NGC 5907 – Knife Edge Galaxy

Details from Wikipedia: NGC 5907 (also known as Knife Edge Galaxy or Splinter Galaxy) is a spiral galaxy located approximately 50 million light years from Earth.In the Catalogue of Named Galaxies, it is called Circumfusus Draconis, or the enveloped galaxy, due to the large arcing structures that can be seen in long-exposure images. It has an anomalously low metallicity and few detectable giant stars, being apparently composed almost entirely of dwarf stars.It is a member of the NGC 5866 Group.

NGC 5907 has long been considered a prototypical example of a warped spiral in relative isolation. In 2006, an international team of astronomers announced the presence of an extended tidal stream surrounding the galaxy that challenges this picture and suggests the gravitational perturbations induced by the stream progenitor may be the cause for the warp.
