The Milky Way's Mass is Much Lower Than We Thought
What is the mass of the Milky Way galaxy? It is difficult to measure the mass of a galaxy, and previous estimates appear to have been inaccurate. There is a new study that has used data from the Gaia spacecraft to calculate a more accurate mass for the Milky Way. The study found that the Milky Way is much less massive than previously thought, with a mass of about 200 billion solar masses. This means that the Milky Way has less dark matter than previously thought.
