Ichi chinyorwa chinoratidza zvese zvaunoda kuziva nezve gore remagellanic, ramba uchiverenga kuti uzive zvinonyanya kukosha zveiri nyeredzi inoshamisa. Pazasi isu tinokuratidza maitiro ayo akatanhamara, cosmic chimiro, morphology uye zvimwe zvakawanda.
Chii chinonzi Magellanic cloud?
Gore reMagellan, kana kuti rinozivikanwawo seMagellanic nebula, igwara renzou rine chimiro chakasiyana, izvi zvinoreva kuti inonzi darf galaxy, kusiyana nemamwe mapoka enyeredzi ari munzvimbo yechadenga, idiki zvakanyanya. kupfuura kunyange edu, nokuda kwechikonzero ichi inotsanangurwa senyeredzi duku.
Historia
John Herschel, anozivikanwa nekuve munhu wekutanga munhoroondo yegore reMagellan, akanyatsocherechedza gwara renzou iri riri 163.000 light years away, uyezve, richionekwa nekuve pachinzvimbo chetatu chemapoka enyeredzi anoswedera kunzira yemukaka. .
Gore rakati riri munharaunda uye padyo neMilky Way, raisazivikanwa makare-kare sezvo rakanga risingaonekwe zvachose nguva isati yasvika kana maonero. Chokwadi chakachengeta kusazivikanwa, asi kuvepo kwayo kunozoburitswa nekufamba kwemakore uye kuitwa kwehunyanzvi hutsva.
Kubva kumaodzanyemba kweArabia, gore rakatanga kuonekwa. Kuti gare gare kuita zvidzidzo pamusoro pechitarisiko chayo, maitiro uye morphology, kutaurwa kunoitwa nezvekuvapo kwayo mugwaro rakanyorwa nenyanzvi yenyeredzi inonzi Abd Al-Rahman Al Sifien. Ndiani akaita rekodhi yekutanga-yepamusoro-soro rekodhi achitaura nezvayo mumagwaro ake.
Kune rumwe rutivi, mukondinendi yeEurope, Fernando de Magallanes ndiye akazvipa humbozha hwekuicherechedza mukati mekuita rwendo rwakanga rwakaita senzira yakakosha, yakananga kunharaunda yepasi. Kuburikidza naiyo akakwanisa kuona uye kuona kekutanga mukuru gore remagellanic. Kuti igozopihwa zita remhando yepamutemo, asi panguva ino, inonziwo diki nebula.
Imwe nguva mushure mekunge gwara renzou rapihwa zita, rinodaidzwa nekunyorwa seGore reMagellan mukuremekedza munhu wekutanga akafumura nekutsanangura kuvepo kwegwara rakasiyana siyana. The Milky Way, kufanana nemakwara enzou ese, ine chimiro chakakura, kana tikaswedera kugwenga rakaita seGwara renzou kubva kure kure, chinhu chekutanga chatichasangana nacho chichava makwara enzou emuguta, zvinhu zvakaita segore reMagellan, saka isu kuswedera pedyo negwara renzou, tichawana kupararira kwakatsetseka kwemasumbu enyeredzi.
Imwe neimwe ine zviuru zana kusvika kumiriyoni imwe neimwe nyeredzi. Sezvingatarisirwa nehurongwa hwega hwega, mamwe magalaxi haana kutenderera kana elliptical, asi akasiyana, kusanganisira makwara enyeredzi senge Magellanic gore.
Gore reMagellan raive nhau pasi rose, nekuda kwekuputika kwe supernova yainzi 1987A iyo yakaputika muna Kukadzi 1987 mugore reMagellan iro rakadzidzwa zvakadzama nevanoongorora nyeredzi kuti vafunge nezvemafambiro enyeredzi, vachiongorora mabatiro angangoita nemhedzisiro. izvo zvanga zvichizovandudza nguva ye epicenter.
La gore remagellanic Rainzi igwara renzou rakanga riri pedyo zvikuru neGwara Renzou, idi iro rakazodzidzwa zvakadzama, kusvika pakuwanwa muna 1994 kwegwara renzou rakaenzana rakaenzana rine mavara edenderedzwa, iro rakanzi Sagittarius galaxy. Kwakazotevera gore ra2003 nyeredzi itsva yakawanikwa ine zita rekuti Can Mayor.
Naizvozvo, iyo gore remagellanic akaiswa pachinzvimbo chechitatu mundandanda yemapoka enyeredzi ari pedyo zvikuru neGwara Renzou, tichifunga kuti raionekwa serinokurumidza zvikuru maererano nenzvimbo yaro, kune iro rinozonzi nhasi rimwe remapoka enyeredzi anozivikanwa, pamwe chete neboka renyeredzi. Andromeda galaxy, uye Sagittarius elliptical.
Hunhu hweMagellan Cloud
Chinhu chikuru che gore remagellanic, inorara muchimiro chayo chakakwana chinotsanangurwa segwara renyeredzi diki, izvo zvinoreva kuti iri, semamwe akawanda, rinopwanya mold, sezvo risina elliptical kana spiral-shaped maitiro. Maumbirwo aro anoreva kuti vesainzi vakariisa murondedzero yemapoka enyeredzi ane chimiro chisina kujairika.
Zvinofanira kucherechedzwa kuti haasi mapoka enyeredzi ose ari muchadenga ane zvimiro zvakaita seelliptical. Kunyange zvazvo mapoka enyeredzi mazhinji ane dhizaini yakatenderedza, mamwe anowanzonzi madiki ane zvimiro zvinokurumidza kuaratidza semakwara enzou asina kujairika.
Sezvatakambotaura, elliptical galaxy yeSagittarius yakazoonekwa imwe nguva gare gare, chokwadi chakaita kuti masayendisiti aongorore nzvimbo yairi munzvimbo yekunze kwainogara. Migumisiro yacho yaishamisa, ichiwana kuti izvi pamwe chete ne gore remagellanic Iwo akabatana uye ane hukama kune mumwe nemumwe.
Pachinhambwe chingangoita 75 zviuru zvemakore chiedza, iyo Sagittarius galaxy uye iyo gore remagellanic vari kure uku. Kukanganiswa kunoitika kuburikidza nesimba rinoitwa nemafungu kuburikidza nekudyidzana neGwara renzou kunokonzera kukanganisa kunokanganisa zvimwe zvinokonzeresa kuti mapoka ese enyeredzi abatane kuburikidza nemamwe mafungu.
Mafungu aya anoumbwa neneutral hydrogen, izvo zvinoita kuti mapoka ese enyeredzi aite kudyidzana kunowanzo konzera mamwe mamiriro anoguma akuvadza zvekunze izvo zvinoenderana negalactic disk yavo.
Both the gore remagellanic, segwara renzou reSaturn, vane morphological maitiro anoita kuti ave akasiyana uye anoshamisa zvakanyanya, maererano nehukuru, uye chimiro chaainacho, zvinoratidzwa kuti pamberi pezvikamu zviviri izvi zvehuremu, uye chimiro, pane zvinhu zviviri zvinozvisiyanisa. kubva kumitambo Milky Way.
ari Hunhu hwemakwara enzou Sezvo izvi zvine mazinga akakwirira egasi, chigadzirwa chinovasiyanisa kubva kune galaxy yedu, uyezve, sechinhu chekujekesa, havana pfuma yesimbi. Chimwe chinhu chekusimbisa ndechekuti ivo vanogadzirwa nebulae, pamwe chete nekuve nekubatanidzwa kwenyeredzi diki.
ari Sayenzi maficha bvumira kuti kuburikidza nekuongorora nyeredzi, kuongorora kunotora nzira itsva, iyo inoratidza kuti gore reMagellan maererano nenyanzvi rinogona kunge rakatanga kuburikidza nekudhumhana kana kuvhuvhuta, iyo yakasunungura boka renyeredzi reAndromeda, (muvakidzani wedu wepedyo) uye rimwe boka renyeredzi, izvo zvakakonzera kupfurwa kwemarara. uye zvimedu, izvo gare gare zvakaguma muboka redu renyeredzi.
Pakupedzisira, kuwanwa kweiri boka renyeredzi rinoshamisa kunomirira nzanga yesainzi kufambira mberi kukuru maererano nezivo nemipiro iyo sainzi kuburikidza nekuongorora nyeredzi yakapa kumunhu nekuda kwetsvakiridzo yenguva dzose yaanoramba achigadzira.
Kunyange zvazvo tave tichiziva nezvokuvapo kwemapoka enyeredzi kweinopfuura hafu yezana remakore, tichiri kukwanisa kutsanangura kuti nei ariko. Zvisinei, kuvapo kwaro muchadenga kunosiya zvakawanda zvokutaura, uye zvinhu zvomuchadenga zvisingagumi zvokudzidza.
Hwaro hwezivo yavanhu nguva dzose huchaenda mberi zvikuru, uye kunyange kutozosvikira panguva ino yomuzuva razvino uno, mamwe masayendisiti akaita mipiro mikuru iyo yakanga iri youkoshi hukurusa kutsinhirana namashoko akave ari pamusoro pechimiro chechisiko chapose pose, kunyange zvakadaro, ihwo hwaro hunokosha zvikuru. hazvina kukwana.. Pane zviuru zvezvinhu izvo zvidzidzo zvemuchadenga zvisati zvave kukwanisa kuona.
