In 1999 a star within IC 755 was seen to explode as a supernova and named SN 1999an.^[4] Supernovae like SN 1999an are classified as Type II^[4] and they are dramatic events that mark the end of the lives of massive stars. The supernova was discovered by the Beijing Astronomical Observatory Supernova Survey.
