000 1.000 kepha ubukhulu bokukhanya buyiminyaka eyinkulungwane kuphela.  Kunjengokungathi kuyidiski eyisicaba futhi esontekile lapho amaplanethi efakwe khona ezingalweni zegesi nothuli ezisontekile.  Okuthile okunjalo yisimiso sonozungezilanga, iqembu lamaplanethi nothuli neLanga esikhungweni kwagxilisa iminyaka engama-26.000 yokukhanya ukusuka esikhungweni esishubile somthala.  Ngubani owathola iMilky Way?  Kunzima ukwazi ngokuqinisekile ukuthi ngubani othole iMilky Way.  Kuyaziwa ukuthi uGalileo Galilei (isixhumanisi) wayengowokuqala ukubona ukuthi kukhona iqembu lokukhanya emthaleni wethu njengezinkanyezi ngazinye ngonyaka we-1610.  Lokhu kwaba wuvivinyo lokuqala lwangempela olwaqala lapho isazi sezinkanyezi sikhomba isibonakude saso sokuqala esibhakabhakeni futhi sabona ukuthi umthala wethu wakhiwa izinkanyezi ezingenakubalwa.  Ngasekuqaleni kuka-1920, u-Edwin Hubble (isixhumanisi) nguyena owanikeza ubufakazi obanele bokwazi ukuthi ama-nebulae wokuvunguza esibhakabhakeni empeleni ayemithala yonke.  Leli qiniso lasiza kakhulu ekuqondeni ubunjalo bangempela beMilky Way.  Lokhu kusizile nokuthola usayizi weqiniso nokwazi isilinganiso sendawo yonke esigxile kuyo.  Asinaso isiqiniseko ngokuphelele ukuthi iMilky Way inezinkanyezi ezingaki, kodwa futhi akujabulisi kangako ukwazi.  Ukuzibala kungumsebenzi ongenakwenzeka.  Izazi zezinkanyezi zizama ukuthola indlela engcono yokwenza.  Noma kunjalo, izibonakude zingabona kuphela inkanyezi eyodwa ekhanya kunezinye.  Izinkanyezi eziningi zifihlwe ngemuva kwamafu kagesi nothuli esikhulume ngalo ekuqaleni.  Enye yezindlela abazisebenzisayo ukulinganisa inani lezinkanyezi ukubuka ukuthi izinkanyezi zizungeza ngokushesha kangakanani emthaleni.  Lokhu kukhombisa amandla adonsela phansi nobukhulu.  Ukwehlukanisa ubukhulu bomthala ngosayizi omaphakathi wenkanyezi, sizoba nempendulo.

IMilky Way

Sikutshela konke okwazi kakhulu ngeMilky Way, umthala wethu. Faka lapha ukuze ufunde kabanzi ngomkhathi lapho sihlala khona.

Enye yezingqimba zomoya osivikelayo yi-ionosphere.  Kuyisifunda esiqukethe inani elikhulu lama-athomu nama-molecule akhokhiswa ugesi.  Lezi zinhlayiya ezikhokhisiwe zenziwa ngenxa yemisebe evela emkhathini, ikakhulukazi enkanyezini yethu iLanga.  Le radiation ishaya ama-athomu angathathi hlangothi nama-molecule omoya asemkhathini futhi igcina ngokuwakhokhisa ugesi.  I-ionosphere ibaluleke kakhulu kubantu futhi, ngakho-ke, sizonikezela konke lokhu okuthunyelwe kuyo.  Sizochaza konke odinga ukukwazi mayelana nezici, ukusebenza nokubaluleka kwe-ionosphere.  Izici eziyinhloko Ngenkathi iLanga likhanya ngokuqhubekayo, ngesikhathi sokwenza kwalo likhiqiza inani elikhulu lemisebe kagesi.  Le radiation iwela ezingxenyeni zeplanethi yethu, ishaja ama-athomu nama-molecule ngogesi.  Lapho zonke izinhlayiya sezikhokhisiwe, ungqimba lwakha amafonti esiwabiza ngokuthi yi-ionosphere.  Lolu ungqimba lutholakala phakathi kwe-mesosphere, i-thermosphere ne-exosphere.  Okungaphezulu noma okuncane ungabona ukuthi iqala ebangeni elingamakhilomitha angama-50 ngaphezu kobuso bomhlaba.  Yize iqala kuleli phuzu, lapho iba ephelele ngokuphelele futhi ibaluleke ngaphezu kwe-80 km.  Ezifundeni esisezingxenyeni ezingenhla ze-ionosphere singabona amakhulukhulu amakhilomitha ngaphezu kobuso anweba amashumi ezinkulungwane zamakhilomitha emkhathini yilokho esikubiza ngokuthi i-magnetosphere.  I-magnetosphere ungqimba lomkhathi esiwubiza ngale ndlela ngenxa yokuziphatha kwawo ngenxa yensimu kazibuthe yomhlaba (isibopho) kanye nokusebenza kweLanga okukuyo.  I-ionosphere ne-magnetosphere zihlobene ngamacala ezinhlayiya.  Elinye linamashaji kagesi kanti elinye linamacala kazibuthe.  Izinhlaka ze-ionosphere Njengoba sishilo ngaphambili, yize i-ionosphere iqala ngamakhilomitha angama-50, inezendlalelo ezihlukile ngokuya ngokuhlungwa nokwakheka kwama-ion ayenzayo.  Phambilini, i-ionosphere bekucatshangwa ukuthi yakhiwa izingqimba ezahlukahlukene ezahlukaniswa ezazikhonjwa ngohlamvu D, E, no-F.  Isendlalelo se-F sehlukaniswe izifunda ezimbili ezinemininingwane eminingi okungama-F1 no-F2.  Njengamanje, kunolwazi olwengeziwe lwe-ionosphere ngenxa yokuthuthukiswa kobuchwepheshe futhi kuyaziwa ukuthi lezi zingqimba azihlukile kakhulu.  Kodwa-ke, ukuze ungenzi abantu babe nesiyezi, uhlelo lokuqala ebelinalo ekuqaleni luyagcinwa.  Sizohlaziya ngokwengxenye izingqimba ezahlukahlukene ze-ionosphere ukubona ngokuningiliziwe ukwakheka nokubaluleka kwazo.  Isifunda D Le yingxenye ephansi kunazo zonke ze-ionosphere.  Ifinyelela ebangeni eliphakathi kwamakhilomitha angama-70 nama-90.  Isifunda D sinezici ezihlukile kunezifunda E no-F.  Lokhu kungenxa yokuthi ama-electron ayo amahhala acishe aphele nya ngobusuku obubodwa.  Zivame ukunyamalala njengoba zihlangana nama-oxygen ions ukwakha ama-molecule e-oxygen angathathi hlangothi kagesi.  Isifunda E Lesi yisendlalelo esaziwa nangokuthi iKennekky-Heaviside.  Leli gama linikezwe ukuhlonipha unjiniyela waseMelika u-Arthur E.  Kennelly kanye nesazi sefilosofi saseNgilandi u-Oliver Heaviside.  Lolu ungqimba ludlulela ngaphezulu noma ngaphansi kusuka kuma-90 km, lapho ungqimba D luphelela ku-160 km.  Kunomehluko ocacile nesifunda se-D futhi ukuthi i-ionization ihlala ubusuku bonke.  Kumele kushiwo ukuthi kuncishisiwe impela.  Isifunda F Sinokuphakama okulinganiselwa kusuka ku-160 km kuye ekugcineni.  Kuyingxenye enokuhlushwa okuphezulu kwama-electron wamahhala ngoba kusondele kakhulu elangeni.  Ngakho-ke, ibona imisebe eminingi.  Izinga layo le-ionization alinazo izinguquko eziningi ebusuku, ngoba kukhona ushintsho ekusatshalalisweni kwama-ion.  Phakathi nosuku singabona izingqimba ezimbili: ungqimba oluncane olwaziwa njenge-F1 oluphakeme phezulu, nolunye ungqimba oluphakeme kakhulu olune-ion olwaziwa njenge-F2.  Ebusuku zombili zihlanganisiwe ezingeni lesendlalelo se-F2, esaziwa njenge-Appleton.  Indima nokubaluleka kwe-ionosphere Kwabaningi, ukuba nongqimba lomkhathi ofakwe ugesi kungahle kungasho lutho.  Kodwa-ke, i-ionosphere ibaluleke kakhulu ekuthuthukiseni ubuntu.  Isibonelo, ngenxa yalolu ungqimba singakwazi ukusabalalisa amaza omsakazo ezindaweni ezahlukahlukene emhlabeni.  Singathumela futhi amasiginali phakathi kweziphuphutheki noMhlaba.  Enye yezinto ezibaluleke kakhulu ukuthi kungani i-ionosphere ibalulekile kubantu kungenxa yokuthi isivikela emisebeni eyingozi evela emkhathini.  Ngenxa ye-ionosphere singabona izenzakalo ezinhle zemvelo ezifana ne-Northern Lights (isixhumanisi).  Iphinde ivikele iplanethi yethu ezigcwabeni zamadwala asezulwini angena emkhathini.  I-thermosphere isisiza ukuthi sizivikele futhi silawule izinga lokushisa koMhlaba ngokumunca eminye imisebe ye-UV kanye ne-X-ray ekhishwa yiLanga.  Ngakolunye uhlangothi, i-exosphere iyindlela yokuqala yokuvikela phakathi kweplanethi nemisebe yelanga.  Amazinga okushisa kule ungqimba odingeka kakhulu aphezulu kakhulu.  Kwezinye izindawo singathola i-1.500 degrees Celsius.  Kuleli zinga lokushisa, ngaphandle kokuthi akunakwenzeka ukuthi liphile, kungashisa zonke izinto zomuntu ezidlulayo.  Yilokhu okwenza ingxenye enkulu yama-meteorite ehlasele iplanethi yethu ihlakazeke futhi yakhe izinkanyezi zokudubula.  Futhi kuthi lapho la madwala ahlangana ne-ionosphere nokushisa okuphezulu lapho kutholakala khona kwezinye izindawo, sithola ukuthi into iba yisiqubu futhi izungezwe ngumlilo ize igcine ngokuwohloka.  Ungqimba oludingekayo kakhulu ukuze impilo yomuntu ikhule njengoba sazi namuhla.  Ngalesi sizathu, kubalulekile ukumazi kahle futhi sifunde ngokuziphatha kwakhe, ngoba besingeke siphile ngaphandle kwakhe.
