# astro: well, NGC1052-DF2 is not ab.normal, too

<< In 2018, a study published in Nature announced the discovery of a galaxy that apparently lacked dark matter. >>

<< The original article published in Nature stated that the galaxy (NGC1052-DF2) is at a distance of some 64 million light years from the Earth. However, this new research has revealed that the real distance is much less, around 42 million light years. (..) Thanks to these new results, the parameters of the galaxy inferred from its distance have become "normal," and fit the observed trends traced by galaxies with similar characteristics. >>

<< This implies that a significant part of the total mass must be made up of dark matter. >>
