Yintoni igama kumnyele wethu? Anatomy of siba olukhulu

Namhlanje ukuba igama kumnyele wethu, nawuphi na umfundi owaziyo. Kodwa ke akusoloko. Milky Way - umbuso omkhulu, eliquka amakhulu ezigidi lweenkqubo kubotshwa ngumxhuzulane obalaseleyo - na kwilizwe lethu yesiqalo. Uye usoloko kwatsala ingqalelo uluntu yambangela umdla olukhulu. Phantse zonke izizwana bamandulo kunye namazwe khona impendulo yayo kumbuzo kwegama kumnyele wethu.

Kwamanye amazwe ehlabathini yamandulo ebizwa iMilky Way ooThixo abathandekayo, kwabanye - Star Bridge. Umzekelo, isebenzisa isibizo "River waseZulwini" e-China yamandulo. Umanyano kulo mbandela yayingekabikho. Kodwa noko kunjalo, kuzo zonke iimbombo ihlabathi lamandulo iMilky Way yayigqalwa engcwele. Imbeko wakhe, wakha iitempile, waqubuda.

Uphononongo lwenzululwazi imbali iMilky Way ubuncinane amawaka amabini eminyaka. Kwaye ngoku lee abalazi igama kumnyele wethu, ngenxa yokuba lo mbuzo sibi yobomi wayiqala ibe yintoni emlindeleyo nathi kwixesha elizayo, ezi alohlukaniswa ingqiqo. Kuphela inxalenye kwangoku wendalo iphela, kukho malunga neebhiliyoni amabini, anamanci iminyele.

Ngamnye kubo ekhethekileyo kubume bayo, likhulu ngobukhulu kwaye usoloko ihamba. Galaxy ndlongondlongo. Ziye ke wazalwa ngenxa nezibangelwa ezukileyo cosmic kwaye kufa ukufa ngobundlobongela. Galaxy - inkwenkwezi ezalwa ngokwenene. Stars, silinike ubomi indalo yethu, sibakhanyisela, othe bakhe, wazalelwa Sisihloko galactic omkhulu yerhasi nothuli, le yokwakha zonke imizimba yasezulwini.

Enye yezi zakhiwo emangalisayo kukuba isithuba giant nendlu yethu intle - iMilky Way. Uninzi kwimbali ubunye boluntu ku umbuzo ngendlela kuthiwa kumnyele wethu lwenzululwazi, kwakungelula. Ngaphezu koko, ngokuba ixesha elide, izazinzulu bakholwa iMilky Way kumnyele kuphela kwindalo iphela, kukho uhlobo kwisiqithi lokuchuma kulwandle olukhulu cosmic yaye zingasaphili.

Kodwa ke ngo-1924, Erwin Hubble ukugcina nesibhakabhaka esimnyama kunye ngoncedo ngezibonakude ezininzi obuphambili ixesha, watshintsha ingcamango jikelele. Waphawula ngokunzulu emajukujukwini iiklabhu ezichanileyo ukukhanya wagqiba ukuba uyifumene akukho izinto abangatshatanga kunye lonke conglomerates inkwenkwezi ngaphandle iMilky Way. Ngenxa yoko, Hubble iye yaguqula ngeenkwenkwezi wazisa kwinqanaba elitsha yokufunda ukwakha ikhaya esembindini.

The Milky Way omelwe ukwenziwa nokwenyuka, uhlobo luqhelekileyo ezisebenzisanayo nkwenkwezi. Ubume kumnyele wethu neemfihlelo enkulu iphela ngoku ifikeleleke ngakumbi emehlweni abantu, ngenxa ngeeteleskopu mihla nesithuba yaqonda, ezosulela rhoqo Earth iinkcukacha eziqokelelweyo.

Ngoko ke, siye safumanisa ukuba ukwabiwa iinkwenkwezi umntu uphawu uphawu eqondeka kakuhle, nto leyo kukuba ingqalelo njengoko besondela kweso esembindini kwandisa kakhulu. Oku kwakusenza izazinzulu ukuba wenze isigqibo malunga ubukho kumbindi umzimba omkhulukazi kunye womxhuzulane enamandla kakhulu.

Iziko of kumnyele wethu, ibekwe lekroza Sagittarius, kubonakala ngathi, lixakekile inkohlakalo emngxunyeni omnyama. Kunjalo, le ingcaciso kuphela esengqiqweni kukuba inzululwazi yanamhlanje kunganika ukusasazwa leenkwenkwezi. Kwixesha elizayo, kumnyele wethu ulindele ukuba ibe yintlekele enamandla yesiqalo - le zicinywe i Andromeda Galaxy, ekufuneka thina ngokukhawuleza ngokukhawuleza. Ngenxa yale ntlekele Andromeda, ubukhulu mkhulu kakhulu iMilky Way, ukufunxa inkwenkwezi yethu wahlala, nto leyo iya kuyeka ukusebenza, kodwa endaweni kwasekwa galaxy elitsha. Kwaye ke Ukudaleka wendalo yonke uya kuqhubeka ...
