SN 2004dj is one of the most studied and visually significant supernovae in recent astronomical history. It occurred in the galaxy , located approximately 11 million light-years away in the constellation Camelopardalis.

It was rare to find a supernova within a well-studied star cluster, allowing for precise dating (the cluster is approximately 14–20 million years old ) and mass estimation of the progenitor. 🏥 Medical Research Coding: 04DJ SN 2004dj is one of the most studied

The star that exploded was identified as a Red Supergiant located in the compact star cluster Sandage 96 . It had an estimated initial mass of 12 to 15 times the mass of our Sun. SN 2004dj is one of the most studied
