Isayensi yezinkanyezi kanye nesayensi ehlobene, Zibe yizinsika eziyisisekelo zokutholwa okuhlukahlukene. Enye yeziningi iye yakwazi ukubona ngokunembile ukuma kwemithala kanye, ikakhulukazi, i-Milky Way. Ngaphakathi kokuhambisana kwayo, kunendawo ethile ebaluleke kakhulu eyaziwa ngokuthi ingalo ye-Orion. Kodwa iyini ngempela le ndawo?
Kancane kancane izimfihlakalo zendawo yonke ziye zadalulwa, ziletha ulwazi olwengeziwe lwesintu. Nakuba lesi sakhiwo singesona esisha uma kuqhathaniswa, siye sasiza ukuqonda, ngokucace kakhulu, ukusebenza komthala. Ngokulandelayo, yindawo ethile lapho iSolar System yenza ukuphila futhi, ngakho-ke, yilapho futhi uMhlaba ulele khona.
Ungase futhi ube nentshisekelo esihlokweni sethu: Ingabe izinto ezimnyama ziyisici esigcwele kakhulu endaweni yonke?
Ukubaluleka kwengalo ye-Orion kuyiqiniso okumele laziwe ngokucaciswa okukhulu
Isifundo somkhathi nazo zonke izimfihlakalo ezihlobene nawo, kancane kancane ibilokhu iqoqa izithelo zayo. Ngokuhamba kwesikhathi, izambulo ezintsha bezibalulekile ukuze kuzuzwe ukukhula okukhulu kobuhlakani.
Isibonelo esicacile salokhu wucwaningo lwemithala nokuhambisana kwayo ngokujwayelekile. Ngokuqondile, i-Milky Way, lapho kuhlala khona i-Solar System, iyona nto eyinhloko yocwaningo kanjalo.

Ngokuhamba kwesikhathi, izindawo ezakhayo sezitholakele, ebizwa ngokuthi izingalo ezithile. Enye yeziningi ingalo ethandwayo ye-Orion, eqanjwe kanjalo ngenxa yokusondelana kwayo nomlaza we-Orion.
Ukubaluleka kwayo kulele ekutheni iyindawo noma indawo yeSolar System, ngakho-ke, iplanethi enguMhlaba. Ngokusekelwe kulokhu, ukungena emininingwaneni ecacile mayelana nokubunjwa kwayo, ukunyakaza, phakathi kwabanye, kuzosiza ukudalula okwengeziwe mayelana nesikhala.
Kuze kube manje, ngale kwezindlu iSolar System, futhi iyikhaya lezinto ezinkulu zasemkhathini. I-Orion Arm iyikhaya le-Orion Nebula enkulu, kanye nezinye izindikimba zasezulwini ezivelele.
Phakathi kwabaningi, kukhona iqoqo leCygnus X, Polaris nokunye. Njengokungathi lokho akwanele, le ndawo ye-Milky Way iyaqhubeka ikhula, yingakho isafihla ezinye izimfihlakalo. Akungabazeki ukuthi ingenye yezindawo ezicebisa kakhulu ezakha umthala lapho ukuphila kulele khona.
I-Milky Way kanye nengalo ye-Orion. Sinjani isimo samanje sakho kokubili?
Ucwaningo lwemithala likuqinisekisile lokho Lezi zinezimo ezihlukene kuye ngokwakheka kwazo. Ngalowo mqondo, kukhona lawo ane-spiral conformation njengoba kunjalo nge-Milky Way.
Ngaphezu kwalokhu kutholakala, ingxenye ngayinye ye-Milky Way noma i-spiral esebenzayo, yaziwa ngokuthi ingalo. Ngakho-ke, iMilky Way kanye nengalo ye-Orion ziyingxenye yesimiso esifanayo, enye iyingxenye yolunye.
Ingalo ye-Orion ingenye nje kwezingu-9 okwenza i-Milky Way imise ukuzungeza kwayo. Ngayinye yalezi zingalo noma izandiso ezivunguzayo zinezici zazo, amagama kanye nezinto ezihlanganisiwe.
Kokubili i-Milky Way kanye nengalo ye-Orion ziyizinto ezimbili ze-cosmic ezinokubaluleka okungaphezu kokubaluleka kwendawo yonke. I-Milky Way ibhekele ukwakhiwa kweSolar System, kuyilapho ingalo ye-Orion kuyindawo yayo ngqo.
Okwamanje, Kukhona ukuvumelana okuhlukahlukene mayelana nengalo ye-Orion. Abanye ososayensi balondoloza ukuthi kuwukuncika engalweni eyodwa ebaluleke kakhulu, ingalo eyaziwa kakhulu yePerseus.
Ngakolunye uhlangothi, enye ingxenye yomphakathi wesayensi ithola ukuthi ingalo enesandiso esanele sokuzimela. Iqiniso lendaba ukuthi, ku-Milky Way, ingenye yezingxenye ezibaluleke kakhulu enazo kuqoqo lwayo.
Eqinisweni, Ngaphambili kwakucatshangwa ukuthi iyisixhumanisi kwezinye izindawo zomhlaba. Ngenxa yalokho, yabizwa ngaleso sikhathi ngokuthi i-Orion Spur ngaleyo njongo evamile.
I-Orion Arm ye-Milky Way nakho konke okwaziwayo ngayo. Ithini yonke imininingwane?
Ngaphambili, inkolelo-mbono yayiwukuthi uMhlaba wawuyinkaba yendawo yonke, i-Solar System, konke okwaziwayo. Nokho, ngenxa yesayensi yezinkanyezi yesimanje, kuyaziwa ukuthi kunendawo yonke engenakuqondwa.
Ngokusekelwe kulolu phenyo, kwakungenzeka ukuhlonza ingalo ye-Orion ye-Milky Way. Ngenxa yokubonakala njalo komthala, kwaba nokwenzeka ukuqinisekisa zonke izingxenye eziwakhayo.
Njengoba ingumthala ovunguzayo, ngamunye wabo umele insika noma ingalo enomumo ofanayo. Sekukonke, eziyisi-9 zazo zinikeza ukuphila esimweni esithile se-Milky Way nakho konke okushiwo ukuhambisana kwayo.

Mayelana nengalo ye-Orion ye-Milky Way, iphakathi kwengalo yeSagittarius nengalo kaPerseus. Kusukela yabonwa, le ndawo yomthala ithathwa njengencike engalweni yePerseus. Nokho, ngokuhamba kwesikhathi, iphinde ifakwe ohlwini njengebhizinisi elizimele.
Noma kunjalo, ingalo ye-Orion ayinawo amaphiko afanayo nalawo ayeqanjwe ngaphambili. Ngempela, ingenye yezingalo ezithandelayo ezincane kunazo zonke, kodwa ifanelekile ngokuba indawo eqondile yeSolar System.
Lena yindlela eyaziwa ngayo indawo yeSolar System
Ngokusebenzisa izibonakude eziyinkimbinkimbi kakhulu zazo zonke izinhlobo, kube nokwenzeka ukuba kutholwe kahle indawo yeSolar System. Ngaphezu kwalokho, usebenzisa indlela ye-interferometers, dweba udonga noma umdwebo we IMilky Way, kube lula.
Ngenxa yalokhu, isifunda esiphakathi kwezinkanyezi engalweni ye-Orion eyaziwa ngokuthi i-Bubble yasendaweni isihlonziwe. Lokhu kwakheka okuminyene kwe-hydrogen nezinye izinto kube yikhaya le-Solar System. Okwamanje, i-Solar System ihambe ngokwanele ukuthi ingabonwa emaphethelweni angaphakathi ebhamuza lendawo.
