Dwarf galaxies are small galaxies that contain fewer stars and have lower luminosities than typical galaxies like the Milky Way. These galaxies are often found orbiting larger galaxies as satellites. Dwarf galaxies are fascinating objects of study for astronomers because they can provide valuable insights into the formation and evolution of larger galaxies. They are also important for understanding dark matter and the overall structure of the universe. Research on dwarf galaxies typically involves studying their stellar populations, dynamics, and interactions with larger galaxies.
