Thanks to the latest Gaia satellite catalogue from the European Space Agency (ESA), an international team led by astronomers from the Paris Observatory – PSL and the CNRS has achieved the most accurate measurement of the mass of the Milky Way. Published in the Astronomy & Astrophysics journal on September 27, 2023, this study opens important questions in cosmology, particularly on the amount of dark matter contained in our Galaxy.
