La spiral galaxy messier 83 iri muboka renyeredzi reHydra uye inoshamisa yakabatana negora renyeredzi rinogona kuonekwa nemabhainokura. Yakaongororwa naPierre Mechain muna 1752 uye yakawedzerwa kubhuku raCharles Messier muna 1781. Iyo inozivikanwawo seyekumaodzanyemba kwePinwheel galaxy.
Kuburitsa data ye spiral galaxy messier 83
Kushandisa HAWK-I chishandiso teresikopu VLT iri paParanal Observatory muChile, ESO vanoongorora nyeredzi vakakwanisa kutora inomiririra yakanakisa yespiral galaxy messier 83 kusvika parizvino.
Mupfungwa iyi, nyeredzi iyi inofungidzirwa se "hanzvadzi" yeMilky Way yedu, sezvo iine chimiro chemhepo uye zvakare nyeredzi iyo inoyambuka axis yayo. Pane rimwe divi, messier 83 inowanikwa chaizvo mamirioni gumi nemashanu echiedza-makore kure (muboka renyeredzi Hydra) uye inotenderera anopfuura 15 chiedza-makore (inenge 40% yehuwandu hweMilky Way yedu). Iri gomba renyeredzi rinogona kudzidzwa pamwe chete nemamwe mitumbi yenyeredzi senge Centaurus A galaxy, iyo inofadzawo zvikuru mune zvenyeredzi.
Nzvimbo chaiyo ye spiral galaxy messier 83
Nekuda kwemaonero akaderera eMaodzanyemba aMessier 83, zvakaoma kuwana mu hemisphere kuchamhembe, pasinei nekureba kwayo uye muviri. Kutenderedza chinhu chakafumurwa, chinomisikidza kuenzanisa gamma kana pi Hydrae. Sezvo gamma iri hupamhi hwechibhakera kuchamhembe kwakadziva kumadokero kwe pi uye hupamhi hwechibhakera kumaodzanyemba kwakadziva kumadokero.
Kana iwe uri kumaodzanyemba kwehemisphere, tsvaga iota uye theta Centauri uye ingosvetuka 1, 2, 3, 4, 5 nyeredzi kare. M83. Kuti uione kubva kuchamhembe, ingangoita 3 kana 4 ″ inoratidzira uye denga dema inokumbirwa, nepo vekumaodzanyemba vachigona kuiwana nyore nemabinoculars madiki.
Nyanzvi Zvakazarurwa
La girazi spiral messier 83 inoonekwa seimwe yakakura uye yakakomberedzwa galaxi yenyeredzi kwatiri. girazi Iyo inoshamisa uye, panguva imwechete, isinganzwisisike, yakange iri muridzi wenhamba yakawanda yekuputika kwe supernova, uye yakasimbiswa kuti ine nucleus mbiri yekuchenjerera mukati mepakati axis.
Inoonekwa seimwe yemapoka enyeredzi anoshamisa erudzi rwayo mumatenga edu. Iyo inhengo yakatanhamara yeboka remapoka enyeredzi anozivikanwa seCentaurus A kana boka reM83 iro zvakare rine huruva. centaurus A uye iyo isina kujairika NGC 5253 senhengo. Hupfumi hweboka iri remapoka enyeredzi hunogonawo kuongororwa mune zvimwe zvidzidzo zve mapoka enyeredzi.
Mupfungwa iyoyo, spiral galaxies inouya mukuoma kwemakirasi zvichienderana nechitarisiko chavo uye kurongeka, semuenzaniso, kusapinda kwemaoko avo uye typologies yepakati bulge. Messier 83 ine "bar" yenyeredzi inocheka nepakati peaxis yayo, zvichitungamira kune iyo encoding seyakavharirwa. The Milky Way nenzira imwechete ine chekuita nechimiro ichi.
Masayendisiti mazhinji anofunga kuti tsvimbo idzi kuita senge tripper, kupfapfaidza gasi pakatarisana negwara renzou. Chipfunga ichi chinoshandiswa kugadzira nyeredzi itsva uyezve kudyisa gomba dema repakati pePasi. girazi, vachifumura chikonzero nei vakawanda Midzimu Yakakomberedzwa neiyo spiral galaxy Messier 83, ivo zvakare vane kukurumidza uye kupenya nzvimbo dzepakati.
Chakavanzika chepakati pe spiral galaxy messier 83
Zvisinei, pakati peMessier 83 haanzwisisike uye haajairiki. Ndiko kuti, gomba dema rakakura papakati paro harisi roga. Kutenderera kunoshamisa uku kunoratidza kusarudzika kwakatanhamara senge kaviri nucleus, chinhu chinoshamisa chakawanikwawo mugwara renyeredzi renyeredzi. Andromeda. Izvi hazvireve kuti Messier 83 inobata maburi matema maviri epakati, asi kuti gomba rayo guru dema rinogona kuvharidzirwa nemhete ine nyeredzi, iyo inotenderera pedyo negomba dema uye ichipa kutaridzika kwekaviri nucleus.
M83, mukoma mudiki weMilky Way
Zvinoshamisa renyeredzi renyeredzi inoratidzwa nevesainzi saMessier 83. Mukuwirirana, inogarogarwawo seSouthern Pinwheel, nekuda kwekufanana kwayo nechamhembe kwePinwheel galaxy Messier 101. Spitzer Space Telescope yeNASA inotiratidza, mune zvakadzama, kuparadzirwa kwe infrared kwezvinoitwa nevanhu vazhinji. funga seMilky Way yedu.
Nezvezviri pamusoro apa, dai taiva pakati chaipo pedhisiki reGwara Renzou, tinogona kuona nyeredzi yedu kubva panzvimbo yakavharika yekuona yakatarira pasi. Isu tinoratidza Messier 83 nenzira imwechete yakatarisana nechiso, tichifambisa kuenderana kwekukwanisa kuona vhiri rayo zvakadzama. Tsvakurudzo iyi inobatsira vaongorori kuti vaongorore izvo zvedu girazi kana tikakwanisa kubudirira takananga pamaonero ari nani.
Kune rimwe divi, seGwara redu renzou, spiral galaxy messier 83 inorongedzerwa seyakakomberedzwa galaxy nekuda kwepatani yemabhawa. nyeredzi dzinofamba pakati payo. Iyi nharaunda yebhawa inonyanya kutaridzika mu infrared, sezvo nenzira imwechete isu tinokwanisa kusiyanisa kupatsanurwa kweS-yakaita curve yehupfu hweshear nekushandisa iyo yakananga nyeredzi bar.
Muhurongwa uhu hwemazano, iyi arc yeguruva iri mukati memukati inobatana nemaoko akanyanya kuvharika ari mudhisiki rekunze, anowanzoonekwa seanokatyamadza girinhi-tsvuku inopenya inopenya. pakati pemaoko Midzimu primordial tinoonawo yakaoma membrane yeguruva inopinda mu disc yose.
Zvakare, nepo Messier 83 iri kure nemamiriyoni gumi nemashanu kubva pachiedza-makore, mumamiriro ezvinhu ari rimwe remakwara enzou ari pedyo zvikuru ari mudenga. Izvi zvinopa vatsvakurudzi kuwirirana kwakanaka kwekuona nyeredzi iyo, kunyange hafu yakakura, inoratidzika yakada kufanana mukugoverwa kune galaxy yedu, iyo Milky Way.
Saizvozvo, chiedza che infrared chakadaro chine wavelength e3,6 uye 4,5 microns chinoratidzwa nebhuruu negirinhi chinoratidza kunyanya kupenya kwenyeredzi. Iyo 8-micron mwenje inoiswa mutsvuku; Mutoro we chiedza yenyeredzi pa8 microns yakabviswa kubva kumashure kuratidza zvirinani maumbirwo eguruva pamwe nekumashure kwemapoka enyeredzi.
Masayendisiti anoratidza izvo zvinogadzirwa zvakanyanya kubva kumiganhu yegwara renyeredzi
Tinokwanisa kazhinji kuona zviri kuitika kana kuti boka renyeredzi rinoonekwa nekuparadzirwa sei, asi tichiri kutambudzwa nekusahadzika pamusoro pezviri mberi. Zvakanaka mupfungwa iyi tine kuti nzvimbo dziri pedyo pedyo nechokumaodzanyemba kwePinwheel galaxy, kana kuti spiral galaxy Messier 83, dzinoratidzwa mumufananidzo uyu wakarongeka kubva kuGALEX space observatory ye NASA uye Iyo Yakakura Kwazvo Array. Pinivhiri reblue nepingi paaxis ndiro dhisiki renyeredzi renyeredzi, ukuwo zvinopeperetsa, zvakaita seribhoni maoko akagadzirwa.
Zvakare iyo Galaxy Evolution ExplorerNdicho teresikopu ultraviolet tsvakurudzo. Ongororo dzavo, dzakafumurwa, dzinosimbisa mapoka ari kure zvikuru enyeredzi duku muboka renyeredzi pa140.000 XNUMX light-years kubva muaxis yaro. Kuongorora kwakakura kwazvo kweArray kunofumura kuratidzwa kweredhiyo mutsvuku. Vanotara pasi pemaatomu ehaidhirojeni ane gasi, kana kuti zvinhu zvakaomarara zvenyeredzi, zvinoumba maoko marefu, akatambanudzwa.
Kune rimwe divi, vazivi venyeredzi vanonetsekana kuti nyeredzi dzemucheche dzinoenderana nemaoko akawedzerwa, nekuti izvi zvinovabatsira kuti vanzwisise zviri nani kuti nyeredzi dzinogona kuumbwa sei mu "masango" egirazi, uye mune ino spiral galaxy Messier 83.
