NGC 5907

NGC 5907 (The Knife Edge Galaxy)

NGC 5907 is a spiral galaxy and is oriented almost exactly edge on as viewed from our Earthly location.  It is very flat with little central budge.  Due to its flatness, and edge on prospective, it is known as The Splinter or Knife Edge Galaxy[1].  The galaxy is composed of mostly smaller dwarf stars[1] with very few giant stars.

The galaxy is located in the constellation Draco[1,2] at an estimated distance of approximately 50 million light-years[1].  The galaxy has a very prominent dust lane which blocks visible light[2] and restricts optical observations of background features[2].  Recent observations using the Spitzeer InfraRed Array Camera has detected a potentially massive thick stellar disk[2].
