NGC 3938 is a face-on Spiral Galaxy in the
Constellation of Ursa Major. It has a small bright, diffuse
nucleus in a bright inner lens. There are two bright,
filamentary, knotty arms that begin near the center and unwind
for about half a revolution, before branching. Thin dust lanes
are present throughout the inner arm region, the inner disk, and
the inside of the principal luminous arms. Based on the
published red shift a rough distance estimate for NGC 3938 is 43
million light years, with a galaxy diameter of about 67,000
light years.
