A large disk-shaped aggregation of stars, gases and dust in which the solar system is located is called milky way galaxy. Andromeda is the galaxy which is nearest to the milky way galaxy.
Earth is located about halfway between the center of the Milky Way and its outer edge. Light at the galaxy's center takes 25,000 light-years to travel from Earth. Between March milky way galaxy is visible if you get up before dawn, in summer it can be seen at midnight, and by October it's on show right after dusk. If there's no light pollution to block your view it's possible to see the Milky Way galaxy arcing overhead.
