This galaxy is called M63 because of its listing the the Messier catalog. It’s also known as the Sunflower Galaxy. M63 has a spiral shape with no central bar feature and moderate to loosely wound arms. The spiral structure isn’t readily apparent in visible light. However, when viewed in the near infrared, the galaxy’s two spiral arms are easily seen. Each arm wraps 150° around the galaxy and extends up to 13,000 light-years from the nucleus.
