NGC 5907(also known asKnife Edge GalaxyorSplinter Galaxy) is aspiral galaxylocated approximately 50 millionlight yearsfromEarth.[2]William Herscheldiscovered the galaxy in 1788.
Characteristics
[edit]NGC 5907 has an anomalously lowmetallicityand few detectablegiant stars,being apparently composed almost entirely ofdwarf stars.[3]It is a member of theNGC 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.
Onesupernovahas been observed in NGC 5907: SN 1940A (type unknown, mag 14.3).[4][5]
Anultraluminous X-ray sourceis located in the galaxy.[6]
Location
[edit]
- The edge-on galaxy is seen in the constellation Draco, near the stariota Draconis.It is seen in the sky near to the much more distant galaxyNGC 5965.
NGC Identification
[edit]NGC 5907 is also known as NGC 5906.[7][8]This second NGC number refers to a fainter part of the galaxy[7]lying west of the dust lane[8]that was recorded by astronomer and physicistGeorge Johnstone Stoneyon April 13, 1850.[7]
