|Description:||This unusual galaxy has a bright ring of star
forming regions in clusters around the core. Moving outward, there is
a collection of older stars followed by another ring of young stars.
Continuing further out, there is a dust area and beyond that a galactic glow
that extends nearly to the total height of the image. The latter areas
depend on a carefully adjusted monitor to see.
