2023-09-27 Gaia finds the Milky Way contains less dark matter than previously thought

27 September 2023Until now, the Milky Way was estimated to weigh about 1E12 solar masses. Part of this mass consists of the ordinary matter like stars and the cold gas in the Milky Way, expected to weigh about 0.6E11 solar masses. The rest of the mass of the Milky Way is made up of dark matter, a type of matter still unknown to us. The expected dark matter in...
