Which galaxy type exhibits a size and mass variability broader than any other type?
Answer
Elliptical galaxies
Elliptical galaxies demonstrate a range in both size and total mass that surpasses any other classification of galaxy in the cosmos. On the low end of the scale are the dwarf ellipticals, which can be incredibly small, containing only tens of millions of stars and approaching the lower size limits of large globular star clusters. Conversely, the supergiant ellipticals, typically found dominating the cores of massive galaxy clusters, are the largest known structures, sometimes containing over one hundred trillion stars and boasting diameters exceeding 700,000 light-years. This immense scope from dwarf to supergiant defines their variability relative to spirals or irregulars.
