NGC5907 Core
Inverted Tidal Tail

NGC 5907 is a spiral galaxy located approximately 50 million light years from Earth. 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. Then in 2006, an international team of astronomers announced the presence of an extended tidal stream surrounding the galaxy 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. The galaxy was discovered in 1788 by William Herschel. [Text adapted from Wikipedia]
