Notes

NGC 5907 is a spiral galaxy located approximately 50 million light years from Earth.

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.

NGC 5907 is also known at the Knife Edge or Splinter galaxy.
