- Diameter: Spans about 80,000 to 100,000 light-years.
- Apparent Magnitude: Around 9.0, making it one of the brightest galaxies in the northern hemisphere visible through small telescopes.
Scientific Interest
- Star Formation: Its core exhibits exceptionally high rates of new star formation, known as starburst activity.
- Central Bar: The central "bar" acts as a funnel, channeling gas toward the center of the galaxy and fueling the birth of new stars.
- Nuclear Ring: The Hubble Space Telescope has revealed a ring of bright, young star clusters surrounding its nucleus.
