Barred spiral galaxies are a type of galaxy characterized by a central bar-shaped structure made of stars, which extends from the core and connects to spiral arms. These galaxies often have a distinct spiral pattern, with arms that wind outward from the ends of the bar. An example of a barred spiral galaxy is NGC 1300. The presence of the bar influences the motion of stars and gas within the galaxy, often leading to increased star formation in the spiral arms. Barred spiral galaxies are classified as type SB in the Hubble sequence, which categorizes galaxies based on their shapes.
