Centaurus A är en gigantisk elliptisk galax i stjärnbilden Kentauren, och är en närmaste aktiva galaxen.[1] Den befinner sig strax utanför lokala galaxhopen.[5] Centaurus A tros innehålla 2000 klotformiga stjärnhopar, varav många ljusare och tyngre än de ungefär 150 klotformiga hoparna i vintergatan.[5]
