Le Orion fu

Orion - ezibalaseleyo phezu emazantsi isibhakabhaka umlaza grand. I-Orion Nebula ithathwa ukuba elivuthayo nebula amadlozi, leyo ngezantsi kuthiwa-"ibhanti" le uhlanjwa umlaza. Kungenxa yale "ibhanti" kulula ukufumana Orion esibhakabhakeni. It iqulathe ezintathu iinkwenkwezi ezimhlophe nemsi Mintaka, uhlukane, Alnitak. Bonke akhiwe kumgca enye, imigama alinganayo emboxo enye kwenye. Le constellation emangalisayo kunye nenyaniso yokuba kukho ezininzi iinkwenkwezi ezinkulu olukhazimlisiweyo. Enye star of Orion ibonakala kancinci umehluko. Xa sikubonisa ngokusebenzisa iteleskopu ngokucacileyo ibonakale iimvakatjhi luzizi. Ibizwa ngokuba "The Great Nebula e Orion", nto leyo ilifu omkhulu hot, igesi olumenyezelayo.

Malunga ubungakanani lelifu irhasi kugwetywa ngenxa yokuba siya kuba 10,000 iinkwenkwezi njengelanga kulo. Le Orion Nebula kubonakala nje kuba ivela Umhlaba kumgama 1340 iminyaka elula. igesi oqaqambileyo esijikeleze iinkwenkwezi ezininzi ashushu abatsha ekupheleni kwe amafu ezinkulu beemolekyuli oluphakathi. Inkqubo lonke namafu nebula, kuquka Horsehead Nebula, 100 amawaka. Iminyaka, iphalale wendalo.

Izazi bakholelwa nakummandla ongqonge umlaza Orion, ukuba zintle kakhulu esibhakabhakeni. Le fu ehlasela lo ezikhanya. ubuso bayo, elisuke phantse ukuba imizuzu 80x60 ye arc, ngaphezu kummandla kwenyanga ngokupheleleyo izihlandlo ezine ngobuhle ngenxa nama-4 ubukhulu inkwenkwezi (ubukhulu sisalathisi ukhanyiso udale into yasezulwini) ugqamile olungileyo, izulu ebusuku. Indawo kwi-ikhweyitha yasezulwini sikuvumela ukuba ubone oko phantse naphi na ehlabathini. Le into indawo na ububanzi bayo yokukhanya-kwiminyaka engama-30. Le yerediyo kunokubonwa ukuba kwinxalenye esemantla uthuli ipasisa zinomtya mnyama ohlukanisa inxalenye kumntla-mpuma we-nebula emzimbeni wayo engundoqo.

I-Orion Nebula lachazwa ekuqaleni ngokweenkcukacha kwi-1656 C. Huygens, nangona ukufunyanwa yayo abanye ngempazamo athethwa sisazinzulu waseJamani I. Tsizatu. Abanye abaxhasi inguqulelo ukuba yavulwa French ngeenkwenkwezi H ku K. Fabri de Peyresk.

Enkosi kwi-Hubble Space Telescope, izazinzulu NASA baye bafumanisa idiski protoplanetary, nto leyo imi kummandla usembindini nebula ebizwa ngokuba "kwikasi". Le ndawo got igama sibonga ayo-4 iinkwenkwezi ezinkulu, apho zicwangciswe enembonakalo trapezoid. Fu i ebumelwaneni esebenzayo kakhulu yeenkwenkwezi abaselula, igesi eshushu kunye nothuli. imithombo enamandla kukona blue embindini kulo iinkwenkwezi 4 kwikasi eliqaqambileyo kakhulu. Loo kukhanya eqaqambileyo unika kubonisa ukukhanya babo esandleni cosmic uthuli nemitha gas insimbi. Dark omdaka fu ifayibha uthuli indawo enkulu. Emazantsi eli nebula na izinto ezininzi substellar - UDema brown.

Le fu abe yinxalenye eliqaqambileyo kakhulu embindini. ebizwa ngokuba yi-amaphiko ayo luphawulwa ngokunciphisa ngokukhawuleza ukukhanya. ukusilela Dark kwenzeka endaweni yokuhlangabezana amaphiko, apho kungenxa yokuba ngobunjalo bayo luphawu ngokuba "intlanzi umlomo". Phambi amaphiko phezu zasebusuku umntu uyakwazi ukubona strip ngqo, leyo ibizwa ngokuba "ikrele." inxalenye Western zokuqhubela ye Orion Nebula ebizwa ngokuba "Sail".

I-Orion Nebula ibekwe ngaphakathi kumnyele wethu kumgama ukusuka Sun 350 pc. Nangona laboratory ezincamathelayo uqinayo le nebula izigidi amaxesha, ubunzima iyonke omkhulu yayo.

Le mfundo isithuba waphawula earthlings kangangamawaka eminyaka. Izazinzulu ezininzi uthini izibakala elibhaqiweyo, qinisekisa babe ngabantu yamaMaya inkwenkwezi le fu eyaziwa kwilizwe lonke ikhalenda yamaMaya.
