It possesses a diffuse core which is the largest core of any galaxy known to date, [5] and contains a supermassive black hole, one of the largest discovered. [5] IC 1101 is located at 354.0 megaparsecs (1.15 billion light-years) from Earth. It was discovered on 19 June 1790, by the German-British astronomer William Herschel. [6]

List of the largest known stars in Andromeda and Triangulum galaxies Star name Solar radii (Sun = 1) Galaxy Method [a] Notes Theoretical limit of star size (Andromeda Galaxy) ≳1,750 [11] L/T eff: Estimated by measuring the fraction of red supergiants at higher luminosities in a large sample of stars. Assumes an effective temperature of 3,625 K.
NGC 6872 is interacting with the lenticular galaxy IC 4970, which is less than one twelfth as large. [2] [3] The galaxy has two elongated arms with a diameter based on ultraviolet light of over 522,000 light-years (160,000 pc), and a D 25.5 isophotal diameter of over 717,000 light-years (220,000 pc), making it the largest known spiral galaxy.
The Hercules–Corona Borealis Great Wall (HCB) [1] [5] or simply the Great Wall [6] is a galaxy filament that is the largest known structure in the observable universe, measuring approximately 10 billion light-years in length (the observable universe is about 93 billion light-years in diameter).
UGC 2885 (Rubin's Galaxy, [10] nicknamed "Godzilla galaxy" [11]) is a large barred spiral galaxy of type SA(rs)c in the constellation Perseus.It is 232 million light-years (71 Mpc) from Earth and measures 463,000 ly (142,000 pc) across, making it one of the largest known spiral galaxies.
