The Whirlpool Galaxy (M51A or NGC 5194) and (M51B or NGC 5195, left). The Whirlpool Galaxy is a grand-design spiral galaxy, interacting with NGC 5195, a dwarg galxy. Both galaxies are located 23 ± 4 million light-years away in Canes Venatici.
This image by NASA's Hubble Space Telescope shows a face-on view of the Whirlpool Galaxy (M51). Taken in visible light, it highlights the attributes of a typical spiral galaxy, including graceful, curving arms, pink star-forming regions, and brilliant blue strands of star clusters.
