Comment

NGC 1055 is an edge-on spiral galaxy located in the constellation Cetus that has a prominent nuclear bulge crossed by a wide, knotty, dark lane of dust and gas. The spiral arm structure appears to be elevated above the galaxy's plane and obscures the upper half of the bulge. Discovered on December 19, 1783 by William Herschel from his home in Slough England. It is a binary system together with the bright spiral galaxy M77 (NGC 1068). Based on the published red shift, (Hubble Constant of 62 km/s per Mpc) a rough distance estimate for NGC 1055 is 52 million light-years, with a diameter of about 115,800 light-years. The separation between NGC 1055 and M77 is about 442,000 light-years.
