Although some references describe M94 as a barred spiral galaxy, the "bar" structure appears to be more oval-shaped. The galaxy has two ring structures: an inner ring with a diameter of 70 arcseconds and an outer ring with a diameter of 10 arcminutes. The inner ring is a site of strong star formation activity and is sometimes referred to as a starburst ring. | |
