IC 755 is a spiral galaxy that lies 70 million light-years away in the Coma Berenices constellation. In 1999 a star within IC 755 was seen to explode as a supernova and named SN 1999an. Supernovae like SN 1999an are classified as Type IIs 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.
