NGC 5907 (also known as
Knife Edge Galaxy or
Splinter Galaxy) is a
spiral galaxy located approximately 50 million
light years from
Earth.
[2]William Herschel discovered the galaxy 1788.Characteristics of NGC 5907NGC 5907 has an anomalously low
metallicity and few detectable
giant stars, being apparently composed almost entirely of
dwarf stars.
[3] 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. The existence of part of these tidal streams has been recently challenged by some deeper surveys.One
supernova has been observed in NGC 5907: SN 1940A (type unknown , mag 14.3).
[4][5]An
ultraluminous X-ray source is located in the galaxy.
