Supernova
editOne supernova was discovered by W.D. Li from the University of California via unfiltered images taken from the Kazman Automatic Imagining Telescope, in UGC 9425. Called SN 2001ck, the supernova was located 5".8 west and 3".0 north of the nucleus.[6] Further investigations by astronomers from Harvard Smithsonian Center for Astrophysics, confirmed it as a type Ia supernova with an expansion velocity of 11,000 kilometers per seconds.[7][8]
