Magiraksi ari pedyo neMilky Way ndeeLocal Group. Anoonekwa zviri nyore nescope ine mavanga. Kutaura zvazviri, mamwe, akadai seAndromeda neMagellanic Clouds, anogona kutoonekwa nemaziso chaiwo.
Saizvozvowo, mapoka enyeredzi akati wandei anotenderera pedyo neMilky Way . Semuenzaniso, Sagittarius Dwarf Elliptical Galaxy yakawanikwa muna 1.994 iri kure ne70.000 light-years, uye Canis Major Galaxy muna 2.003 iri kure ne25.000 light-years. Aya ndiwo mapoka enyeredzi maviri ari pedyo akawanikwa kusvika pari zvino.
Makwara enzou ari pedyo nemukaka
Nezvezviri pamusoro, tinogona kutaura pazasi kuti ndeapi mapoka enyeredzi ari pedyo neGwara Renzou
andromeda galaxy
Garazi reAndromeda , iro rinozivikanwawo seSpiral Galaxy M31, Messier 31, kana NGC 224, iboka renyeredzi rine dhayamita ye220 light-years (kana tichitarisa galaxie halo) uye 150 light-years pakati pemagumo emaoko aro anotenderera. Rine nyeredzi dzakati wandei dzakafanana neboka redu renyeredzi.
Ndiyo zvakare chinhu chiri kure zvikuru chinoonekwa nemaziso asina chinhu kubva kuPasi (kunyange vamwe vachiti vanokwanisa kusiyanisa Triangulum Galaxy, iri kure zvishoma). Iri kure nemakiromita 2,5 miriyoni echiedza kuenda kuAndromeda. Pamwe chete neboka redu renyeredzi, ndiro guru uye rakajeka kupfuura mamwe ese ari muLocal Group, rine magirafu madiki angangoita makumi matatu pamwe nemagirafu matatu makuru anotenderera: Andromeda, Milky Way yedu , uye Triangulum Galaxy.
Data inoenderana neAndromeda Galaxy
Chimwe chezvinhu zvinonakidza nezve Andromeda Galaxy ndechekuti iri kure nemamiriyoni maviri nehafu emakore echiedza kubva kuPasi, uye kunyangwe ichionekwa nemaziso, saizi yayo yakaoma kufungidzira nekuti kupenya kwayo kwakaderera. Mufananidzo uri pamusoro unotibatsira kufungidzira kuti taizoisiyanisa sei muchadenga dai yakanga yakajeka zvakakwana kuti ionekwe zviri nyore. Iri kure, asi inotyisa.
Chinhu chinonyanya kukosha paAndromeda Galaxy ndechekuti inosvika kune yedu, Milky Way, nekumhanya kwemakiromita mazana matatu pasekondi. Zvinofungidzirwa kuti mukati memakore mabhiriyoni matatu kusvika mashanu, mapoka maviri enyeredzi anogona kuroverana. Kunyange zvazvo nyeredzi nemitumbi yekudenga iri muboka rega rega renyeredzi isingazoroverane, kutenderera kwadzo pamwe nekurongeka kwehurongwa hwadzo kwaizokanganiswa.
Kufungidzira kuri pazasi kunoratidza kuti taizoona sei Andromeda Galaxy painoswedera pedyo neyedu. Hatizovepo kuti tiione kana kuirondedzera, saka zvakakodzera kufungidzira.
Magellanic Clouds
Imwe nyeredzi iri pedyo neMilky Way iMagellanic Clouds, magirafu maviri madiki ari muLocal Group. Yakakura inozivikanwa seLarge Magellanic Cloud, uye diki seSmall Magellanic Cloud. Kunyangwe zvagara zvichifungidzirwa kuti zvinotenderera Milky Way , zvakaonekwa munguva pfupi yapfuura zvinoratidza zvakasiyana.
Panyaya iyi, mapoka aya enyeredzi anoonekwa kubva kuSouthern Hemisphere pausiku hwakajeka, husina mwedzi. Anoonekwa semakanda maviri machena madiki, akatarisana nenzvimbo yeCrux kubva pamaonero enzvimbo yekuchamhembe kwedenga.
Hunhu hweMagellanic Clouds
Chimwe chezvinhu zvatinogona kuona mune rimwe remagalaxy ari pedyo neMilky Way ndechekuti Magellanic Clouds ane chimiro chakaoma kunzwisisa. Ruzivo rwunoratidza kuti magalaxy ese ari maviri akakanganiswa zvakanyanya nemasimba emvura panguva yekudyidzana kwawo neMilky Way. Zvasara zvehydrogen isina kusimba zvinozvibatanidza pamwe chete uye negalaxy yedu, iyo yakakanganiswawo nemakore ese ari maviri , sezvo akakanganisa zvikamu zvekunze zvedhisiki rekudenga.
Panguva imwe chete, kupararira kwavo kwakasiyana uye hushoma hwavo zvinovasiyanisa neMilky Way muzvinhu zviviri zvakakosha. Chekutanga, vane hutsi hwakawanda hwemvura uye havana simbi yakawanda kupfuura Milky Way. Chechipiri, vose vanozivikanwa nekuda kwemaburi avo uye nharaunda dzavo diki dzenyeredzi. Maburi ari mumagalaxi aya anopa chitarisiko chinoshamisa.
Nekune rimwe divi, nekuda kwekukasira kwadzo kwechiedza, mapoka enyeredzi ose ari maviri anoita seari munhano yawo yekutanga pamwe chete neGwara renzou; Chokwadi, zvave zvichinzi Magellanic Clouds angave akatanga mukudhumhana pakati peAndromeda galaxy nerimwe gwara renzou, ari marara kubva pachiitiko ichi uye akakandwa akananga kunzira yemukaka.
Triangulum Galaxy
Garazi reTriangulum diki kana tichienzanisa nedzakavakidzana nadzo dzakakura, dzinoti Milky Way neAndromeda Galaxy (rine mapuraneti ari pakati pemabhiriyoni makumi matatu nemakumi mana kusvika mabhiriyoni makumi mana kana tichienzanisa nemabhiriyoni mazana maviri nemakumi mana eMilky Way pamwe nematriliyoni eAndromeda Galaxy), asi saizi yaro yakafanana neyemamwe magirakisi emuchadenga ari muchadenga.
Saizvozvowo, Triangulum Galaxy inhengo yeLocal Group yemagalaxy - yechitatu pakupenya nehukuru - uye inoita kunge yakabatana neAndromeda, iri kure nemakore echiedza 720000 uye inotenderera munzvimbo isingawanzoonekwi zvakanyanya.4 LGS 3, imwe yezvikamu zvidiki zveLocal Group, ingangove galaxy yakabatana nayo.
Usual Inquiry nezve Triangulum Galaxy
Chimwe chezvinhu zvakakosha zvakawanikwa nezvemagalaksi ari pedyo neMilky Way ndechekuti Triangulum Galaxy yakaongororwa naGiovanni Battista Odierna asati asvika 1654, uyo akaibatanidza neboka rakavhurika ratinoziva iye zvino seNGC 752. Charles Messier akaizivisa zvakajeka muna 1764, achiitsanangura seM33 musi wa25 Nyamavhuvhu. Triangulum Galaxy yakazivikanwawo naWilliam Herschel musi wa11 Gunyana, 1784, uyo akaipa nhamba yeatomu H V.17. M33 ndeimwe ye "spiral nebulae" yekutanga yakazivikanwa naLord Rosse.
Herschel akasarudzawo nzvimbo yakakura kwazvo yeH II yeiyi galaxy (nebula ye fuzzy manifestation inobata ionized hydrogen) seH III.150, achiiparadzanisa negalaxy ndokuitumidza kuti NGC 604. Mupfungwa iyi, iyi galaxy, sezvakaonekwa kubva kuPasi, NGC 604, yakaganhurirwa kuchamhembe kwakadziva kumabvazuva kwepakati pegalactic , uye ndeimwe yenzvimbo huru kwazvo dzeH II dzinoonekwa, ine dhayamita ye1500 light-years uye maonero akafanana neaya eM42.
Zvisinei, kunyange zvazvo dzisingakwanise kunzi dzakaenzana neNGC 604, dzimwe nzvimbo dzeHII muTriangulum dzakanaka uye dzinopenya zvakaenzana, dzine zita radzo reNGC. Mienzaniso yakajeka yeizvi inosanganisira NGC 588, NGC 592, uye NGC 595.
Saizvozvowo, Triangulum Galaxy inogona kuonekwa neziso risina kusimba mumamiriro ezvinhu asina kujairika, uye kune vanhu vazhinji, ndicho chinhu chiri kure kwazvo chinoonekwa neziso risina kusimba. Zvisinei, yakakura kwazvo uye yakaoma kuona, uye chishandiso chakanakisa chekuiona imabhainokura maviri , ayo anogona kutoratidza maoko ayo akatenderera mumamiriro ezvinhu akanaka kwazvo.
Chekupedzisira, chinhu chakakosha uye chinokwezva chakasimbiswa nenyanzvi nezvemapoka enyeredzi ari pedyo neMilky Way, kunyanya M33, ndechekuti ine nyeredzi itsva dzakawanda, uko zuva rinobuda nekukurumidza kwatakajaira Milky Way yedu , zvakare ichibata mamwe emapoka emuchadenga akapfuma uye ane chiedza chakanyanya eLocal Group kubva kuNGC 604.
