I esigaxeni Orion

Orion - evelele phezu sesihlasela ingxenye eseningizimu ye isibhakabhaka umlaza grand. I-Orion Nebula kubhekwa ukuba elikhazimulayo ekushayweni esigaxeni, okuyinto ngezansi okuthiwa "Leli bhande" we umlaza. Kungenxa yalesi "Leli bhande" Kulula ukuthola Orion esibhakabhakeni. Siqukethe ezintathu izinkanyezi okumhlophe nokuluhlaza Mintaka, nza, Alnitak. Zonke zitholakala emgqeni efanayo nangesikhathi alinganayo amabanga emincane komunye nomunye. Lokhu Umlaza ezimangalisayo kanye neqiniso lokuthi kukhona eningi egqamile giant izinkanyezi. Omunye inkanyezi Orion kubonakala kancane anyakaza. Lapho sikubonisa ngokusebenzisa isibonakude kuyabonakala ukufiphala hazy. Ibizwa ngokuthi "I-Great Nebula e Orion", okuyinto ifu omkhulu ashisayo, igesi akhazimula.

Mayelana kungenziwa yahlulelwe usayizi ifu igesi kusukela lokuthi kusukela kwalo bezingeke zibe 10,000 izinkanyezi bunjengelanga. Lokhu i-Orion Nebula kancane sengathi nje ngoba kusukela Earth at ibanga 1340 iminyaka ukukhanya. Glowing igesi ozungezayo ashisayo izinkanyezi abasha abambalwa ngesikhathi engcupheni amafu giant yamangqamuzana interstellar. Lonke uhlelo lwamafu we esigaxeni, kuhlanganise Horsehead Nebula, ngoba izinkulungwane 100. Iminyaka, zize zihlakazeke e yonke enkulukazi.

Izazi zezinkanyezi bakholwe ezizungeze umlaza Orion, enhle kakhulu esibhakabhakeni. Lokhu esigaxeni ehlasela umzimba yiyona bhá. Indawo yayo, ezisabalele cishe imizuzu efika ku-80x60 ka arc, okukhulu kuna endaweni egcwele kane futhi Ukukhalipha ngenxa cishe 4 izinkanyezi ezidlula (ezidlula kuyinto inkomba kungakhanyi ukukhanya wadala into yasezulwini) has ukubonakala ezinhle esibhakabhakeni ebusuku. Indawo senkabazwe yasezulwini ikuvumela ukuba ubone ukuthi cishe nomaphi emhlabeni. Lokhu into isikhala ungaphakathi ubukhulu bayo yokukhanya-iminyaka engaba ngu-30. I isibonakude kuyabonakala ukuthi engxenyeni esenyakatho othulini sihamba isiqeshana mnyama ehlukanisa engxenyeni esenyakatho ye-mpumalanga yesifundazwe esigaxeni emzimbeni wayo oyinhloko.

I-Orion Nebula yaqale wachaza ngokuningiliziwe ngo-1656, Huygens, nakuba ukutholakala yayo abanye bengase benze iphutha ashiwo usosayensi German I. Tsizatu. Ezinye nabasekeli version ukuthi wavulwa French sezinkanyezi H ukuba K. Fabri de Peyresk.

Ngenxa ye-Hubble Space Telescope, ososayensi be-NASA batholé disk protoplanetary, okuyinto Itholakala imaphakathi esigaxeni wabiza "Trapezium". Le ndawo lethiwa sibonga izinkanyezi 4 omkhulu, okuyinto ahlelwe umumo trapezoid. Nebula kuyinto endaweni asebenzayo kakhulu izinkanyezi abasha, igesi ashisayo nothuli. imithombo Inamandla lokhukhanya blue maphakathi ke kukhona 4 elikhanyayo kakhulu Trapezium izinkanyezi. ukukhazimula okunjalo elikhanyayo unika kukhombisa ukukhanya abo ngothuli cosmic futhi kwemisebe igesi ionized. Obunsundu fibre uthuli esigaxeni indawo enkulu. Ezansi le esigaxeni kuyinto izinto eziningana substellar - dwarfs ensundu.

Lokhu esigaxeni linengxenye elikhanyayo kakhulu isikhungo. kwamaphiko aso okuthiwa zinezikhathi lincibilika ngokushesha ukugqama. ukwehluleka Dark kwenzeka endaweni tekuhlangani wamaphiko, okuyinto ngenxa nesifanekiso salo isici okuthiwa "inhlanzi umlomo". Ngaphambi amaphiko ku zasebusuku umuntu angabona strip iqonde, okuthiwa "Sword." Western ingxenye ukucasha we-Orion Nebula ngokuthi "Span".

I-Orion Nebula itholakala ngaphakathi komthala wethu buqamama eLangeni 350 pc. Nakuba laboratory cleaner baqaphe lokhu esigaxeni izigidi izikhathi, isisindo ingqikithi omkhulu walo.

Le mfundo isikhala waphawula Earthlings izinkulungwane zeminyaka. Ososayensi abaningi bathi mayelana amaqiniso itholiwe, eqinisekisa ukuthi abantu Mayan inkanyezi yalesi esigaxeni wayaziwa emhlabeni wonke ikhalenda lamaMaya.
