The great Magellanic Cloud iboka renzou riri pedyo raifungidzirwa kuva boka renyeredzi risingaenzaniswi kusvikira vazivi venyeredzi vanyatsoritarisa. Inogona kunge iri spiral. The Large Magellanic Cloud negwara renyeredzi raro, Magellanic Cloud, rinongo onekwa mumatenga ekumaodzanyemba kweNyika. Iyo Milky Way inogara ichidya gasi rinoyerera kubva kuMagellanic Clouds kuburikidza neMagellan Flow. Pakupedzisira aya mapoka enyeredzi madiki maviri anogona kubonderana neGwara Renzou.
Muchikamu chino tichakuudza zvese zvaunoda kuziva nezveLarge Magellanic Cloud, maitiro ayo, mavambo uye zvimwe zvakawanda.
Mhando huru
Mamiriro makuru eMagellan Cloud ndeaya anotevera:
- Inogona kuonekwa kubva kumaodzanyemba kwehemisphere uye ndiro yechipiri padyo negalaxy kune Magellanic Cloud.
- Ndiyo imwe yemakwara enzou gumi nerimwe ari kutenderera paMilky Way yedu uye Inoonekwa segwara renzou risingaenzaniswi.
- Inosanganisira matombo matsvuku, nyeredzi, makore madiki enyeredzi, uye nzvimbo inopenya yemaitiro anooneka anozivikanwa seTarantula Nebula.
- Iyo inopenya yemazuva ano supernova, SN1987A, yakaputika muMagellan Cloud.
- Iine wedzero inosvika 30.000 light years.
- Inofungidzirwa kuti ndiyo yakakura kwazvo setiraiti yenzou yeMilky Way.
- Iyo yakatanhamara red knot pazasi inozivikanwa seTarantula Nebula, inzvimbo inogadzira nyeredzi muLarge Magellanic Cloud.
- Ndeyerudzi rwakavhiringwa rod-spiral.
- Iyo ine dhayamita ye14.000 metres uye chinhambwe che163.000.
- Ine nyeredzi dzinenge mabhiriyoni makumi matatu.
Chinhu chikuru cheMagellanic Cloud chimiro chayo chese, chinotsanangurwa segirazi diki, zvinoreva kuti rinopwanya mold semamwe magalaxi mazhinji nekuti harina elliptical kana spiral features. Chimiro chayo chakaita kuti masayendisiti aiise mumitsara yemakwara enzou ane zvimiro zvisina kujairika.
Zvinofanira kucherechedzwa kuti haasati ari mapoka enyeredzi ose ari muchadenga ane chimiro chakakwana, chakadai se<em>ellipse. Nepo mapoka enyeredzi mazhinji aine maitiro ezvinotenderera, mamwe mapoka enyeredzi, anowanzonzi makwara enzou maduku, anowanzoita. ane zvimiro zvakati izvo zvinokurumidza kuarondedzera semakwara enzou asina kujairika.
Kuwanikwa kweMagellan Cloud
Idi rekuti Sagittarius elliptical galaxy rakazowanikwa imwe nguva gare gare zvakaita kuti masayendisiti aongorore kuti rinogara kupi muchadenga. Mhedzisiro yacho yaishamisa, kuona kuti iyi neMagellan Clouds yakabatana uye yakabatana.
Pachinhambwe chemakore angangoita 75.000 XNUMX chiedza chemakore. iyo Sagittarius galaxy uye Magellanic Cloud ari kure kure. Kukanganiswa kunoitwa nemasimba anoitwa nemafungu kuburikidza nekudyidzana kwawo neGwara renzou kunokonzera kukanganisa kunokanganisa zvimwe zvinokonzeresa izvo zvinoita kuti mapoka enyeredzi maviri abatane kuburikidza nemamwe mafungu.
Hova idzi dzakaumbwa nearere hydrogen, zvichiita kuti pave nekudyidzana pakati pemapoka maviri enyeredzi, kazhinji zvichitungamira kune mamiriro anozopedzisira akuvadza maficha ekunze anoenderana nemagalactic disks.
Ose ari maviri Magellanic Clouds uye iyo Saturn Galaxy vane akasiyana uye anoshamisa morphological maitiro, maererano nehuremu hwawo uye maumbirwo adzo, zvinoburitsa zvinhu zviviri zvinozvisiyanisa kubva kuzvikamu zviviri izvi, uremu uye chimiro, kubva kune izvo zvinobva kumuenzaniso weMilky Way.
Dzimwe nhoroondo
Mamiriro akasarudzika eGore Guru reMagellan, rakananga kuSouth Pole yeEcliptic, zvinoreva kuti haringaonekwe chero nguva kubva kuMediterranean latitudes, saka rakaramba risingazivikanwe munguva dzekare.
Kutaurwa kwekutanga kweGore Guru reMagellan kunowanikwa muBhuku reNyeredzi rakanyorwa makore akapoteredza 964 nenyanzvi yenyeredzi yekuPersia Abd Al-Rahman Al Sufi. Ainzi Al Bakr, White Bull muSouth Arabia, nekuti Large Magellanic Cloud inoonekwa kubva kuSouth Arabia.
Amerigo Vespucci akanyora zvinotevera mutsamba parwendo rwake rwechitatu muna 1503-1504. Mukati mokutenderera kwake kwePasi, Ferdinand Magellan ndiye akatanga kuzivisa Madokero nezvokuvapo kweboka renyeredzi, iro nhasi rine zita rake. Wekutanga kudzidza iro Large Magellanic Cloud zvakadzama aive John Herschel., uyo akagara muCape Town pakati pa1834 na1838, achiongorora zvinhu 278 zvakasiyana-siyana zvairi.
The Large Magellanic Cloud yaionekwa segwara renzou riri padyo neGwara Renzou kusvika pakuwanikwa kweSagittarius Dwarf Elliptical Galaxy muna 1994. Nekuwanikwa kweCanis Major dwarf galaxy muna 2003, zita renyeredzi riri pedyo rakawira kune rekupedzisira.
Morphology uye zvinhu zveMagellan Cloud
Zvinoenderana neNASA's Extragalactic Object Database, iyo Large Magellanic Cloud inotsanangurwa seSB(s)m, yakavharwa spiral (SB) galaxy isina chimiro chisina kurongeka mhete uye isina bulge (m). Chitarisiko chisina kujairika chegwara renzou inogona kunge iri mhedzisiro yekudyidzana neMilky Way uye Diki Magellanic Cloud.
Kwenguva refu zvaifungidzirwa kuti gore reMagellan raive gomba renyeredzi rakati sandarara, senyeredzi inotenderera, uye kuti yaigona kufungidzirwa kuti iri chinhambwe kubva kwatiri. Zvakadaro, muna 1986, Caldwell naCoulson vakawana kuti mavara eCepheid ari kuchamhembe kwakadziva kumabvazuva kwenzvimbo yemakore makuru ari pedyo neMilky Way pane kusiyanisa kweCepheid mudunhu rekumaodzanyemba kwakadziva kumadokero. Nguva pfupi yadarika, iyi geometry yakatenuka yakasimbiswa necherechedzo dzeCepheid siyana uye hofori tsvuku muchikamu chehelium fusion. Aya mabasa anoratidza kuti kurerekera kweLMC kunenge 35º, tichifunga kuti 0º inoenderana nendege inotenderera kune yedu galaxy.
Iyo Huru Magellanic Cloud ine nyeredzi dzinenge mabhiriyoni gumi uye inosvika 10.000 35.000 chiedza-makore kuyambuka. Huremu hwayo hunosvika bhiriyoni gumi kuenzana neZuva uye chikamu chimwe mugumi cheMilky Way. Kufanana nemakwara enzou akawanda asina kujairika, gore rakakura rakapfuma mugasi neguruva uye parizvino riri munguva inoshanda yekuumbwa kwenyeredzi. Ongororo dzakasiyana-siyana dzakawana masumbu anosvika makumi matanhatu eglobular (ingori pasi pehafu yehukuru hweMilky Way), 10 mapuraneti nebulae, uye 60 masumbu enyeredzi akavhurika muLarge Magellanic Cloud, pamwe chete nemazana ezviuru zvenyeredzi hofori uye huru.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezveMagellan Cloud uye maitiro ayo.
