Andromeda - Way wapafupi kwa Milky Way. Kugunda wa Milky Way ndi Andromeda

Andromeda - Way, amatchedwanso M31 ndi NGC224. Izi mapangidwe helical ili pa mtunda wa pafupi 780 kp (miliyoni 2,5 kuwala zaka) ku Earth.

Andromeda - Way wapafupi kwa Milky Way. Ine dzina polemekeza kalonga lanthano. Kuzipenya mu 2006 zinachititsa kuti anazindikira kuti pali za nyenyezi thililiyoni - nthawi osachepera awiri kuposa mu Milky Way, komwe iwo ali, pali 200 -. Biliyoni 400 Asayansi akukhulupirira kuti kugunda wa Milky Way ndi Andromeda Way zidzachitika za 3, zaka mabiliyoni 75, ndipo potsiriza chimphona elliptical kapena zozungulira Way adzakhala anapanga. Koma pambuyo pa izi. Choyamba kuphunzira, "lanthano Mfumukazi" zikuwonekera.

chithunzi limasonyeza Andromeda. The Way ali buluu ndi zoyera mikwingwirima. Iwo ndi mphete padziko ndi kusunga otentha losonyeza chimphona nyenyezi. Mdima buluu imvi mikwingwirima tisiyanitse zikuchepa ndi maziko mphete yowala ndi kusonyeza kumadera wandiweyani mtambo cocoons wa nyenyezi mapangidwe wayamba chabe. Pamene kuona mu mbali yapadziko lapansi ya sipekitiramu wa mphete wa Andromeda ndi zambiri zofanana mwauzimu manja. Mu uthunthu ultraviolet formations awa amafanana mphete nyumba. Iwo anali kale anapeza mwa NASA zakutali. Akatswiri a sayansi ya amakhulupirira kuti mphete awa ali umboni wa mapangidwe nyenyezi mu kugunda ndi oyandikana zaka zoposa 200 miliyoni zapitazo.

The makina a Andromeda

Komanso Milky Way, Andromeda angapo a nthambi nyenyezi yaing'ono, 14 kale poyera. Wotchuka - M32 ndi M110. Kumene, ndi chodziwikiratu kuti nyenyezi iliyonse Way adzawombana ndi mzake, monga mtunda ndi wamkulu kwambiri pakati pawo. chakuti chomwecho chidzachitika mu zenizeni, asayansi ndi yosokoneza kwambiri lingaliro. Koma kale anatulukira dzina wakhanda m'tsogolo. Mlekomeda - kotero kuti ali asanabadwe chimphona Way asayansi.

kusiyana nyenyezi

Andromeda - Way zilipo zankhaninkhani, 1 nyenyezi (10 ^12), ndi Milky Way - 1 biliyoni (3 x 10 ^11). Komabe, mwayi kugunda zinthu zakuthambo ndi negligible, popeza pali mtunda wamkulu pakati pawo. Mwachitsanzo, nyenyezi pafupi ndi Sun Proxima ili pa mtunda wa zaka 4.2 kuwala (4 * 10 ¹³ km), kapena 30 miliyoni (3 x 10 ⁷⁾ Sun diameters. Tiyerekeze kuti nyenyezi athu - mpira kwa kusewera tebulo tenesi. Ndiye, Proxima Centauri lidzaonekera mtola ndi, inali pa mtunda wa makilomita 1,100 kwina, ndi Milky Way kuwonjezera makilomita outwards mpaka 30 miliyoni. Ngakhale nyenyezi pakati pa Way (ndipo apa ndi pamene ndende wamkulu) zili pa intervals biliyoni 160 (1.6 × 10 ¹¹⁾ Km. Ziri ngati mpira tebulo tennis uliwonse 3.2 Km. Choncho, mwayi kuti nyenyezi ziwiri adzawombana pamene merging nyenyezi, ndi yaing'ono kwambiri.

Kugunda kwa Black mabowo

Andromeda ndi Milky Way ndi chapakati supermassive mabowo wakuda signSagittarius A (3.6 * ¹⁰ June dzuwa misa) ndi chinthu mkati m'bulu P2 Galactic phata. mabowo izi wakuda atasonkhana ina pafupi pakati pa nyenyezi utangoyamba kudutsa mphamvu yozungulira nyenyezi, umene nthawi kuloza ku njira yodutsamo apamwamba. The ndondomeko pamwamba zingatenge zaka mamiliyoni ambiri. Pamene mabowo wakuda azifika pafupi ndi mtunda wa chaka chimodzi kuwala kwa wina ndi mnzake, iwo zimatulutsa mafunde yokoka. mphamvu yozungulira adzakhala amphamvu kwambiri, mpaka pophatikizana ndi mofikapo. Yachokera pa kafukufuku kayeseleledwe Imachitika mu 2006 Dziko Lapansi akhoza poyamba anataya pafupifupi likulu la Way utangoyamba, ndiye kudzatenga za munthu mabowo wakuda ndi kutsitsidwa kupitirira Mlekomedy.

chiphunzitso chitsimikiziro

The Andromeda likuyandikira ife pa liwiro pafupifupi 110 makilomita pa mphindi. Mpaka 2012 panalibe njira kudziwa kapena kuwombana zidzachitika. Pomaliza kuti pafupifupi mosalephera, asayansi anathandiza Hubble Space Telescope. Pambuyo kutsatira Andromeda kayendedwe kuchokera 2002 mpaka 2010, izo anapeza kuti kugunda zidzachitika biliyoni 4 zaka.

zochitika zofanana ndi ambiri chilengedwe cha. Mwachitsanzo, akukhulupirira kuti Andromeda otsiriza alumikizirana ndi Way chimodzi. Magulu ena nyenyezi yaing'ono monga SagDEG, ndipo tsopano kupitiriza kukumana ndi Milky Way, kupanga gulu limodzi.

Kafukufuku amasonyeza kuti M33, ndi Triangulum Way, kapena, - wachitatu yaikulu ndi nthumwi wanzeru kwambiri wa Gulu Local - nawonso nawo mwambo umenewu. Ambiri mwina chidzaonekera yolowera kanjira anapanga pambuyo pophatikizana wa chinthu, ndi m'tsogolo - kugwirizana mtheradi. Komabe, M33 kugunda ndi Milky Way pamaso pafupi Andromeda kapena ubongo wathu dzuwa adzaponyedwa kupitirira Gulu Local, mulibe.

Tsogolo la System Dzuwa

Asayansi a ku Harvard amati mawu a gulu la nyenyezi zimadalira liwiro tangential wa Andromeda. Kuchokera pa anapezazo, ife anazindikira kuti pali mwayi 50% kuti pa confluence a dongosolo la zowalitsa adzaponyedwa ku mtunda katatu kuposa panopa pakati Milky Way. Sindikudziwa basi momwe zinthu mu Andromeda Way. Lapansi, nawonso, ndi kuopsezedwa. Akatswiri a sayansi amanena 12% n'kutheka kuti tili patapita nthawi kugunda adzakhala anakankhira mmbuyo kutsidya wakale "kunyumba" wathu. Koma mwambo umenewu si ayenera kubala aakulu mavuto pa dongosolo dzuwa, ndi matupi akumwamba silidzaonongedwa.

Ngati ife amapatula zomangamanga mapulaneti, ndiye nthawi ya kugunda kwa nyenyezi ndi losonyeza padziko lapansi kwambiri ndipo sadzapulumuka madzi madzi, chotero moyo.

chingachitike mbali

Pamene mizere yozungulira awiri amaphatikizidwa, mphatso haidrojeni pa mbale wawo wothinikizidwa. Umayamba tima mapangidwe nyenyezi yatsopano. Mwachitsanzo, zingaoneke mu zimavuta Way NGC 4039, mwinamwake lotchedwa "tinyanga". Mu chochitika cha pophatikizana wa Andromeda ndi Milky Way amakhulupirira kuti mafuta galimoto zawo kukhala laling'ono. nyenyezi sudzakhala ngati kwambiri, ngakhale zikuoneka zikamera wa quasar a.

kuphatikiza chifukwa

Way anapanga pa mphambano ya, ofufuza kale amatchedwa Mlekomeda. The chifukwa kayeseleledwe limasonyeza kuti chinthu chifukwa adzakhala ndi mawonekedwe elliptical. likulu lake adzakhala osalimba m'munsi mwa nyenyezi kuposa nyenyezi ano elliptical. Koma mwina mawonekedwe zozungulira. Zikudalira mmene mpweya amakhalabe mu Milky Way ndi Andromeda. Posacedwapa kuyang'anira dzikoli otsalira a Gulu Local adzakhala kuphatikiza mu gulu limodzi, ndipo chidzakhala chiyambi cha watsopano siteji chisinthiko.

Zowona zenizeni zokhudza Andromeda

• Andromeda - ndi Way waukulu mu Gulu Local. Koma mwina si kwambiri chachikulu. Asayansi kuti Milky Way lolunjika kwambiri nkhani mdima, ndi amene amachititsa Way yathu yaikulu kwambiri.
• Asayansi kufufuza Andromeda pofuna kumvetsa chiyambi ndi zamoyo wa formations zimenezi, chifukwa yapafupi mwauzimu Way kwa ife.
• Andromeda ku Earth amayang'ana chidwi. Ambiri amatha Chithunzi izo.
• Andromeda ali ndi wandiweyani kwambiri galactic phata. Osati nyenyezi lingamutsatire zili pakati, komanso mmodzi supermassive wakuda dzenje zobisika pakati.
• manja ake mwauzimu ndi wokhotakhota chifukwa cha mogwirizana yokoka pakati pa nyenyezi oyandikana: M32 ndi M110.
• Mkati Andromeda ankachitira osachepera 450 globular nyenyezi masango. Pakati pawo - mmodzi wa wandiweyani kwambiri, amatha kudziwa.
• Andromeda Way - akutali kwambiri zinthu Tingaone ndi apoyera. Muyenera wabwino mumtengomo ndipo glare osachepera.

Pomaliza, ife amalangiza owerenga zambiri anakweza maso awo kuti nyenyezi. Kumalimbikitsa kwambiri chatsopano ndi losadziwika. Pezani nthawi yopuma kusunga chilengedwe pa mlungu. Andromeda mu mlengalenga - akuona kuti muyenera ndithudi kuwona.
