A group of researchers from the Instituto de Astrofísica de Canarias (IAC) has clarified a 2018 mystery in the field of extragalactic astrophysics: The supposed existence of a galaxy without dark matter. The most relevant datum found via the new distance analysis is that the total mass of this galaxy is around one-half of the mass estimated previously, but the mass of its stars is only about one-quarter of the previously estimated mass. A distance of 13 Mpc resolves the claimed anomalies of the galaxy lacking dark matter,
