Andromeda Nebula - the bolulo tsa lisakramenteng ho

Andromeda Galaxy ke e 'ngoe ea haufi-ufi le lapeng galaxy masihla rona tsa linaleli maholohali. Ke karolo ea seo ho thoeng ke sehlopha ea moo ea lihlopha tsa linaleli, oo litho tsa oona, ho phaella ho seo, ba rona Milky Way le motsoalle galaxy le galaxy tsa Triangle (e leng ka boela ba le satellitari, leha ho le joalo undiscovered). Ha e le hantle, a le haufi haholo le Milky Way ke masihla tse nyenyane - the Large le Small Magellanic Maru. The galaxy ka boeona e kopanyang hoo e ka bang libilione tse linaleli (e leng ka makhetlo a mahlano e kholoanyane ho feta rona), le radius ea lesakaneng lona - fetang 110 tse sekete khanya lilemo. Andromeda galaxy e tsoa ho re neng re ka e leng sebaka sa tse peli le tse limilione tse halofo khanya-lilemo-hang, 'me ho fumana hore o phethahetseng ho fetisisa bakeng sa ho kajeno rometsoe lifofa-sebakeng tla nka lilemo tse limilione tse likete tse 46. Sena ke bonyane ka makhetlo a le lilemo li tseletseng ho feta Earth teng. lipalo tsena li bile li le thata ho nahana!

Histori ea hlokometsoeng tsa galaxy e, moahelani

Teteaneng tsa linaleli ka sepakapakeng ile a bonoa ka Mehla e Bohareng. Ka ho khetheha, e mong oa litaba Arab tsa Andromeda Nebula o bitsoa leru nyenyane. Sena lesihla la linaleli sebakeng sa sehlopha sa linaleli sa Andromeda (eo, ha e le hantle, Nebula a lebitso la eona) o ile a hlokomela ka ho litsebi tsa linaleli li ka lilemo tse makholo. Leha ho le joalo, ha ho na le khatelo-pele ea bohlokoa mabapi le tlhaloso ea eona. Leha ho le joalo, le bokgoni theknoloji ba lumeletse batho ho etsa mohato pele ntlheng ena. Ka 1885, ho na le ketsahalo e thahasellisang - ka galaxy sa Andromeda qhoma ka supernova, le tlhokomelo ea litsebi tsa linaleli li lefatšeng ka bophara ile a retelehela ho tsubuhlellano ena. Leha ho le joalo, ho ea ka phetolelo ea e mong, o ile a phatloha khale, lilemo tse limilione tse 'maloa tse fetileng, empa ha e le hantle hore bo-rasaense ba' nile ba amohela ho tsoaloa ha naleli le lecha - feela leseli le tsoang phatloha, e leng feela hona joale (kapa ho ena, ho 1885) ba tla ho Lefatšeng. Andromeda Nebula, lifoto tsa tsona li neng li pele fumana ka ka 1887, le hlaha ho litsebi tsa linaleli e le e khōlō spiraling lesihla la 'mele. Hlollang le sibolloa entsoeng ka 1921 ke American Vesto Slipher. Bala le tsela ea galaxy, ho e fumane hore Andromeda Nebula ka lebelo haholo rushes ho toba lehlakoreng la Milky Way. Ho latela dipalelo oa kajeno oa litsebi tsa linaleli, lilemong tsa limilione tse likete tse 4 ho tla kopane le lihlopha tsa linaleli tse peli. Sena ha se bonahale eka ke tsa thulana sa lihlopha tse peli tsa linaleli empa ka sebele feta regrouping bohlokoa le ho fetola potoloha bona. Ke kholisehile hore ba bangata ba tla o qobelloang ho tsoa ea 'mele, esita le ho tloha ka hare ho galaxy e sa tsoa thehoa e le sebaka interstellar. Hoa thahasellisa hore ka 1993 e bohareng ea Andromeda Nebula ile ha sibolloa lesihla e 'ngoe ea linaleli. Mohlomong ke mosaletsa oa galaxy ka, Nebula ananelang limilione lilemong tse fetileng.

Features Nebula

Ho ea ka mehopolo ya ka linaleli ea kajeno, ka litsi tsa ho fetisisa lihlopha tsa linaleli spiral jara mekoti supermassive ntsho. Ba thata ho bona ka lebaka la ho qubu e khōlō ea 'mele ea leholimo e bohareng ba ikhara le, hammoho le ka lebaka la ho haelloa ke khanya, kapa pontšo ea leseli. Leha ho le joalo, masoba a ba batsho ka lemoha ka ho sheba hore na ba ama lintho tse ling. Ke labalabela ho tseba hore ka ho ea mantlha ea Andromeda Galaxy ke motswako wa nkgetheng joalo tse peli mekoti supermassive ntsho.
