Andromeda - Umthala esiseduzane i-Milky Way. Collision ye-Milky Way futhi Andromeda

Andromeda - Umthala, eyaziwa nangokuthi i-M31 kanye NGC224. Lokhu kumiswa Helical sise ibanga mayelana 780 kp (izigidi ezingu-2,5 light-years) ukusuka eMhlabeni.

Andromeda - Umthala esiseduzane i-Milky Way. Mina wawuqamba yokudumisa inkosazana wasenganekwaneni. Uphawula 2006 kwaholela esiphethweni sokuthi zikhona cishe izinkanyezi isigidintathu - okungenani izikhathi ezimbili kunaleyo i-Milky Way, bakuphi, kunezinguqulo ezingaba ngu-200 -. 400 bhiliyoni Ososayensi bakholelwa ukuthi leli ukushayisana ye-Milky Way kanye Andromeda Galaxy kuzokwenzeka mayelana 3, iminyaka engu-75 bhiliyoni ubudala, futhi ekugcineni uzobe kwakhiwa giant umthala okweqanda noma isiyingi. Kodwa kamuva lesi. Okokuqala funda, "Princess wasenganekwaneni" libukeka.

Isibalo ikhombisa Andromeda. Umthala has a imivimbo okwesibhakabhaka nomhlophe. Bakha sazungeza futhi ukufukamela ashisayo akhazimula inkanyezi enkulu. Dark imivimbo oluhlaza-grey bheka umahluko phakathi ngokucijile ngokumelene isizinda izindandatho elikhanyayo futhi ubonise ezindaweni lapho obukhulu ifu imifece inkanyezi kumiswa isiqala nje. Lapho sigcina e ingxenye ebonakalayo nomkhakha we inhlasi Andromeda ingaphezu efana Kuvunguza izingalo. Esikhathini uhla ultraviolet lezi zokwakheka zifane indandatho izakhiwo. Bakhandwa ngaphambilini sitholwe NASA isibonakude. Izazi zezinkanyezi zazo zikholelwa ukuthi lezi izindandatho ziwubufakazi kumiswa imithala e ukungqubuzana engumakhelwane iminyaka kwezigidi ezingu-200 edlule.

Kumasathalayithi ka-Andromeda

Kanye-Milky Way, Andromeda enezinto eziningi iziphuphutheki yemifino, 14 babo kakade wathola. Adume kakhulu - M32 kanye M110. Yiqiniso, akunakwenzeka ukuba izinkanyezi Umthala ngamunye nqwamana nomunye, njengoba ibanga likhulu kakhulu phakathi kwabo. Iqiniso ukuthi kuzokwenzeka okufanayo ngokoqobo, ososayensi zisekhona umqondo ngempela ezingacacile. Kodwa kakade igama yasungulwa ngenxa usana esizayo. Mlekomeda - ngakho lokho okwamanje ozalwa giant Umthala ososayensi.

izibhelu izinkanyezi

Andromeda - Umthala, ababebalelwa 1 isigidintathu izinkanyezi (10 ^12), futhi i-Milky Way - 1 bhiliyoni (3 x 10 ^11). Nokho-ke, ukungqubuzana ithuba mayelana nezinto zasemkhathini azinakwa, njengoba kukhona ibanga elikhulu eliphakathi kwabo. Ngokwesibonelo, inkanyezi eseduze weLanga Proxima akhiwe kude zeminyaka 4.2 ukukhanya (4 x 10 ¹³ km), noma 30 million (3 x 10 ⁷⁾ Sun diameters. Cabanga ukuthi inkanyezi yethu - akuphonse ukudlala ithenisi lasetafuleni. Khona-ke, Proxima Centauri izobukeka a ipea, elise at ibanga 1,100 km away, futhi i-Milky Way ukunweba phandle ezingu 30 amakhilomitha. Ngisho nezinkanyezi ezisendaweni enkabeni yalo mthala (futhi lokhu lapho emakamu kunabo bonke kubo) zitholakala ngezikhawu 160 billion (1.6 × 10 ¹¹⁾ km. Kufana ibhola for table tennis kuwo wonke 3,2. Ngakho-ke, ithuba lokuthi yimuphi izinkanyezi ezimbili nqwamana lapho ukuhlanganisa imithala, incane kakhulu.

Collision ka Izimbobo Black

Andromeda futhi i-Milky Way babe emaphakathi supermassive izimbobo black signSagittarius A (3.6 * 10 ⁶ wt Sun) kanye into ngaphakathi cluster P2 Galactic-nucleus. Lezi izimbobo black nibuthana ngesinye isikhathi eduze maphakathi imithala elalisanda kumiswa, wedlula amandla esemkhathini izinkanyezi, okuyinto ngokuhamba kwesikhathi ngeke bayeke trajectory ngaphezulu. Inqubo ngenhla kungathatha izigidi zeminyaka. Lapho izimbobo omnyama ngeke asondele ibanga unyaka owodwa ukukhanya okuvela each nye they ihlaba umkhosi amagagasi okudonsa izinto. amandla Orbital iyoba namandla nakakhulu, kuze kube ekubumbaneni usuphothuliwe ngokugcwele. Ngokusekelwe idatha sekulingisa, olwenziwa ngo-2006, i-Earth kungenziwa ekuqaleni kulahliwe cishe kwaze kwaba enkabeni yalo mthala elalisanda kumiswa ke kuzothatha cishe omunye izimbobo omnyama futhi wagudluza ngale Mlekomedy.

isiqinisekiso theory

Umthala i-Andromeda kuyeza kithi ngesivinini mayelana 110 amakhilomitha ngomzuzwana. Kuze kube 2012 yayingekho indlela ukwazi yini noma cha ukungqubuzana kuzokwenzeka. Baphethe ngokuthi kuyinto cishe akunakugwenywa, ososayensi wasiza-Hubble Space Telescope. Ngemva ethungatha Andromeda ukunyakaza kusuka 2002 kuya ku-2010, kwaphethwa ngokuthi ushayisile kuzokwenzeka eminyakeni engaba yizigidi eziyizinkulungwane 4.

imihlola Okufanayo zisabalele endaweni yonke. Ngokwesibonelo, kukholelwa ukuthi Andromeda zokugcina baxhumene okungenani oyedwa Umthala. Eminye imithala yemifino ezifana SagDEG, futhi manje uqhubeka ukuhlangabezana ne-Milky Way, ukudala yomkhakha owodwa.

Ucwaningo luphinde abonisa ukuthi i-M33, le Triangulum Galaxy, noma, - ngobukhulu kanye omele brilliant iningi Iqembu Local - futhi ngeke iqhaza kulo mcimbi. Kungenzeka-ke Siyoba yini isiphetho engena emzileni kwakhiwa emva kokuhlangana into, futhi esikhathini eside esizako - ubunye oyinhloko. Nokho, i-M33 ukungqubuzana Milky Way phambi eduze Andromeda noma isimiso sethu sonozungezilanga bayophonswa ngaphesheya Iqembu Endaweni, ayifakiwe.

Isiphetho Solar System

Ososayensi base-Harvard baphikisa ngokuthi imigomo inhlangano zemithala incike ijubane tangential we-Andromeda. Ngokusekelwe izibalo, saphetha ngokuthi kukhona 50% wokuthi ngezinye confluence sonozungezilanga bayophonswa ibanga kathathu njengengcebo enkulu kunemicebo samanje isikhungo i-Milky Way. Vele awazi ukuthi baziphathe kanjani ku-Andromeda Galaxy. Earth, futhi, ingaphansi usongo. Ososayensi bathi 12% amathuba esinayo ngemva kwesikhathi esithile ukushayisana uyowiswa emuva ngale "ekhaya" yethu yangaphambili. Kodwa lesi senzakalo engeke idonse liveze imiphumela ezinzima onqabayo komthala wethu, futhi izindikimba zasezulwini ngeke ubhujiswe.

Uma Sizibeka eceleni lonjiniylea kwamaplanethi ke esikhathini ukushayisana zemithala is elikhazimulayo kobuso bomhlaba kakhulu futhi ngeke ahlale namanzi, futhi ngenxa yalokho.

Imiphumela engemihle

Lapho lemiklamo amabili ehlangana, le-hydrogen ekhona amadiski zabo onomfutho. Iqala kumiswa kakhulu izinkanyezi ezintsha. Isibonelo, kungabonakala nasemkhakheni i Umthala uxhumana NGC 4039, eyaziwa nangokuthi "antenna". Esimeni abayi-Andromeda futhi i-Milky Way Kunenkolelo yokuthi igesi embhidlangweni wabo ukuhlala encane. Inkanyezi ngeke okukhulu, nakuba kungenzeka kwavela Quasar.

uhlangane yi

Galaxy kwakheka at kwalapho, abacwaningi ngaphambilini okukhulunywe Mlekomeda. Umphumela sekulingisa ubonisa ukuthi into okuholela kuyoba i ukuma okweqanda. isikhungo sayo kuzodingeka kwabantu engezansi Izinkanyezi kuka imithala zanamuhla okweqanda. Kodwa cishe futhi ukuma isiyingi. Kuzoya kakhulu ngokuthi ingakanani igesi uhlala ngaphakathi kuyi-Milky Way futhi Andromeda. Esikhathini esizayo esiseduze imithala esele okuvela kuyo le Group Local kuzohlanganisa ku yomkhakha owodwa, futhi ngeke ukuqala isigaba esisha kwemvelo.

Amaqiniso mayelana Andromeda

• Andromeda - emthaleni ngobukhulu kuleli Qembu Local. Kodwa kungenzeka akulona okukhulu kakhulu. Ososayensi bathi ukuthi i-Milky Way uye wagxila kakhulu esimnyama, futhi yilokho okwenza yomthala wethu omkhulu ngokwengeziwe.
• Ososayensi ukuhlola Andromeda ukuze baqonde umsuka kanye kwemvelo lezi zokwakheka ke, ngoba eseduze Kuvunguza Umthala kithi.
• Andromeda kusukela uMhlaba ubukeka emangalisayo. Abaningi ngisho ukuphatha ifotho ke.
• Andromeda has a obukhulu kakhulu Galactic-nucleus. izinkanyezi ezinkulukazi Akukhona nje zitholakala phakathi nendawo, kodwa futhi okungenani oyedwa supermassive kwesikhala sezinhlamvu kufihlwe core.
• Izingalo zayo Kuvunguza okokusonteka ngenxa ukuxhumana okudonsa phakathi imithala angomakhelwane: M32 kanye M110.
• Ngaphakathi Andromeda iphathwa okungenani 450 globular inkanyezi amaqoqo. Phakathi kwabo - omunye obukhulu kakhulu, bayakwazi ukuthola.
• I-Andromeda Galaxy - into ezikude kakhulu ukuthi kungabonwa ngeso lenyama. Uzodinga ezinhle uyibuka iphuzu futhi ukukhanya ubuncane.

Ekuphetheni, sikucebisa abafundi ngokuvamile amehlo abo esibhakabhakeni esigcwele izinkanyezi. Igcina eningi entsha futhi engaziwa. Thola isikhathi sokuba bagcine yonke ngempelasonto. Umthala i-Andromeda esibhakabhakeni - umbono okufanele nakanjani ukubona.
