NGC 1638 (N)
There is no evidence for any dust structures within the central
kiloparsec of this galaxy. Even at larger scales, there only appear to
be a few small star formation regions with some associated dust.

NGC 1638 has a definite spiral structure in
the disk of what would otherwise be an S0. The
spirals are caused either by smooth dust lanes
threading through the disk or by broad, massive,
smooth, luminous arms of a more advanced
(better-defined) type than shown on the preceding
page. One prominent dust lane is clearly seen in
the print. The subtle spiral structure throughout
the disk can best be seen by viewing the print at
a distance.
The arms are of the MAS type. This galaxy
is one of the earliest examples of what are seen as
full filamentary arms later in the Sa sequence
(panels 77-80) and throughout the Sb and Sc
sections.
