NGC 5907 - The Splinter Galaxy, type Sb+, in Draco

Discovered by William Herschel in 1788.

NGC 5907 lies about 40 million light-years distant in the northern constellation Draco and it is also known as the Knife Edge or Splinter galaxy. NGC 5907 has long been considered a prototypical example of a warped spiral in relative isolation. Then 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.
