Summary[edit]

Description
English: NGC6946 (Arp 29) is a face-on SAB(rs)cd galaxy in the constellation Cygnus. This classification refers to the presence of a small core with multiple well-defined arms (cd), with a poorly-developed bar across the middle (AB) and an inner confused ring (rs). Nearly twenty million light-years from Earth, it is over seventy thousand light-years across and more than fills this picture. At least one supernova has been observed in this galaxy. KPNO 4-meter Mayall telescope, 1975.
