Andromeda nebula - Hooyga kuwa sacraments ah

Andromeda Galaxy waa mid ka mid ah ugu dhow in ay noo kooxahaasi Galaxy guriga xiddigaha weyn. Waa qayb ka mid ah koox wax-u maxaliga ah ee falagyada, kuwaas oo xubno ka tirsan, marka lagu daro waxa ay u, yihiin waa calooshiisa Jidka la Galaxy Saaxiibka iyo Galaxy ee Saddex Xagalka ah (kuwaas oo sidoo kale yeelan karaan satalayt, weli ogeyn). Dhab ahaantii, ugu dhow Jidka calooshiisa ku jira kooxahaasi yar - ka waaweyn iyo kuwo yaryar Magellanic daruuro. Galaxy ayaa lafteedu mideeya oo ku saabsan a trillion xiddigaha (taas oo ah shan jeer ka badan noo gaar ah), iyo gacan ay goobo - in ka badan 110 kun oo sano iftiin. Andromeda Galaxy waa naga fogaan ah laba milyan iyo badh sano oo iftiin ah iska, iyo si aad u hesho si ay ugu fiican ee maanta pride qaadan lahaa 46 bilyan oo sano. Tani waa ugu yaraan lix jeer ka weyn yahay dhulka ka jira. Tiradani waxay yihiin xitaa ay adag tahay in la damacsan!

Taariikhda indhaynta Galaxy ah, deris

cluster cufan xiddigaha samada oo kale waxaa lagu arkay in qarniyadii dhexe. Gaar ahaan, mid ka mid ah taariikhda Arab of nebula Andromeda loo gudbiyo sida daruur yar. Tani rucub xiddigaha ku yaalla shir tagayso ee Andromeda (taas, dhab ahaantii, nebula ay magaca helay) ayaa lagu arkay by cirbixiyeyaasha qarniyo. Si kastaba ha ahaatee, ma jiro horumarka la taaban karo ee ay description. Si kastaba ha ahaatee, awooda farsamada ayaa loo ogol yahay aadanaha si ay u sameeyaan tallaabo hore ee arrintan la xiriira. In 1885, waxaa jira dhacdo xiiso leh - in Galaxy ee Andromeda qarxay supernovaer ah, iyo dareenka ah cirbixiyeyaasha adduunka oo dhan in ay ciriiriga u soo jeestay. Si kastaba ha ahaatee, sida laga soo xigtay mid ka mid ah version, ayay ku qarxay muddo dheer ka hor, dhowr milyan oo sano ka hor, laakiin xaqiiqada ah in culumadu aqbalay dhalashada xiddiga cusub - ka qaraxa, taas oo kaliya hadda (ama halkii, in 1885) oo keliya nuurka in Earth yimid. Andromeda nebula, photos of taas oo markii ugu horraysay laga helay 1887, u muuqataa in ay cirbixiyeyaasha sida kooxdu weyn faraha ka mid ah jirkooda. daahfurka cajiib ah ka sameeyay 1921 by Vesto American ah Slipher. Xisaabayo dhabbihii ee Galaxy ah, waxaa la helay in nebula Andromeda la xawaaraha wayn si toos ah gobays iyo ilaa dhinaca reer Jidka calooshiisa ka. Sida laga soo xigtay xisaabo casriga ah ee cirbixiyeyaasha, in 4 bilyan oo sano waxay ku milmaan doonaa labada falagyada. Tani ma u eg isku dhaceen laba rucubood oo xiddigaha laakiinse hubaal mari urursadaan muhiim ah oo la beddelo Galaatiya iyaga u gaar ah. Hubi in badan lagu qasbi doonaa oo jidhka ah, xataa gudahood Galaxy ee dhowaan la sameeyey ee meel interstellar Waxaan ahay. Waxa xiiso leh in 1993 ee xarunta of nebula Andromeda la helay cluster kaloo xiddigaha. Waxaa laga yaabaa in ay tahay raad ee Galaxy a, nebula nuugo malaayiin sano ka hor.

Features nebula

Sida ay fikradaha ah jaamacadaha UCLA casriga ah, in xarumaha ugu falagyada muquuninta qabno godad madow supermassive. Waa ay adag tahay in la arko, waayo, meel tuulmo badan oo jidhadhka ee xarunta of spirals ah, iyo sidoo kale sabab u la'aanta iftiinka, ama laga fekerayo iftiinka. Si kastaba ha ahaatee, godadka madow waxaa lagu ogaan karaa by logu sida ay u saamayn waxyaabaha kale. Waxaa cajiib ah in muhimka ah ee Galaxy Andromeda waa isku darka laba musharax sida godadka madow supermassive.
