      How the Galaxy Works

        The galaxy is a massive, gravitationally bound system consisting of stars, stellar remnants, interstellar gas, dust, and dark matter. It is estimated to contain over 100 billion stars, with the Milky Way being one of the largest and most massive galaxies in the local universe. At its center lies a supermassive black hole, which is thought to have formed through the merger of smaller black holes. The galaxy's shape is influenced by the distribution of its stars, gas, and dark matter, which are all held together by gravity.
