What structure classifies the Milky Way galaxy according to astronomers?
Answer
A barred spiral galaxy
The Milky Way is classified as a barred spiral galaxy. This classification is based on its overall morphology, which includes a prominent central structure shaped like a bar composed of older stars. From the ends of this central bar, the characteristic spiral arms, such as the Sagittarius Arm, emanate and wind outward. This bar structure is a significant feature that distinguishes it from regular spiral galaxies that lack this elongated central component, influencing the overall dynamics and structure from which the spiral arms develop.
