METAGALAKTIKA

METAGALAKTIKA (az meta… va Galaktika), majmui hamai sistemahoi sitoragiest, ki yak qismi on majmui tamomi galaktikahoi bo teleskophoi hozirazamoni optiki, rentgeni va radioteleskopho mushohidashudaro (taqr. 1 mlrd) faro megirad Bazan mafhumi Metagalaktikaro bo mafhumi Konnot ayniyat medonand, harchand ki vujud doshtani Metagalaktikakhoi digar az ehtimol dur nest. Metagalaktikaho, radiogalaktikaho, kvazarho va digar obekthoi astronomi ba hayati Metagalaktika dokhil meshavand. Dar fazoi bayni in obektho sitorahoi judogona, gazhoi tunuku jangi kayhoni, afkanishoti elektromagnitiyu korpuskulavi pahn shudaand. Dar daruni tarokumhoi galaktiki boshad, bazan gardu changi kayhoni mushohida meshavad. Ba qadri takmil yoftani vositaho mushohidai obekthoi nav ba navi kayhonii kashf mekunand va payvasta tassavuroti ilmii mo dar bobi tarkibi Metagalaktika toraft vaseu gani gardad. Bino ba malumoti navin miyonai modda dar qismi mushohidashudai Metagalaktika ba 10-10 gsm merasad. Lekin dar dokhili Metagalaktika shkilahoi buzurgu gayriyakjinsa bisyorand, ki az jihati andozavu naqib khele mukhtalifand. Chunonchi, tarokumhoi galaktikie hastand, ki dahho sadho va hatto hazorho galaktikahoro dar bar megirand. Galaktikai mo boshad, yakjoya bo yakchand galaktikahoi ba vay nazdik ba hayati tarokume dokhil meshavad, ki onro guruhi mahallii galaktikiaho menomand. Tarokumi mazkur dar navbati khud ehtimol ba hayati yak abri buzurgi kayhoni dokhil shavad. Dar yadroi in abr tarokumi azime hast, ki az chandin hazor galaktika iborat buda, har az burjhoi Sunbula va Gesu (az mo dar masofai taq 40 haz. soli nur) namoyon meboshad. Dar borai shaklu andoza va sokhti M. hanuz yagon malumoti daqiqi astronomi dastras nashuda ast.
