This spiral galaxy located in the constellation Draco is about
40 million light years from earth. Our line of sight is almost
perfectly along the flat plane of the galaxy, and so we see
only its profile with dark lanes of dust blocking much of the
light. To the right and below NGC 5907 is a dwarf galaxy companion,
PGC 54419. A dwarf galaxy much like this one probably helped to
form the dramatic dim loops of stars that spiral around NGC 5907;
these loops are too dim to appear in this image, but perhaps some day
I'll add several hours of exposure to this and they'll appear. In the
meantime, you can see them here.
