2021年2月21日 · One red supergiant star in this galaxy underwent a supernova explosion in March 2012 (SN II-P 2012aw). It was classified as a Type II-Plateau (II-P) because of the pronounced flattening of its light curve after 26 days of its peak. This supernova was captured by numerous amateur and professional astronomers at the time.
