Yintoni Galaxy, yaye yintoni na ke?

Abo ungathanda ukujonga isibhakabhaka ebusuku, mhlawumbi waphawula ebanzi band ezahlukeneyo kwimicu fefa (eqaqambileyo, sasinda perceptible, oluhlaza, omhlophe, njl) iinkwenkwezi. Le klasta yeyona Way.

Yintoni a Way? Enye eemfihlelo inkulu iphela kuxhomekeke kwinto yokuba iinkwenkwezi ezininzi azizaliswanga saa ngokungakhethiyo kwisithuba, kwaye neyohlulwe iminyele. Xa kakhulu indlela abantu efanayo kuhlala umzi, ukushiya isithuba phakathi zokuhlala engenanto.

Iplanethi yethu yinxalenye kumnyele iMilky Way. Amanye amagama iminyele baziwa kakuhle; i ezinkulu amaNcinane Magellanic Amafu, i Andromeda Galaxy. Them siyakwazi ukubona ngeliso lenyama, ngoxa abanye ukude kakhulu Earth. ayiphumelelanga kakhulu ixesha elide ukubona ngayo kwezinye iinkwenkwezi, kwafumaniseka ukuba enze kuphela kwinkulungwane yama-20.

"Yintoni Way?" - lo mbuzo uye oosonzululwazi abanomdla elide. Kodwa ke impumelelo yokwenene kule ndawo kwenzeke kwinkulungwane yamashumi amabini emva kwexesha, xa wadalwa kwaye waqalisa iteleskopu isithuba "Hubble".

Ubungakanani kumnyele wethu likhulu kangangokuba akunakwenzeka ukuba ukucinga. One lamawaka anamakhulu Umhlaba iminyaka kuya kufuneka umqadi ukukhanya ukufikelela naye kwelinye icala ukuya kwelinye. Xa iziko yalo ibekwe ngumongo apho amasebe eziliqela imigca anda ezele iinkwenkwezi. "Density" oku kubonakala kuphela, eneneni afumaneka kakhulu ezinqabileyo.

Kukho iindidi ezahlukeneyo beminyele. Bona ezahluke ngokumila, ubunzima, ubungakanani, kwakunye izinto eziqulathwe. Bonke ziqulathe irhasi kunye inkwenkwezi uthuli. Kukho kwezinto, okweqanda, mgaqweni, isigaba-efana kunye nezinye iintlobo beminyele.

Yintoni a Way? Yintoni na ubudala babo? Njani ziyasebenza? Zeziphi iinkqubo ezikhoyo? iminyaka yabo malunga ulingana ubudala iphela. Kuba izazinzulu kusenjalo mfihlelo, yintoni na ingundoqo kumnyele. Kuye kwafunyaniswa ukuba eminye nuclei kakhulu esebenzayo. Yaba isimanga, ngokuba kwada ezifunyenweyo, kwakucingwa ukuba nucleus a oxineneyo amakhulu ezigidi zeenkwenkwezi. Imitha (optical nerediyo) zisenokwahluka kwezinye umphakathi galactic kwiinyanga ezimbalwa. Oku kuthetha ukuba ndinikhululele isixa elikhulu wamandla (okungakumbi ngendlela flash supernova) ngexeshana elifutshane.

Ngowe-1963, ityhileke kukho izinto ezintsha ngokupheleleyo ukuba abe imbonakalo inkwenkwezi-ezimile Babizwa ngokuba quasars. likhanya labo, njengoko kanti, iminyele iqaqambile kude kunathi. Kuyamangalisa ukuba nokukhanya quasars zinokwahluka.

Formation leminyele - yinkqubo ngokwendalo nasekusungulweni iphela, aphuma phantsi kwempembelelo amandla omxhuzulane. Le iindidi kunye neemilo iminyele kungenxa ezahlukeneyo iimeko yabo yokuzalwa. Ucinezelo lo mnyele unokuthatha 3 billion. Iminyaka. Ngeli xesha, i-gas inguqu kwinkqubo inkwenkwezi. Le yi ucinezelo lelifu gas akha neenkwenkwezi (kwi ezixineneyo ethile obushushu elaneleyo iinkqubo fusion).

Ngokuthe ngcembe oovimba igesi oluphakathi sele kuphele, kwaye ukuyilwa iinkwenkwezi iba ayayo. Xa usebenzise zonke izibonelelo, Galaxy ezijikeleze uguqulwe lenticular, eliquka nocatshulo iinkwenkwezi ezibomvu. Eli nqanaba imithala okweqanda izibonelelo zabo igesi ndayichitha omnye Iminyaka 15-20 billion. Eyadlulayo.

Abantu abaninzi sinengcamango yokuba yintoni Umnyele ukusekwa movies fiction yezenzululwazi eliqela, amaqhawe abathanda ukuba bahambe babeziindleko kwendawo, tyelela izijikelezi-langa engaziwayo ziwe. Enyanisweni, oku na zisacwangciselwe ixesha elizayo sijonge kuyo. Nokuba sisiya ngesantya sokukhanya (ongayi kuba lide kakhulu), ngoko ukuba i Andromeda Galaxy (kumnyele wethu elikufutshane) sifumana iminyaka kuphela emva nezigidi ezi-2.5. Nangona (ngokutsho izibalo ngeenkwenkwezi) siyasondela nathi kwiminyaka 4-5 billion, senze wethu iMilky Way, nto leyo eya kukhokelela ukuyilwa Galaxy entsha okweqanda.
