Within NGC 4319 spiral arms, striking dust lanes, and a large, subtle central bar are all clearly visible. The dust lanes are of particular interest — the distorted dark patches suggest that NGC 4319 interacted with a nearby galaxy in the past.
The view is 1.8 arcminutes across, corresponding to some 40,000 light-years. The image is a composite of two shots taken in 1997 and 2002. A total of 1.4 hours of Hubble observations were added to create the picture seen above.
