NGC 925 - Barred Spiral Galaxy in Triangulum

NGC 925

NGC 925 is a barred spiral galaxy that is viewed nearly face-on. The arms are flocculent, referring to their asymmetric nature. It is possible that this was caused by interaction with a nearby galaxy in the past. There are many star-forming regions in the arms. The numerous, newly formed stars give the arms a blue hue.
