<prompt> Bhala okuqhubekayo kwalesi sigaba - Ukuthola kukaHubble izinkanyezi ezingu - 11 eziguquguqukayo ze - Cepheid kwakuyisenzakalo esiyingqopha - mlando emkhakheni wezinkanyezi. Esebenzisa ubudlelwane be-Cepheid Period-Luminosity, uHubble wanquma ibanga elingu-. Lolu kwakuwuhlelo lokuqala olwalungaphandle kwamafu kaMagellanic olwalunqunywe ibanga lalo. I - Hubble yaqhubeka nale nqubo nge - Andromeda Galaxy ne - Triangulum Galaxy. Ukude kwakhe nomthala kwakungaphezu kakhulu kwenani likaHarlow Shapley leminyaka yokukhanya engu-300 000 ngobukhulu bendawo yonke. Kuleli phepha, uHubble waphetha ngokuthi Inkulumompikiswano Enkulu  <response>: ngo-1920 phakathi kukaHeber Curtis noShapley ngesilinganiso sendawo yonke kanye nemvelo ye-spiral nebula. Ngokushesha kwaba sobala ukuthi yonke imijikelezo yemithala enezingqimba eziyizigaxa empeleni yayiyimithala enezingqimba eziyizigaxa engaphandle kakhulu komthala wethu iMilky Way.
