NGC 1032 is a lenticular galaxy of the Hubble type S0 / a in the constellation Whale south of the celestial equator . It is estimated to be 121 million light years from the Milky Way and about 120,000 ly in diameter.
In January 2005, the faint supernova SN 2005E lit up in NGC 1032 . The observations showed that neither the amount of star matter ejected nor its chemical composition matched any of the previously known explosion mechanisms for stars . Current research suggests that this is a process that occurs in two closely circling white dwarfs .
The object was discovered on December 18, 1783 by the German-British astronomer Friedrich Wilhelm Herschel .
