This fascinating edge-on galaxy lies off the handle of the Big Dipper in the constellation of Draco (The Dragon). Called the Splinter Galaxy, this galaxy shows a notable dust lane, but no significant central bulge. Very deep images reveal an expansive loop of faint stars that are a remnant of an encounter with a smaller galaxy in the distant past. If you look carefully just to the upper right of the Splinter you’ll find a tiny smudge; the distant galaxy PGC 4541551 glowing faintly at Mv 16.8.
